Full textAbstract:
The effects of pain suffered from musculoskeletal disorders by dental professionals may lead to reduced work hours, loss of production, and early retirement. Although third- and fourth-year dental students are provided lectures about musculoskeletal disorders, proper positioning and ergonomics, they are at an increased risk of developing MSD. This study was conducted to evaluate the prevalence on musculoskeletal disorders in third- and fourth-year dental students and to determine if third-year dental students experience more MSD pain than fourth-year dental students at the University of Tennessee Health Science Center College of Dentistry. A total of 50 third- and fourth- year dental students responded to the online questionnaire, 21 third-year dental students and 29 fourth-year dental students. Both third- and fourth-year dental students report experiencing MSD pain over the last twelve months. There was no statistically significant difference between MSD pain felt between third- or fourth-year dental students.

Full textAbstract:
Performance-related musculoskeletal disorders in musicians are common due to the biomechanics required in their craft. Unfortunately, injuries can cause many to abandon music, so determining the best approach to treatment and prevention is key. This case study’s importance is to evaluate the optimal approach to carpal tunnel syndrome in a drummer. The patient is a 55-year-old male full-time drummer with a history of diabetes mellitus and osteoarthritis, who presented to clinic with chronic bilateral hand numbness and tingling that had been present for years. The location of the symptoms were mainly in the palmar aspect of the 1st digit, 2nd digit, 3rd digit, and the radial side of the 4th digit. The symptoms had progressively been worsening, and his discomfort was initially rated at a 10/10 bilaterally. He had tried over-the-counter and prescription anti-inflammatory medications as well as braces without improvement. His physical exam was positive for Tinel’s sign. The diagnosis of carpal tunnel syndrome was eventually made. The patient was treated with bilateral ultrasound-guided carpal tunnel injections with lidocaine and methylprednisolone. The other component of treatment was relative rest, which allowed us to tailor treatment to his drumming. After treatment, his discomfort was rated at 0/10 bilaterally, and he was drumming without issue. It was found that relative rest and carpal tunnel injections are effective in treating carpal tunnel syndrome in drummers. His treatment was tailored to his specific instrument type, which was a key component to the success. Upon review, there is limited to no specific information on treating drummers as a specific group in the literature, but rather more information on treating musicians as a whole. Different instrumentalists have different postures and repetitive movements, so future studies would do well to examine the individual biomechanics of the different instrumentalists to better tailor treatment and prevention.

Sutherland, Alasdair G. "Post-traumatic psychopathology and recovery after musculoskeletal injury." Thesis, University of Aberdeen, 2002. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.247763.
Full textAbstract:
Introduction: Psychological disturbances after combat and major civil accident has long been recognised, but it has become clear that more "everyday" trauma such as road traffic accidents can lead to similar problems. Post-traumatic Stress Disorder (PTSD) is the extreme of a spectrum of Post-traumatic Psychopathology (PTP), is known to influence the Metabolic Response to Trauma (MRT), and may affect physical recovery after injury. This thesis details the results of a large study of accident victims, following their physical, physiological and psychological recovery. Methods: Cohort study of 200 patients aged 16-60 y with musculoskeltal injuries. The patients completed questionnaires that examined their psychological health (GHQ), and their physical and pyschosocial health (SIP, SF-36, MFA), and trauma scores were calculated. Assessments were made on admission (vice health before the accident), and were repeated at two and six months. A subgroup of 82 patients also gave blood samples at each of the follow up points, and these were analysed for pro-inflammatory markers of the MRT (CRP, IL-6, soluble IL-6 receptor, and TNF-a). Results: Follow up was 79% and 75% at two and six months for the main group, and 82% and 59% respectively for the Metabolic Markers subgroup. PTP was found in 11% of patients at initial assessment, 46% at two months and 22% at six months. It was strongly related to impaired physical and psychosocial functioning There were also associations between PTP and sIL-6r and TNF-a at six months. Injury Severity Score was predictive of PTP at two and six months. Discussion: There are strong associations between psychological and physical health after musculosketal trauma. Injury Severity Score is predictive of this psychological disturbance, which is also associated with disturbance of pro-inflammatory markers. Truly holistic care of patients who have suffered musculoskeletal trauma must include management of the psychological injury as well as the more obvious physical injuries.

Chesney, David. "Congenital Talipes Equinovarus : management and outcome." Thesis, University of Aberdeen, 2001. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.251868.
Full textAbstract:
Congenital Talipes Equinovarus is the commonest congenital musculoskeletal disorder with an incidence of 1 in 1000 live births. Although there has been much research into various aspects of the condition, there are still many unanswered questions. CTEV shows a spectrum of severity. In practice, a small percentage of cases resolve completely shortly after birth, but the remainder require further management with surgery in up to 80% of patients in some series. In children under the age of 6, soft tissue operations are often all that is required. After that age however, bony procedures are often necessary as the growing bones adapt to their abnormal environments. A number of factors have been investigated to assess the results of initial management and predict which patients will require further treatment, but there is little agreement between authors as to what variables should be studied. Outcome and the assessment of different management strategies is also contentious. This study describes the assessment of 204 families identified as having at least one child with congenital talipes. Outcome was initially assessed using a subjective scoring system. This was then used to evaluate a number of proposed objective and clinical outcome measures. On the basis of this, an objective system of assessment is proposed using measurement of foot length discrepancy, calf circumference, and range of movement at the ankle. Management was then evaluated objectively showing that in the medium term, a prolonged period of conservative management with Denis Browne splints and boots produced the best outcome. Despite a number of family studies looking at inheritance patterns in CTEV, the mode of genetic transmission remains unclear, and, while a number of environmental factors have been linked to CTEV, scientific methodology, in particular lack of a control group, limits the conclusions which can be drawn. Analysis of 176 family pedigrees demonstrates that CTEV may have an autosomal dominant mode of inheritance in a subgroup of cases. This study also presents the results of a case control study of epidemiological factors in CTEV, demonstrating a link between smoking and CTEV.

The practice of dentistry is physically demanding due to static and dynamic postures sustained daily throughout careers. Previous literature suggests that work-related musculoskeletal disorders (WMSD) are not solely the result of work habits, but also due to the individual, his or her physical makeup, genetics, and personal lifestyle. A 33-question survey was distributed to 1000 general dentists and 2300 orthodontists. The overall prevalence of work-related musculoskeletal disorders was greater among dentists and most often reported as self-limiting. Dentists were three times more likely than orthodontists to report WMSD; females were twice as likely to report WMSD than males; those who sought alternative medical remedies were two times more likely to have WMSD; and practitioners 6-10 years in practice were least likely to report WMSD. Dentists reported sitting in static positions longer than orthodontists; and those with WMSD indicated exercising, stretching, and seeking alternative health remedies more than dentists without WMSD.

Full textAbstract:
Work-related musculoskeletal disorders (WMSDs) continue to present a substantial personal and economic burden. Biomarkers, in providing objective measures of physiological changes, may offer advantages over current tools for WMSD risk assessment. Existing work has identified biomarkers of cartilage and muscle damage, and demonstrated responsiveness to various forms of physical activity and biomechanical loading. Here, three studies were complete to further assess the occupational relevance/utility of three selected biomarkers: Cartilage Oligomeric Matrix Protein (COMP), Interleukin-6 (IL6), and Creatine Kinase (CK). First, the effects of age, obesity, gender, and diurnal variation was investigated. Significant effects of time, age, and gender were evident, as well as some interactive effects, for COMP and CK, but not IL6. Second, biomarker levels were compared between individuals in occupations having relatively high and low WMSD risk. IL6 levels were greater in the high-risk group, while COMP levels demonstrated an oscillatory pattern, and CK levels did not vary between groups. Third, physical demands were imposed on the lumbar spine during a repetitive flexion/extension task, under conditions with different loading and frequency. IL6 levels varied significantly over time and between added load levels, while CK levels varied over time and was influenced by load and frequency. These studies demonstrate important features of biomarkers; that personal confounding factors need to be considered, that select biomarkers may be sensitive to occupational risk factor exposure, and particularly to task parameters in lifting activities involving the lower back. Further, these studies reveal important information concerning the relevance of the selected biomarkers, favorable time points for biomarker collection, and approximate biomarker levels expected between occupations and exposure to common risk factors. These results support the use of biomarkers in occupational settings for assessing exposure and WMSD risk imposed by common risk factors. Sensitivity to exposure levels is an important precursor to risk prediction, however prospective work is needed to verify predictive validity.Ph. D.

Full textAbstract:
Playing related musculoskeletal disorder (PRMD) is common among instrumentalists, professionals, amateurs and music students with a prevalence ranging from 39-47% with an impact on playing and performance. This is synonymous to the prevalence of musculoskeletal disorders among other work population. Risk factors such as lack of warm ups, awkward posture, long playing hours and bad techniques has been consistently indicated as risk factors influencing the incidence of PRMDs among instrumentalists. The aim of this study is to design a warm up programme for instrumentalists. The study population and sample are instrumentalists at the Centre for Performing Arts, University of the Western Cape. A cross sectional study design with a quantitative approach was utilized in this study to determine the prevalence, severity, distribution of PRMDs and its association with quality of life. All the instrumentalists learning or playing a musical instrument of the Centre for Performing Arts was approached to participate in this study. In the first phase of the study, a self administered questionnaire was used to collect data regarding prevalence, distribution and the severity of PRMDs and health related quality of life. The instruments for this study are the standard NORDIC questionnaire for musculoskeletal disorders to determine pain distribution and prevalence, the visual analogue scale to determine the pain severity and the WHOQOL &ndash
BREF, a quality of life questionnaire and an adapted questionnaire to determine the knowledge of instrumentalists about injury prevention strategies. The second phase of the study, a systematic review of evidence was done on the pattern of warm up and practice habits of instrumentalists. The third phase of the study to design the content of the study was done using a Delphi study. The Statistical Package for Social Sciences (SPSS) was used for descriptive and inferential statistics. Chi square was used to determine the association of prevalence, distribution and severity on quality of life. Alpha level was set at 0.05. Ethical clearance and permission to conduct study was sought, written informed consents from participants was sought clearly stating the right to participate and withdraw from study was respected and anonymity and confidentiality was be ensured. The results of the study show that 82.4 % lifetime prevalence and current prevalence of 23.5 % among instrumental musicians in a Centre for Performing Arts. The shoulder (41.2 %), neck (29.4 %) and the wrists and hands (29.4%) are the mostly affected region on the body. The most common symptoms are tightness and soreness. However, the results of the systematic review shows that there is a lack of operational term for warm up in the performing arts and this therefore could be responsible for the variations in the influence of warm up on the prevention of PRMDs. The content of the warm up programme was designed using a Delphi study and stretching and postural awareness were included with musical warm up as part of a regular warm up exercise, although, consensus was not reached on the duration of the warm up programme. Strengthening and conditioning were included to in a different exercise program done three times per week. Education on injury prevention strategies were also included in the programme and the mode of instruction agreed on was active learning and group instruction in classroom. The role of warm up exercise in the prevention of PRMDs using this model could reduce the incidence of PRMDs. However, it is important to note that the programme should be tested in order to determine the overall effect it has on PRMDs.

Full textAbstract:
Introduction: Lower extremity (LE) work-related musculoskeletal disorders (WMSDs) are known to occur with cumulative exposure to occupational and personal risks. The objective of this dissertation study was to find if creating a quantifiable risk detection model for the LE was feasible. The primary product of the literature review conducted for this study resulted in focusing the attention of the model development process onto creating the initial model of the LE for assessing knee disorder risk factors. Literature Review: LE occupational disorders affect numerous industries and thousands of people each year by affecting any one of the musculoskeletal systems deemed susceptible by the occupational and personal risk factors involved. Industries known to be affected tend to have labor intensive job descriptions. Some of the numerous industry examples include mining, manufacturing, firefighting, and carpet laying. Types of WMSDs noticed by the literature include bursitis, osteoarthritis, stress fractures, tissue inflammation, and nerve entrapment. In addition to the occupationally related disorders that may develop, occupationally related discomforts were also taken into consideration by this study. Generally, both the disorders and the discomforts can be traced to either a personal or occupational risk factor or both. Personal risk factors noted by the literature include a person's physical fitness and health history (such as past injuries). Meanwhile, occupational risks can be generalized to physical postures, activities, and even joint angles. Prevalence data over a three year interval (2003-2005) has found that LE WMSDs make up on average approximately 7.5% of all the WMSD cases reported to the US Occupational Safety and Health Administration (OSHA). When the literature is refined to the information pertaining to occupational knee disorders, the mean prevalence percentage of the same three year range is about 5%. Mean cost for knee injuries were found to be $18,495 (for the year between 2003 and 2004). Methodology: Developing a risk model for the knee meant using groups of subject matter experts for model development and task hazard analysis. Sample occupational risk data also needed to be gathered for each of a series of tasks so that the model could be validated. These sample data were collected from a sample aircraft assembly plant of a US aerospace manufacturer. Results: Based on the disorder and risk data found in the literature, a knee risk assessment model was developed to utilize observational, questionnaire, and direct measure data collection methods. The final version of this study's knee model has an inventory of 11 risk factors (8 occupational and 3 personal) each with varying degrees of risk exposure thresholds (e.g., high risk, moderate risk, or minimal risk). For the occupational risk assessment portion of the model, the results of task evaluations include both an occupational risk resultant score (risk score) and a task risk level (safe or hazardous). This set of results is also available for a cumulative (whole day) assessment. The personal risk assessment portion only produces a risk resultant score. Validation of the knee risk model reveals statistically (t (34) = 1.512, p = 0.156), that it is functioning as it should and can decide between hazardous and safe tasks. Additionally, the model is also capable of analyzing tasks as a series of cumulative daily events and providing an occupational and personal risk overview for individuals. Conclusion: While the model proved to be functional to the given sample site and hypothetical situations, further studies are needed outside of the aerospace manufacturing environment to continue testing both the model's validity and applicability to other industrial environments. The iterative adjustments generated for the occupational risk portion of the model (to reduce false positives and negatives) will need additional studies that will further evaluate professional human judgment of knee risk against this model's results. Future investigations must also make subject matter experts aware of the minimal risk levels of this knee risk assessment model so that task observational results are equally comparable. Additional studies are moreover needed to assess the intimate nature between variable interactions; especially multiple model defined minimal risks within a single task.Ph.D.

Full textAbstract:
Although skin disease and musculoskeletal disorders are believed to be common among nursing home workers, to date there have been no coordinated international studies of these occupational issues. Therefore, it was considered appropriate to conduct one of the first cross-cultural investigations of occupational dermatology and ergonomic complaints among nursing home workers in Australia, Japan, South Korea and Taiwan using a standardised methodology. This thesis documents a 4-year investigation of skin disease and musculoskeletal disorders conducted among 465 nursing home staff in Australia, Japan, South Korea and Taiwan. Skin diseases were diagnosed by specialist physicians during medical examinations, while information on musculoskeletal disorders was collected by means of a self-reported questionnaire. There were major differences in both the location and type of skin disease between the 4 groups. Overall, the Australian group suffered a generally higher prevalence of skin disease than in the other three countries investigated, most likely due to their significantly higher rate of sun-induced skin damage. The high prevalence of cutaneous fungal disease seen within the Taiwanese subjects most probably arose from the comparatively higher temperature and relative humidity of Taiwan. Other potentially important skin disease risk factors included previous skin disease and a history of allergy, both of which are consistent with current knowledge. Although musculoskeletal disorders were found to be most prevalent among the Japanese nursing home staff at almost all body sites, the reasons for this are not clear. It may have related to a generally higher musculoskeletal rate, or a higher degree of self-reporting on their questionnaires. Individual MSD risk factors included moving patients, washing patients, working as an assistant nurse and daily alcohol consumption. Interestingly, MSD was found to be a co-factor for current skin disease. Overall, this study indicated that certain occupational health issues consistently affect nursing home staff in the 4 countries, but the prevalence and rank order varies from nation to nation. It was also shown that nursing home work incurs a reasonable degree of risk and that skin disease and musculoskeletal disorders are important occupational issues within these facilities.

Schall, Mark Christopher. "Application of inertial measurement units for directly measuring occupational exposure to non-neutral postures of the low back and shoulder." Diss., University of Iowa, 2014. https://ir.uiowa.edu/etd/2008.
Full textAbstract:
Epidemiological evidence suggests an association between exposure to non-neutral working postures and work-related musculoskeletal disorders (MSDs) of the low back and shoulder. Accurate and precise quantitative estimation of exposure to non-neutral working postures is, therefore, essential for evaluating worker risk, developing and testing ergonomic interventions, and improving worker health and well-being. Current methods used to directly estimate occupational exposure to non-neutral postures may be obtrusive, often lack sufficient portability for field use, and have limited accuracy and precision when used to measure dynamic or complex motions.
Inertial measurement units (IMUs) are emerging instrumentation devices that measure and report an object's orientation and motion characteristics using multiple electromechanical sensors (i.e., accelerometers, gyroscopes, and/or magnetometers). They have been observed to accurately monitor body kinematics over periods of relatively short duration in comparison to laboratory-based optical motion capture systems. Limited research, however, has been performed comparing exposure information obtained with IMUs to exposure information obtained with other field-capable direct measurement exposure assessment methods. Furthermore, insufficient information on the repeatability of IMU-based estimates over a substantial time period (e.g., a full work shift) and inadequate knowledge regarding the effects of different IMU sensor configurations and processing methods on the accuracy and repeatability of estimates of exposure obtained with IMU systems contributes to a lack of their use in epidemiological field studies.
This thesis was designed to address these issues and expand upon the current scientific literature regarding the use of IMU sensors as direct measurement devices for assessing exposure to non-neutral working postures in the field. Chapter I provides a background and justification for the work. Chapter II presents the findings of a laboratory-based, manual material handling study that was performed to compare estimates of thoracolumbar trunk motion obtained with a commercially available IMU system with estimates of thoracolumbar trunk motion obtained with a field-capable reference system, the Lumbar Motion Monitor (LMM). The effects of alternative sensor configurations and processing methods on the agreement between LMM and IMU-based estimates of trunk motion were also explored. Chapter III presents the results of a study performed to evaluate the accuracy and repeatability of estimates of trunk angular displacement and upper arm elevation obtained with the IMU system examined in Chapter II over the course of an eight-hour work shift in both a laboratory and field-based setting. The effects of alternative sensor configurations and processing methods on the accuracy and repeatability of estimates of trunk angular displacement and upper arm elevation obtained with the IMU system were also studied. Chapter IV presents the results of a randomized, repeated measures intervention that demonstrates the utility of the IMU system examined in Chapters II and III as a direct measurement instrument for comparing "ergonomic" and conventional examination equipment commonly used by ophthalmologists. Finally, Chapter V summarizes the major findings, discusses their practical implications, and provides suggestions for future research.

Magister Public Health - MPHBackground: Protecting and promoting health in the workplace is imperative, both for individual employee health and workplace productivity. High rates of workplace injuries, particularly in environments where high levels of physical activity are required, point to the need for effective occupational interventions, minimization of workplace inhibitors that increase the risk of developing musculoskeletal disorders (MSDs), and occupational management checks to reduce the onset of MSDs in the workplace. However, for these measures to be successful, it would be important to identify individual and workplace-related factors associated with the development and duration of MSDs. Aim: To determine potential risk and protective factors associated with MSDs among employees in a workplace where heavy lifting is a key job function.

Full textAbstract:
Prolonged computer work is associated with high rates of neck and shoulder pain symptoms, and as computers have become increasingly more common, it is becoming critical that we develop sustainable interventions targeting this issue. Static muscle contractions for prolonged periods often occur in the neck/shoulder during computer work and may underlie muscle pain development in spite of rather low relative muscle load levels. Causal mechanisms may include a stereotypical recruitment of low threshold motor units (activating type I muscle fibers), characterized by a lack of temporal as well as spatial variation in motor unit recruitment. Based on this theory, although studies have postulated that individuals with chronic neck-shoulder pain will show less variation in muscle activity compared to healthy individuals when engaged in repetitive/monotonous work, this has seldom been verified in empirical studies of actual computer work.
Studies have rarely addressed temporal patterns in muscle activation, even though there is a consensus that temporal activation patterns are important for understanding fatigue and maybe even risks of subsequent musculoskeletal disorders. This study applied exposure variation analysis (EVA) to study differences in temporal patterns of trapezius muscle activity as individuals with and without pain performed computer work. The aims of this study were to: Assess the reliability of EVA to measure variation in trapezius muscle activity in healthy individuals during the performance of computer work; Determine the extent to which healthy subjects differ from those with chronic pain in trapezius muscle activity patterns during computer work, measured using EVA.
Thirteen touch-typing, right-handed participants were recruited in this study (8 healthy; 5 chronic pain). The participants were asked to complete three 10-minute computer tasks (TYPE, CLICK and FORM) in two pacing conditions (self-paced, control-paced), with the healthy group completing two sessions and the pain group completing one. Activation of the upper trapezius muscle was measured using surface electromyography (EMG). EMG data were organized into 5x5 EVA matrices with five amplitude classes (0-6.67, 6.67-20, 20-46.67, 46.67-100, >100% Reference Voluntary Exertion) and five duration classes (0-
1, 1-3, 3-7, 7-15, >15 seconds). EVA marginal distributions (along both amplitude and duration classes) for each EVA class, as well as summary measures (mean and SD) of the marginal sums along each axis were computed. Finally, “resultant” mean and SD across all EVA cells were computed. The reliability in
EVA indices was estimated using intra-class correlation coefficients (ICC), coefficient of variation (CV) and standard error of measurement (SEM), computed from repeated measurements of healthy individuals (aim 1), and EVA indices were compared between groups (aim 2).
Reliability of EVA amplitude marginal sums ranged from moderate to high in the self-paced condition and low to moderate in the control-paced condition. The duration marginal sums were moderate in the self-paced condition and moderate to high in the control-paced condition. The summary measures (means and
SDs) were moderate to high in both the self-paced and control-paced condition. Group comparisons revealed that individuals with chronic pain spent longer durations of work time in higher EVA duration categories, exhibited larger means along the amplitude, duration and in the resultant, and higher EVA SD
in the amplitude and duration axes as compared to the healthy group.
To our knowledge, this is the first study to report on the reliability of EVA applied specifically to computer work. Furthermore, EVA was used to assess differences in muscle activation patterns as individuals with and without chronic pain engaged in computer work. Individuals in the pain group seemed to exhibit prolonged sustained activation of the trapezius muscle to a significantly greater extent than controls, even though they did not experience pain during the performance of the computer tasks (as obtained through self-reports). Thus, these altered muscle recruitment patterns observed in the pain subjects, even in the absence of task-based pain/discomfort, are suggestive of chronic motor control changes occurring in adaptation to pain, and may have implications for the etiology of neck and upper-limb musculoskeletal disorders.Master of Science
This study aims to assess the reliability of exposure variation analysis (EVA) to measure variation in trapezius muscle activity in healthy individuals during the performance of computer work, and to determine the extent to which healthy subjects differ from those with chronic pain in trapezius muscle activity patterns during computer work, measured using EVA. Muscle activation was recorded for eight healthy individual and five suffering from chronic neck-shoulder pain. The data were then categorized into amplitude and continuous time categories, and summary measures of resulting distributions were calculated. These measures were used to assess the reliability of participant responses to computer work of healthy individuals, as well as quantify differences between those with and without chronic pain. We found that individuals with pain activated their neck-shoulder muscles for longer continuous durations than healthy individuals, thus showing an inability to relax their muscles when performing work.

Full textAbstract:
Depression is a common comorbidity in rheumatoid arthritis (RA), yet it may not be adequately recognized during routine clinical care. RA symptoms may confer a risk for depression, and vice versa; depression may affect RA disease activity and response to treatment. The study aims were to compare patient- and physician-reported depression measures, evaluate the temporal bi-directional association between RA disease activity and depressive symptomology, and assess depression as a moderator of RA treatment.
Patients were identified using a national RA registry sample (Consortium of Rheumatology Researchers of North America; CORRONA). Depression prevalence and incidence rates were estimated, and concordance and disagreement using measures reported separately by patients and physicians, as well as baseline cross-sectional associations between RA disease and a history of depression. A survival analysis was conducted to temporally predict the incident onset of self-reported depressive symptoms using the different metrics of RA disease activity. Also, mixed effects models were used to assess prospective changes in RA disease activity by prevalent and incident depressive symptom status. Lastly, logistic regression models compared the likelihood of clinical response to RA treatment during follow-up in those with and without depression when starting biologic disease modifying anti-rheumatic drug (DMARD) therapy.
Patient-reported depression rates were much higher and significantly different from physician based comorbidity estimates. Patient and physician RA disease activity measures were associated with an increased risk for depression onset, but not laboratory-reported serum biomarkers. Similarly, depression was temporally associated with significantly slower rates of decline regarding every patient-reported disease activity measure, some physician-reported metrics, but not acute phase reactants. Moreover, there was a significantly lower probability of achieving clinical remission among those with depression on a biologic DMARD after 6 months and an analogous effect at 12-months that was slightly lower in magnitude, which did not reach statistical significance.
Rheumatologists under-reported the occurrence of prevalent and incident depressive symptoms, and thus are likely unaware of its presence in their RA patients. Further, the results suggest the bi-directional effects between these conditions are related to the cognitive and behavioral aspects of depression and their interactions with disease activity, rather than shared immunological mechanisms in the context of cell-mediated immunity. When also considering the impact on clinical response to biologic DMARDS, the findings collectively imply that rheumatologists must address any challenges due to depression to provide the best care to their patients.

Full textAbstract:
BACKGROUND AND SIGNIFICANCE. Various studies have identified physical risk factors for musculoskeletal disorders (MSDs) associated with hand harvesting of crops, due to repetitive motions, lifting or carrying of heavy loads, and working in flexed trunk postures. A paucity of research exists on ergonomic risks to tomato farmworkers. The available studies have estimated risk based on self-reports of injury and semi-quantitative measures.
METHODS. A partnership between East Tennessee State University (ETSU) and a migrant health center (Rural Medical Services) has identified some of the occupational health needs of this population. With the aid of surface electromyography (sEMG), an objective-quantitative tool, a more refined understanding of ergonomic health risks for this population will be developed. The purpose of this study is to evaluate the muscle load and fatigue induced on the anterior deltoid and upper trapezius muscles during three tasks: driving stakes into the ground, tying of tomatoes to stakes, and hoisting of a 35-pound bucket full of tomatoes. Space for a mock test plot, where the study will be conducted, is available at the ETSU’s Valleybrook facility. Muscle activity recordings will be obtained from 15 tomato farmworkers. Spectral analysis and the amplitude probability distribution function (APDF) will be used to assess fatigue and muscle load respectively. A repeated measures ANOVA will be employed in the study.
ANTICIPATED RESULTS. Findings of this study should show that localized muscle loading increases muscle fatigue. Neuromuscular demand should vary, depending on the type of task performed. Stake pounding may show a higher neuromuscular demand than the other tasks.
AIM 1. Evaluate the magnitude of muscle activity during three simulated tomato-field tasks and measure the intensity of movement during the stake pounding task.
AIM 2. Compare estimates of muscle fatigue and muscle load induced on the anterior deltoid and upper trapezius muscles during three simulated tomato-field tasks.

Full textAbstract:
This study is a subset of a larger body of research that examined shoulder time to fatigue during overhead work in an attempt to reduce the prevalence and impact of work-related musculoskeletal problems in the shoulder associated with overhead work, particularly during automobile assembly. Existing evidence suggests that shoulder injuries are diverse in terms of tissues affected and symptoms presented. Furthermore, the cause of these injuries is multifactorial. The work presented here assumes that musculoskeletal injuries of the shoulder mechanism are at least related to, if not caused by, fatigue localized to the shoulder musculature. While the exact relationship between fatigue and injury has not been clearly established, there is consensus among researchers that fatigue plays and important role. Muscular fatigue, therefore, is viewed as a surrogate measure of risk, and task design to avoid fatigue is seen as a rational method to minimize this risk.
An experiment to determine the effects of tool weight on shoulder fatigue and performance during overhead work with work/rest cycles was performed. Times to fatigue were derived based on dependent measures including total task duration, controlled maximum muscle contractions, subjective ratings based on Borg's CR-10 RPE scale, electromyogram behavior (MdPF), and hand force performance measures. Experimental findings indicated that duty cycle (percentage of total task cycle time spent working) significantly affected task duration (p<0.0001), changes in maximum voluntary contraction values for the infraspinatus (p<0.05), and the minimum time for any shoulder muscle to fatigue as determined by changes in the EMG power spectrum (p<0.05). Time to fatigue for the mid deltoid as determined by changes in the median frequency of the EMG power spectrum was shown to change significantly (p<0.05) with change in tool weight. Large intersubject variation was observed for the dependent measures, which showed subjects experiencing different levels of fatigue while performing the same task. Limitations of the study and recommendations for future direction are also discussed.Master of Science

ABSTRACT
The association between biomechanical risks and musculoskeletal disorders in agriculture is well known, but within the dairy industry, the literature is still sparse on the precise exposure. This project, addressed at fulfilling some of the knowledge gaps and at creating exposure and risk Profiles for specific milking parlor activities, has been conducted in order to:
a) estimating the effects on wrists of parlors’ workers of repetitive motions, pointing out an ultrasonography approach;
b) developing screening tools useful in the periodical health surveillance of dairy workers to detect early wrists’ changes;
c) compare the levels of muscle activation in milking work between large herd and small herd operations;
d) define preventive criteria addressed at risk control in dairy activities.
The project has been carried out in 4 single studies, In the first, 14 parlor workers and 22 controls were studied through a) personal anamnesis collection; b) wrists ultrasonography; c) upper limb clinical evaluation. The study confirmed the wrist as target of biomechanical risk factors and identified the two wrist’s acoustic window characterized by the highest predictive value for wrist’s structure alteration. The second study was conducted on 40 dairy workers, studied with the approach defined in the first study. Main objective was evaluating the levels of concordance between questionnaire results and clinical and ultrasound evidences. The questionnaire showed a high level of specificity (82.15%. C.I.95%: 62.4%-93.2%) if compared with clinical investigation outcomes and/or ultrasound findings. The study allowed us to conclude that 1) the administration of a questionnaire can be predictive of early wrist’s changes. 2) The questionnaire created is adequate for the periodical screening of parlor workers’ wrist. The same population was involved in the third study, addressed to defining risk Profiles of wrist biomechanical overload of parlor workers. Anthropometric measurements, personal and occupational variables, surface electromyography data of dominant upper limb muscles were collected to define activation profiles. Strain Index for each single milking subtask (pre dipping, wiping/stripping, attaching, post dipping) was evaluated. The study defined three main risk profiles: low, medium and high risk. Main risk determinants were: characteristics of the workstation, organization of the work, milking routine. We concluded that organization of the milking routine, and cluster weight not major than 2.4 Kg are useful interventions to be carried out. The fourth study was conducted to compare upper limb muscle activity between US and Italian industrialized Dairy operations. Twenty-nine workers were recruited from large herd US herd (>1000 head) dairies and 39 from small herd Italian dairies. Surface electromyography was used to assess muscle exertion levels of all workers, measuring intensity, expressed as root mean square of the raw signal, amplitude probability distribution function percentiles, and the percent muscular rest of the interested muscles. The statistical analyses indicated significantly greater average muscle activity during milking tasks among large herd versus small herd dairy workers in the biceps brachii (p<0.001), upper trapezius (p=0.002), and the wrist flexors (p<0.001) between the two dairy types. The final study demonstrated that, independently from the size and the country, parlor activities pose significant biomechanical wrist risk.

Full textAbstract:
A healthy posture protects the body-supporting functions and prevents injuries by maintaining balance. Literature in performing arts medicine suggests that posture is an important component to prevent piano-playing related injuries. However, no known research studies have quantified, characterized, and compared pianists' sitting postures. The purpose of this study was to explore the relationship between playing postures and perceived pain among pianists. This study applied innovative approach using qualitative and quantitative methods, combined with three-dimensional motion captured technology. To examine risk factors related pianists' postures, three-dimensional motion-capture cameras recorded approximate 40 pianists' postures in various situations; data recordings were combined with a statistical method to investigate pain-posture correlations. Results reveal that the degrees of head-neck or body tilt angles are the tendency of risk factors for piano-playing related pain. Results from this study may have multiple practical implications among which are: (1) a risk factor pain, injury index, or indicator (2) a performance habits profile and (3) practice guide to prevention of piano-playing related musculoskeletal disorders.

Performance related musculoskeletal disorders (PRMDs) are a frequent reality for practicing musicians. Many aspects of the bassoon make bassoon players particularly susceptible to PRMDs. This thesis explored the prevalence of PRMDs among bassoon players and assessed the frequency, types, and locations of PRMDs. Also identified were treatments used for PRMDs, contributing factors to PRMD development, and the perceptions of the bassoon community regarding PRMDs. The International Bassoonist Questionnaire was distributed via the World Wide Web (n = 166, 58% male, 42% female). Eighty-six percent of bassoon players reported PRMDs. Pain was the most common PRMD symptom reported (78%). Females reported PRMDs (96%) more frequently than males (78%). Younger bassoon players reported more PRMDs. Most bassoon players (88%) were attempting to treat their PRMDs. The most common self-administered treatments were rest (60%) and reducing playing time (53%). Bassoonists attributed the cause of PRMDs to “long hours of practice” and “sudden increase in playing time.” Bassoon players felt strongly that the medical profession did not know how to treat a bassoon related injury. They believed that a knowledgeable teacher was the best resource against the onset of PRMDs even though technical aspects of playing were not identified as significant contributors to PRMDs. The bassoon playing population needs more information about PRMDs in order to develop treatment and prevention strategies.

Full textAbstract:
The musculoskeletal disorders have significant health care, social and economic consequences in the factories nowadays. One of the most promising possible solutions is the use of exoskeletons in the workstations. Exoskeletons are assistive wearable robotics connected to the body of a person, which aims to give mechanical power or mobility to the user (Wang, Ikuma, Hondzinski, & de Queiroz, 2017). The objective of this project is to create a realistic CAD model of a passive exoskeleton which will be used in future research to analyse the behaviour of the workers in a virtual environment with and without the exoskeleton. This model will be a virtual representation of the exoskeleton EKSOVest which has been designed to support these workers who have to realize overhead tasks. This virtual representation will be carried out in PTC CREO and exported to IPS IMMA in order to check the viability of this model. To achieve a realistic model, the exoskeleton should have the same characteristics than the real exoskeleton. The objectives of this project will be defined for these characteristics, which are part creation, mechanisms, forces simulation, and parametrization. The parts and the mechanisms will be created and defined in PTC CREO with the same dimensions and behaviour as the real exoskeleton. Furthermore, this report will be focussed mainly in force simulation and the parametrization. The forces of the EKSOVest are generated by two different spring and by a high-pressure spring. To simulate these forces, the equation of these springs will be obtained and introduced in PTC CREO. These equations will be obtained through the regression of a set of points, which will be obtained from the real exoskeleton using a dynamometer. The parametrization will be carried out with the objective to make the virtual model adaptable for every type of mannequins. This parametrization will modify the length of the exoskeleton’s spine bar and the distance between the mechanical arms. These distances will be adapted according to the mannequin’s measures which will be introduced by the user. The measures that have to be introduced by the user are shoulder height, liac spine height, and chest width. In conclusion, it can be said that the regression of the springs obtained are an accurate result which can imitate quite well the forces of this exoskeleton. Furthermore, the results of the parametrization allow the exoskeleton adaptable to any type of dimensions that the mannequin could have. The final model obtained has been exported to IPS IMMA and implemented in a mannequin.

Conclusiones: El presente estudio logró determinar la relación entre los factores de salud asociados a la calidad de vida y encontró asociación con la presencia de dolor por trastorno musculo esquelético, tiempo de bombero, edad y sexo. No se encontró asociación en los factores, obesidad, hábito de fumar y nivel de actividad física.Quality of life is perceived as the physical, mental and emotional balance of the person, which can be influenced by different factors such as the presence of pain due to musculoskeletal disorders, obesity, level of physical activity, and smoking habits. In the population of the General Volunteer Fire Department of Peru these factors can be favorable or can decrease the quality of life. Objective: Verify the association between health factors and quality of life in the General Volunteer Fire Department of Peru. Methods: A cross-sectional, observational and analytical study was carried out on the staff of the General Volunteer Fire Department of Peru from Lima-Peru, XXV Departmental Lima-North, XXIV Departmental Command Lima-South, and the IV Departmental Command Lima. The SF-36 version 1 questionnaire was used to measure the quality of life. The standardized Nordic questionnaire was used to measure the presence of pain due to musculoskeletal disorders, the International Physical Activity Questionnaire (IPAQ) to measure the level of physical activity, and abdominal circumference was measured to determine the presence of obesity. A power analysis was performed for the sample studied. The T-Student was used for the analysis of the numerical variables. Anova was used for the analysis of variances and comparing the means of the response variable. Results: 167 people participated, the average age was 37.5 ± 11.3 years, 140 (83.8%) were male. It was found that 31% smoke cigarettes. 141 (83.9%) have abdominal obesity, but more than half had a high level of physical activity (57.7%). Within the 8 dimensions of quality of life on the SF-36, no scores below 70% were observed. 159 (95.2%) reported to have had musculoskeletal pain at some time in their life, while 122 (73.9%) reported having pain during the last year and 99 (61.1%) during the last four weeks. Age was associated with the fatigue dimension (p = 0.014) and emotional well-being (p = 0.002). The sex variable was associated with the dimension limitation due to physical health (p = 0.031); fatigue (p = 0.040); and general health (p = 0.047) and the male group was the one with the highest scores. The service time as a firefighter affected dimensions such as physical functioning (p = 0.013); limitation due to physical health (p = 0.007); social functioning (p = 0.006) and pain (p = 0.012). Having had pain at some time in life was associated with the dimensions of fatigue (p = 0.003), social functioning (p = 0.044), and general health (p = 0.010). While pain reported in the last year was also associated with those same dimensions and with the pain dimension in the SF-36 (p = 0.001). Finally, the pain report in the last month was associated with all the mentioned dimensions and with the physical functioning (p = 0.009). The variables of obesity, smoking and physical activity had no association with any of the 8 dimensions of quality of life. Conclusions: The present study was able to determine the relationship between health factors and with quality of life. An association was found between presence of pain due to musculoskeletal disorders, time as a firefighter, age and sex. No association was found in factors of obesity, smoking and level of physical activity.

Dans le cadre professionnel, les maladies professionnelles telles que les troubles musculo-squelettiques et les maladies psychiques constituent la première cause d'entrée dans le régime d'invalidité en France. Leur singularisme se situe dans leur étiologie complexe qui échappe au système d'indemnisation. Ces maladies dont le travail est une cause mais ne peut être avec certitude la cause ne sont quasiment pas prises en charge.Leur réparation se fonde encore principalement sur une loi compromissoire entre patronat et salariés centenaire, sur laquelle se sont empilés des mécanismes réparatoires législatifs et jurisprudentiels, et leur prévention nécessiterait un bouleversement dans le rapport au travail. Dans la fonction publique, cette mauvaise prise en charge n'est pas sans créer des disparités entre agents, selon leur régime statutaire ou la reconnaissance effective de la maladie au service.Le système de réparation actuel qui laisse à la charge de la sécurité sociale des maladies pourtant liées au travail ne peut perdurer. Cependant de nouvelles modalités d'indemnisation ne sont possibles que si le coût est supportable. Or l'inexistence de chiffres permettant d'estimer le nombre de maladies reconnues ou sous-déclarées et de ce fait la part des maladies multifactorielles, rend l'estimation de ce coût impossible.La base de données (année 2008) qui a été constituée dans ce travail permet d'évaluer le nombre d'agents touchés par une maladie multifactorielle et laisse à penser que seule une réparation partielle assortie d'une prévention incitative est susceptible de prendre en charge de manière acceptable et pérenne les maladies multifactorielles dans la fonction publiqueIn the working environment, multifactorial disorders such as musculoskeletal and mental disorders are the main cause of officially recognized disability in France. Their particularity lies in their complex etiology, which makes claims for compensation difficult. They can be caused in part by working conditions, but other factors are involved, with no single clearly identifiable cause. Their compensation mechanisms are mainly based on hundred-year-old employment arbitration law, to which other legislative and jurisprudential compensation mechanisms have been added. These disorders can only be prevented by a complex shift in attitudes to work and in the perception of proper working conditions. For civil servants, the current system causes disparities between agents, due to differences in their legal status and recognition of the disorder in each department.Under the current system of compensation, the cost of these work-related disorders is covered by social security, which is untenable, but any new form of compensation must be cost-efficient. However, as there are no figures available to estimate the number of recognised occupational disorders and hence the proportion of multifactorial diseases, it is not possible to estimate their cost. From the data collected in this study for the year 2008 it is possible to calculate the number of agents affected by multifactorial diseases. The results indicate that the only long-term and appropriate way to deal with this problem in the civil service is through partial compensation combined with incentives to prevent these disorders

Full textAbstract:
Musculoskeletal disorders are among the most important health problem affecting the quality of life and contributing to a high burden on healthcare systems worldwide. Understanding the molecular mechanisms underlying these disorders is crucial for the development of efficient treatments. In this thesis, musculoskeletal disorders including muscle wasting, bone loss and cartilage deformation have been studied using systems biology approaches. Muscle wasting occurring as a systemic effect in COPD patients has been investigated with an integrative network inference approach. This work has lead to a model describing the relationship between muscle molecular and physiological response to training and systemic inflammatory mediators. This model has shown for the first time that oxygen dependent changes in the expression of epigenetic modifiers and not chronic inflammation may be causally linked to muscle dysfunction. Bone and cartilage deformation observed in ageing, arthritis and multiple myeloma (MM) patients have also been investigated by using a novel modularization approach developed within this thesis. This methodology allows integration of multi-level dataset with large interaction networks. It aims to identify sub-networks with genes differentially expressed between experimental conditions that are co-regulated across samples in different biological systems. This study has identified several potential key players such as Myc, DUSP6 and components of Notch that could enhance osteogenic differentiation in MM patients. In conclusion, this thesis present the effectiveness of systems biology approaches in understanding complex diseases and these approaches could be applied for studying other systems and datasets.

Full textAbstract:
The aims of the work within this thesis were to i) establish the prevalence of musculoskeletal disorders among hospital based nurses and physiotherapists and to establish both perceived and possible causes for these disorders, ii) obtain clinical diagnoses and prognoses of nurses and physiotherapy staff attending an Occupational Health Department, iii) to establish which occupational tasks have the greatest potential to cause musculoskeletal disorders and iv) to investigate the effects of simulated nursing tasks and a modified porters' work-rest schedule on spinal shrinkage. In the epidemiological study the annual prevalence of all musculoskeletal disorders was estimated for nurses and physiotherapists in combination as 49%. The point prevalence was 20.7%. The anatomical area most affected was the lower back, buttocks, upper leg area. In total, musculoskeletal disorders accounted for 19% of all absences from work from all respondents within the previous year. Of those staff attending the Occupational Health Department, the main anatomical area affected by musculoskeletal disorders was, again, the back. Whilst a clinical diagnosis could be given to some patients, others were categorised as having 'low-back pain' indicating the often idiopathic nature of the symptoms. Time off work was often extensive and some staff members were retired from their profession as a direct result of their disorder. Patient handling was cited as the major perceived cause of the musculoskeletal disorders experienced. This variable was not significantly associated with the presence of musculoskeletal disorders in a logistic regression analysis. It is likely that all aspects of nursing and physiotherapy require some degree of manual handling and the category as a whole is too broad to enable an association with the presence or absence of a musculoskeletal disorder to be identified. Factors found to be associated with the presence of a musculoskeletal disorder or back pain were the specialty in which the individual worked, the age of the individual, whether physiotherapists' work regularly required the maintenance of stooped postures, the percentage time the individuals spent on their feet during a shift and the psychological variables of work pressure, happiness at work and job aspirations/motivations. The direction of causality for these variables was not established. An ergonomic risk assessment indicated that the tasks with the highest risk potential were manual handling tasks and those involving a static hold/standing of a patient. Manual handling had a high risk score, mainly because of the awkward, non-optimum postures staff were forced to adopt to perform the task. Tasks requiring static flexions scored highly because they were often performed alone and the flexion was maintained for some time. The task's score was also related to other external factors. The final set of studies considered the influence of nurses' and porters' tasks on spinal shrinkage. During a 4-hour simulation of nursing tasks, spinal shrinkage was significantly less with a 20-min seated break than with a 20-min standing break. Ensuring nurses take a 20-min seated break during each shift has the potential to reduce the prevalence of back-pain. A modified work-rest schedule for hospital porters did not have any effect on spinal shrinkage during a 4-hour simulation of occupational activities. The high prevalence of back pain among this group can not be reduced by adopting the modified work-rest schedule. A model detailing the causal factors for musculoskeletal disorders and low-back pain in nurses and physiotherapists has been proposed based on current findings within this thesis. This ergonomic model requires validation in future work.

Full textAbstract:
The overall aim of this thesis was to gain new knowledge of factors and interventions that improve work ability and return to work (RTW) among women on long-term sick leave from human service organizations (HSOs). The specific aims of the studies were: to evaluate the associations between the self-rated Work Ability Index (WAI) and Work Ability Score (WAS), and the relationship with prospective sick leave, symptoms, and health (Paper I); to investigate whether intervention with myofeedback training or intensive muscular strength training could decrease pain and increase work ability among women with neck pain (Paper II); to examine the associations between workplace rehabilitation and the combination of supportive conditions at work with work ability and RTW over time (Paper III); and to explore experiences, views, and strategies in the rehabilitation process for RTW (Paper IV). This thesis is based on a prospective cohort study (n=324) and a randomized controlled study (RCT) (n=60, participants with neck pain). Both quantitative and qualitative methods were used. The data collection consisted of questionnaires, laboratory-observed data, register-based data, and interviews. The results showed a very strong association between WAI and WAS, and results predicted future sick leave degree, health-related quality of life, vitality, neck pain, self-rated general health, self-rated mental health, behavioral stress, and current stress (Paper I). In the RCT (Paper II), individuals in the myofeedback intervention group increased their vitality and work ability over time and individuals in the intensive musculoskeletal strength training group increased their WAI, WAS, and mental health over time. WAI, WAS, and RTW increased over time among individuals provided with workplace rehabilitation and supportive conditions at work (Paper III) such as a sense of feeling welcome back at work, influence at work, possibilities for development, degree of freedom at work, meaning of work, quality of leadership, social support, sense of community, and work satisfaction. Women described (Paper IV) how they were striving to work and how they had different views, strategies, and approaches in the rehabilitation process for RTW. They expressed a desire to work, their goals for work, and their wishes for work. In the rehabilitation process for RTW they described their interaction with stakeholders as either controlling the interaction or struggling in the interaction. They described strategies to cope with RTW in terms of yo-yo (fluctuating) working: yo-yo working as a strategy or yo-yo working as a consequence. This thesis identifies factors of importance in improving work ability and RTW among women on long-term sick leave from HSOs. For women with neck pain, the intervention study showed feasibility of the intervention and demonstrated improved work ability and decreased pain (Paper II). The intensive muscular strength training program, which is easy for the individual to learn and perform at home, was associated with increased work ability. The results regarding rehabilitation highlight the importance of integrating workplace rehabilitation with supportive conditions at work to increase work ability and improve RTW (Paper III). Women expressed that they were striving to work and that they wanted to work (Paper IV). These women were “going in and out” of work participation (yo-yo working) as a way to handle the rehabilitation process. For assessing the status and progress of work ability among women on long-term sick leave, the single-question WAS may be used as a compliment to the full WAI as a simple indicator (Paper I).Akademisk avhandling som för avläggande av medicine doktorsexamen vid Sahlgrenska akademin, Göteborgs universitet, kommer att offentligen försvaras i hörsal Hamberger, Medicinaregatan 16 A, Göteborg, måndagen den 6 oktober 2014, klockan 09.00

Full textAbstract:
The rising prevalence and burden of musculoskeletal disorders (MSDs) is a major health concern, affecting quality of life and causing an economic burden to the individual as well as society as a whole. Integrative medicine (IM), a complex intervention which includes complementary and alternative medicine (CAM) and conventional medicine, emphasising a holistic approach and patient-practitioner relationship, is a popular option for people with MSDs. The Medical Research Council’s (MRC) framework for evaluating complex interventions was used to explore IM for MSDs and to provide future guidance. The aims of this research study were to develop a theoretical understanding of IM; and to determine the feasibility of carrying out a mixed methods study of IM for MSDs in the UK. For the initial development stage of the MRC framework, a mixed methods review consisting of a mapping review, a systematic review, and a narrative review was performed to develop a theoretical understanding of IM for MSDs. There was promising evidence for integrative treatments provided for low back pain and patients perceived benefits in receiving CAM for their MSDs. However, the components identified in the review as essential in IM were rarely discussed or reported in research. The lack of a standard definition of IM and an absence of guidelines for reporting IM has hindered the process of developing its evidence base. Identification of authentic IM research was challenging, and evidence on IM for MSDs remains inadequate. In particular, no research studies explored IM as a package of care for MSDs in a secondary National Health Service (NHS) setting in the United Kingdom (UK). As part of the second stage of the MRC framework, the feasibility stage, a mixed methods research study was conducted to assess the feasibility of evaluating IM for MSDs at the Royal London Hospital for Integrated Medicine (RLHIM). The results of this mixed methods study of 60 patients followed up over 12 months suggested that the approach was generally feasible. Feasibility was reflected in four aspects: 1). Integrative treatments potentially produced moderate pain relief and improved health related quality of life (HRQoL) at four months which was sustained at 12 months, 2). Patients’ general acceptability of treatment was good, 3). Patients demanded integrative treatment, and 4). Overall research design was feasible with patients reporting positive experiences by participating in the research study. Issues and challenges were identified in the research procedure, including difficulties identifying and recruiting eligible patients, working with busy NHS practitioners, and failure of accessing unit cost data from the hospital. These issues need to be considered in future IM research. In addition, patients suggested particular outcome measures, and a narrative approach was preferred. An IM model was hypothesised from the findings of this research study which represented patients’ perception of good IM care. This research study is the first step in evaluating IM for MSDs. It has provided essential information needed to move the evidence base for IM; and provided original data on the feasibility and practicality of conducting the study. Following the next stage of the MRC framework, future research evaluating IM effectiveness, exploring the potential interaction between the components of the model, and whether these components were associated with the overall effects of IM, using a mixed methods design under a pragmatic approach is warranted.

Full textAbstract:
Le tendon d'Achille est composé de trois sous-tendons qui proviennent chacun d'un chef du triceps surae: gastrocnemius medialis, gastrocnemius lateralis, et soleus. Une distribution non optimale de la contrainte imposée au tendon d'Achille contribuerait au développement de la tendinopathie d'Achille. D’autre part, la distribution des contraintes sur le tendon d'Achille est en partie déterminée par la distribution de la force entre les chefs des triceps surae. L'objectif général de cette thèse était d’étudier le rôle de la coordination musculaire (définie comme la distribution de force entre les muscles) dans le développement d’une tendinopathie d'Achille. Les forces musculaires de chaque muscle ont été estimées à partir de l'activation, du volume et de l'architecture musculaires. Les résultats ont montré que (i) la distribution de l’activation musculaire dans le triceps surae est robuste dans le temps, et varie considérablement d'un individu à l'autre; (ii) il existe une corrélation positive significative entre la distribution de la surface de section transversale physiologique et la distribution de l'activation au sein des gastrocnemii; (iii) le gastrocnemius lateralis contribue significativement moins à la force totale produite par le triceps sural chez les personnes atteintes de tendinopathie d'Achille par rapport aux contrôles. L’altération de la coordination musculaire pourrait être une cause, comme elle pourrait être une conséquence de la tendinopathie d’AchilleThe Achilles tendon is made of three subtendons that each arises from a different head of the triceps surae: gastrocnemius medialis, gastrocnemius lateralis and soleus. Non-optimal distribution of load within Achilles tendon would contribute to the development of Achilles tendinopathy. Moreover, there is evidence that the distribution of load or strain within the Achilles tendon is partly determined by the distribution of force among the heads of the triceps surae. The overall aim of this thesis was to provide a deeper understanding of the role of muscle coordination (i.e. the distribution of force among muscles) on the development of Achilles tendinopathy. Individual muscle forces were estimated from muscle activation, volume and architecture. Results showed that (i) the distribution of activation among triceps surae is robust between days, and varies greatly between individuals; (ii) there is a significant positive correlation between the distribution of physiological cross-sectional area and the distribution of activation among gastrocnemii; (iii) muscle coordination among the triceps surae differs in people with Achilles tendinopathy compared with controls, with the gastrocnemius lateralis contributing significantly less to total triceps surae force in people with Achilles tendinopathy. Whether this altered strategy is a cause or a consequence of Achilles tendinopathy should be further explored

Musculoskeletal disorder is one of the most common health problems among nursing personnel in European and the United States. Its origin is multi-factorial. The objective of this study is to assess the prevalence of musculoskeletal disorders and to find potential occupational risk factors. A cross- sectional survey was conducted in a total of 300 nurses from one university hospital. The used method is ergonomic job analysis of nurse activities in the hospital. There are three steps: 1) questionnaire survey, 2) ergonomic job analysis, 3) musculoskeletal disorders (MSDs) checklist analysis. The results of questionnaire analysis showed Musculoskeletal disorder prevalence of shoulder (23.4%), neck (18.3%), arm (11.0%), low back (39.0%), leg (34.5%) was very serious among nursing personnel. Both ergonomics job analysis and MSDs checklist analysis showed low back and lower limb symptoms of nursing staffs in surgery prepare room and central supply service. Basing on the results, increasing ergonomic knowledge of nursing staffs and keeping attention to musculoskeletal disorders is required. Manual material handling and layout redesign in both surgery prepare and central supply service rooms are required to decrease prevalence musculoskeletal disorders.

In recent years, as Hospital Accreditation developed and with it the management idea of a hospital that pay more attention to the patients and medical care quality. In the past years, many researches discussed about ergonomic hazards for the nursing staff but few for medical records Staffs. So, the aim of this study is to do ergonomic hazards analysis of medical records Staffs and propose improvements. The subjects of this study were 209 from eleven hospitals. Three parts of this study were: 1) collecting musculoskeletal disorder data by a questionnaire, 2) investigate high risk task by job analysis and 3) using ergonomics checklist (BRIEF) and biomechanics instruments to do ergonomic hazards analysis. The results of questionnaire showed higher musculoskeletal disorder prevalence were in shoulder (88%), neck (75%) and wrist (62%). The result of BRIEF showed higher risks in the segments of shoulder, neck and hand/wrist. Based on the data of questionnaire, the result of BRIEF was consistency. By biomechanics assessments, the L5/S1 disc of spine has been found over loading the action level when subjects performed some lifting tasks. By comparing the biceps and triceps activities of different height, we found they are not significant. The results showed that the tasks of medical records Staffs may occur musculoskeletal disorder. The recommendations to prevent the ergonomics hazards of the workers were adjusting the distribution of rest time and manpower from administration, revising the posture of the task and making job principle and enhance ergonomic knowledge to do their job correctly by training.

Background：Musculoskeletal disorders are one of occupational injury disease for medical staff, but fewer studies discuss the main occupations about medical technologist. They often work for a long time or maintain the position of the poor ergonomic. Therefore, the issue medical technologists have a higher risk of musculoskeletal disease than the public is worth investigated. Data from the Taiwan National Health Insurance Research Database were used to analyze the risk of musculoskeletal disorder and medical utilization between medical technologists and the public. Method：The study data from the Taiwan National Health Insurance Research Database t is about Medical Technologist’s Medical Utilization. Comparison of medical technologists and the public about age and gender were selected data base ratio 1:1 in 2011. The data information included Carpal tunnel syndrome, ankylosing spondylitis, degenerative myelopathy, spondylolisthesis, backache, lumbago-sciatica, osteitis of shoulder region syndrome, epicondylitis, digitus recellens and radial styloid tenosynovitis. Results：Total medical technologists were 7,982 suffering from musculoskeletal disorders have medical treatment for the 863 people that proportion of occupied 10 % nearly. The average number of musculoskeletal disorders per person per year was 0.29± 1.36 times. Besides, the average cost of outpatient clinics was 204.06 ± 1050.9 dollars. Musculoskeletal disease in low back pain 41.5% and back pain 20.5% of the highest rate. We controlled influencing factors about gender, age, insured amount and insured business group utilizing negative binomial regression analysis. Finally, we were finding that medical technologists suffering from musculoskeletal disorders for medical use significantly higher than the general public. Conclusion：Medical technologists in the musculoskeletal disorders for medical treatment is indeed high. Therefore, they should pay attention to its work on the posture of ergonomics and occupational injury prevention.

Indiana University-Purdue University Indianapolis (IUPUI)Symptoms of post-traumatic stress disorder (PTSD) are a common comorbidity in veterans seeking treatment of chronic musculoskeletal pain (CMP). However, little is known regarding the mutual influence of PTSD and CMP in this population. Using cross-sectional and longitudinal data from a randomized clinical trial evaluating a stepped care intervention for CMP in Iraq/Afghanistan veterans (ESCAPE), this dissertation examined the relationships between PTSD and CMP along with other factors including depression, anxiety, catastrophizing and health-related quality of life. The Classification and Regression Tree (CART) analysis was conducted to identify key factors associated with baseline PTSD besides CMP severity. A series of statistical analyses including logistical regression analysis, mixed model repeated measure analysis, confirmatory factor analysis and cross-lagged panel analysis via structural equation modeling were conducted to test five competing models of PTSD symptom clusters, and to examine the mutual influences of PTSD symptom clusters and CMP outcomes. Results showed baseline pain intensity and pain disability predicted PTSD at 9 months. And baseline PTSD predicted improvement of pain disability at 9 months. Moreover, direct relationships were found between PTSD and the disability component of CMP, and indirect relationships were found between PTSD, CMP and CMP components (intensity and disability) mediated by depression, anxiety and pain catastrophizing. Finally, the coexistence of PTSD and more severe pain was associated with worse SF-36 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores. Together these findings provided empirical support for the mutual maintenance theory.

Objective: This study aimed to examine the musculoskeletal injuries of nurses and the related risk factors. Baseline Risk Identification of Ergonomic Factors Checklist was applied to assess "the human factors engineering exposure of nurses" as well as to investigate the relationship between the work-related factors and musculoskeletal diseases. Object: With a cross-sectional research method, this study involved 233 nurses at a certain Regional Hospital of the central Taiwan. The participants in each unit were classified according to their work assignment. Methods: The data were collected by using Noridc Musculoskeletal Questionnaire (NMQ), a work pressure survey, a consciously fatigue scale questionnaire and a Baseline Risk Identification of Ergonomic Factors (BRIEF) checklist. The nurses responded to the questionnaires, with SPSS analysis and discussion. The data were filed and analyzed with SPSS 22.0. Results: The results were summarized as follows: 1.Among the three different categories of nurses , there are statistically significant differences in gender, age, body mass index, marital status, educational attainment, and exercise habits (P <.05). 2.Overall, the nurses prevalence of musculoskeletal discomfort was 34.18 %of the findings, the most serious was shoulder pain(78.1%), neck pain(70.4%) and lower back pain(50.2%). 3.Overall, the prevalence of musculoskeletal discomfort was roughly the same. There was no significant difference between the different groups. In addition, the "less limbs problem" was indicated as a common point. 4.The average daily working hours of nurses are 158 minutes for working on the computer, 36.8 minutes for injections and blood draw and 34.7 minutes for pushing work car. Analysis of 14 kinds of nursing work indicated a significant correlation (p<.05) between the musculoskeletal discomfort and such nursing work as computer work, changing bit, moving patients, blood pressure, blood injections, sliding work car and dressing musculoskeletal discomfort. The result implies that the hidden hazard factors might lie in the above mentioned work assignments. Conclusion: The results suggested that the chance of occurrence of musculoskeletal discomfort in nurses is quite high, and different work assignment will result in different type of discomfort. This study recommends that hospital supervisor should provide education and training for the nurses, according to their different nature of work. By using early detection of hazards in the hospital environment and through human factors engineering to improve proper posture and method of work, this study might help the nurses to prevent or reduce the risk of musculoskeletal disorders.

Work-related musculoskeletal disorder (WMSD) is a very serious occupational safety and health problem in industrialized countries, it affects not only the health of workers resulting in injury and disability, but also causes the cost in work absenteeism, medical expense, productivity loss to industry, and increases social cost. In order to prevent WMSD, scholars generally agreed that the five risk factors of WMSD –awkward posture, over-exertion, high repetition, vibration, and oppression of organization should be eliminated or reduced with ergonomics method, and through promotion of the organizations to implement in corporation and workplace. This thesis introduced the MSDS prevention systems of the U.S., Canada, Finland, Germany and Taiwan, and provided information to help strengthening the prevention system of Taiwan. In terms of strategy, all the prevention systems of these countries are basically formed by three organizations, such as government for law making and enforcement, research institutions provide prevention directives and technical support, and promotion organization for promotion and assistance by the civil society, institutions, insurance companies, hospitals, and clinics. The specific practices include: implementation of the labor inspectorate to enforce decrees, establishing standards and promulgating guidelines, creating training courses to promotion ergonomic improvements, providing counseling to help business execution. The result suggests Taiwan that the primary should set up Advisory Committee, and make MSDS Prevention Act, and strengthen cooperation with national insurance agencies, civil associations, groups to implement in the enterprises and workplaces.
