Introduction: Musculoskeletal disorders (MSDs) are common worldwide. Recommendations to reduce discomfort often commence with increasing physical activity levels. In Saudi Arabia, levels of physical activity prior to the COVID-19 pandemic were low. This cross-sectional study aims at estimating the prevalence of MSDs among Saudi physicians, as well as determining the pattern and level of physical activity post lockdown and examining their association. Methods: Physical activity levels were assessed via the International Physical Activity Questionnaire and MSDs were assessed via the Nordic Musculoskeletal Questionnaire. Chi-squared tests with significance levels of <.05 were performed to explore bivariate associations. Unadjusted and adjusted odds ratios (ORs) along with their 95% confidence intervals (CIs) were given by binary logistic regression analyses. Results: A total of 3492 physicians participated in this study, and over half of them (63.55%) reported low physical activity. Risk of MSDs increased with aging and with increasing BMI ( P for trend <.05). Females were more likely to report MSDs (OR = 1.23, 95% CI = 1.07-1.86), as well as physicians with a chronic condition (OR = 1.52, 95% CI = 1.24-1.37) and those who work in shifts (OR = 1.18, 95% CI = 1.03-1.37). Moderate activity conferred a non-significant protective effect (OR = 0.95, 95% CI = 0.79-1.13), whilst high physical activity had a non-significant increased risk of MSDs in this population. Conclusion: Physical activity in this population is astonishingly low, while prevalence of MSDs is relatively high. Significant factors include age, sex, shift work, and the presence of chronic conditions. Current results warrant the consideration of preventive measures for physicians.

Background: Musculoskeletal (MSK) pain is very common in both developed and developing countries with estimate of prevalence ranging from 11-60%. In India, prevalence of Musculoskeletal Disorders (MSDs) was 60% to 100% in selected housewives. Women are also at high risk of developing MSDs as they also do several works at home or working place or at both in which many works include high repetitions, awkward posture, strenuous activity. So, many extrinsic and intrinsic factors combine together and results in MSDs. Movement associated with a structured and planned type of physical activity i.e. exercise, increases an individual’s strength, flexibility, and endurance, which eventually improves postural control, the capacity to resist muscle fatigue, muscle recuperation time, and everyday performance. Physical fitness and exercise have been recommended for lowering WRMSD risk and to improve muscular capabilities and efficiency. Aims and Objectives: The aim of the study was to find out awareness among Indian women regarding the MSDs and role of Physical activity. Method: The study design was a cross-sectional study. A self-administered questionnaire was prepared, it consisted of 12 questions. Questionnaire was disseminated to women through online communication system with attached link. 100 women (age group 20-50years) took part in the survey. The data was analyzed by using Microsoft Excel 2019. Results: From the 100 respondents 41 were housewives and 59 were working women. Awareness among women on MSDs was 68% and about role of Physical activity was 85.75%.80% women were doing regular 20-30minutes physical activity. Conclusion: More than half of women were aware about MSDs where as in good amount women having knowledge about the role of Physical activity. Result showed that awareness among housewives compare to working women is poor to fair and good amount of working women think that physical activity can prevent MSDs and are performing physical activity on daily basis as compare to housewives. Key words: Awareness, Musculoskeletal disorders (MSDs), Physical activity, Women.

The present study investigates the diurnal profiles of locomotive and household activities in older adults with musculoskeletal disorders (MSDs) using an accelerometer. Furthermore, we examined the effect of chronic pain on their diurnal profiles in both activities. Seventy-one older adults with MSDs (73–89 years) were included in this cross-sectional survey, and 25 age-matched older adults (75–86 years) were selected as healthy older adults. The daily physical activities, including steps walked and locomotive and household activity intensities, were recorded using a triaxial accelerometer in terms of metabolic equivalent task-hours per week (MET-h/week). The diurnal profiles of steps and locomotive activities in older adults with MSDs were considerably lower than those of healthy older adults. In contrast, there was no significant decline in household activity. However, the locomotive and household activities were reduced by severe chronic pain. This survey demonstrated that the diurnal profiles of household activity in older people with MSDs as well as those in age-matched healthy older adults were maintained. Furthermore, severe chronic pain influenced both activities. Therefore, the maintenance of household activity throughout the day, as well as the management of chronic pain, may be important strategies for the promotion of physical activity in older people with MSDs.

Purpose Combined with insufficient physical activity (PA) prolonged and improperly performed sedentary work can lead to musculoskeletal disorders (MSDs). The aim of this study was (I) to evaluate the self-reported level of PA and the prevalence of MSDs in male and female teachers, and (II) to investigate the association between PA and MSDs in teachers in Polish primary and secondary schools. Methods The study included 254 teachers from primary and secondary schools from Upper Silesia, Poland, excluding physical education teachers. The level of PA was assessed using the Seven-Day Physical Activity Recall (SDPAR). A standardized Nordic Musculoskeletal Questionnaire (NMQ) was used to assess the prevalence of MSDs. Results A similar percentage of female (80%) and male (90%) teachers met the WHO recommendations on moderate-intensity PA. The recommendations on performing vigorous-intensity PA were met by significantly (p = 0.002) less female than male teachers (50% and 75% respectively). Lower back disorders during the last 12 months and the last 7 days (57% and 45%, respectively) were the most commonly reported MSDs by teachers, followed by neck (53%, 40%), upper back (39%, 28%), and knee disorders (37%, 26%). The highest pain intensity was experienced by the teachers in the lower back and neck. Teachers with a greater number of MSDs were less likely to engage in vigorous-intensity PA and total PA than those with fewer painful areas of the body. Pain intensity in the neck, knees, upper- and lower back, and wrists/hands was negatively related to moderate and total PA. BMI negatively correlated with total PA, moderate-intensity PA vigorous-intensity PA, and high vigorous-intensity PA. Conclusions The study revealed the association between PA and MSDs in studied teachers. The most of the studied teachers met the WHO recommendation, and women were less likely to perform vigorous and high-vigorous PA than men. The lower back and neck disorders were the most common among the teachers.

The aim of this study was to assess the epidemiology of musculoskeletal disorders (MSDs) among the teaching staff of the University of Douala and determine their association with physical activity (PA) practice. The Nordic questionnaire was used to assess MSDs. Ricci–Gagnon questionnaire was used to determine the level of PA. We recruited 104 participants mean-aged 42 ± 8 years, 80% male. Previous 7 days and 12 months prevalence were 56.7% and 80.8%, respectively. The most affected body regions were neck, shoulders and lower back. No significant association was found between MSDs and PA. Celibacy was significantly associated with previous 7-days MSDs (p = 0.048) while age ≥ 45 years and job seniority ≥ 10 years were significantly associated with a reduced risk of previous 12-months MSDs (p = 0.039 and p = 0.016, respectively). The prevalence of MSDs among university of Douala teaching staff showed no significant effect with the practice of PA.

Nowadays, the ergonomic issues become more and more important in all economic activity domains. Work-related Musculoskeletal Disorders (MSDs) represent the main problem generated by the poor ergonomic design of the workplaces. The healthcare domain involves high level ergonomic risks related to physical and mental load of the work which could lead to MSDs. The paper presents an analysis of these ergonomic risks for physiotherapy activity and identifies potential measures to improve the health and safety in this domain. The physical load of the physiotherapist’s work is generated by the risk factors such as awkward postures, repetitive movement or working with patients with motor disabilities. The mental load of the physiotherapist’s work depends on risk factors such as working with patients with cognitive impairment and daily or weekly patient flows. The proposed preventive measures are organisational and technical. The organisational measures are based on the requirements of the occupational health and safety (OHS) legislation and on the good practice examples. The technical measures are based on the analysing the documentation of physiotherapy modern equipment. The results of the study can be used to improve the ergonomics and the health and safety of any workplace in physiotherapy activity.

Abstract Background Welders demonstrate a high prevalence of musculoskeletal disorders (MSDs), as indicated by high rates of illness-related absenteeism. Leisure time physical activity (LTPA) could be a preventive strategy. However, little is known about LTPA prevalence and its association with MSDs among welders. Aims The aim of this study was to analyse the prevalence of MSD and LTPA levels among welders and to identify risk factors for the main disorder of low back pain (LBP). Methods The following data were collected from 145 welders from 34 companies in the German steel industry: individual factors (demographics, health behaviour), job-related factors (welding process, welding hours per day, employment years, shift work, ergonomic tools) and MSD (Nordic questionnaire). LTPA (International Physical Activity Questionnaire) was calculated to determine the metabolic equivalent of task (MET) per week as an objective measure of energy expenditure. Prevalence and multivariate regression analysis were calculated to determine odds ratios (ORs). Results The 12-month prevalence of LBP was 71%, for neck pain 61% and for shoulder pain 55%. Forty-two per cent of the participants accumulated <600 MET/week. The multivariate regression model revealed LTPA <600 MET/week (OR 3.4, 95% CI 1.05–10.85) and neck pain in the previous 12 months (OR 5.2, 95% CI 2.02–13.56) to be significantly associated with LBP. Conclusions The results show a high prevalence of MSDs and thus a strong requirement for intervention. Therefore, LTPA should be prioritized and employers should encourage access to regular activity.

This study aimed to investigate the prevalence of upper limb musculoskeletal disorders (MSDs) and their association with smartphone addiction and smartphone usage among university students in the Kingdom of Saudi Arabia during the COVID-19 pandemic. A total of 313 university students aged 18 years and older who owned a smartphone and used it during the preceding 12 months participated in this cross-sectional study. The prevalence of upper limb MSDs, smartphone addiction/overuse, and levels of physical activity were recorded using the standardized Nordic musculoskeletal questionnaire, the smartphone addiction scale (short version), and the international physical activity questionnaire (short form), respectively. Data collection was performed on campus between March and May 2021. Binary logistic regression was used to determine the association between the prevalence of upper limb MSDs and smartphone addiction/overuse and levels of physical activity. The 12-month prevalence of MSDs of the shoulder, elbow, and wrist/hand regions due to smartphone use among participants was found to be 20.13%, 5.11%, and 13.42%, respectively. Shoulder (odds ratio (OR) = 11.39, 95% confidence interval (CI) = 4.64–27.94, p < 0.001), elbow (OR = 15.38, 95% CI = 1.92–123.26, p = 0.01), and wrist/hand MSDs (OR = 7.65, 95% CI = 2.75–21.22, p < 0.001) were more prevalent among participants who were categorized as having smartphone addiction/overuse measures. Promoting awareness about the healthy use of smartphones, including postural education and decreasing screen time, is necessary to reduce smartphone-related MSDs.

PurposeTo the best of our knowledge, the studies on determining adherence to the Mediterranean dietary pattern (MDP) in Iran as a non-Mediterranean country are scarce. Thus, the aim of the study is to determine the adherence to the MDP in a sample of female adolescents who are residents of Tehran, Iran.Design/methodology/approachIn this cross-sectional study, 263 female adolescents aged 15-18 years were studied. Information on socio-demographic, lifestyle and anthropometric variables were obtained using a structured questionnaire. Also, dietary intakes were determined using a validated 168-item food frequency questionnaire. Adherence to MDP was characterized using Mediterranean-style dietary pattern score (MSDPS).FindingsTypically, the mean ± SD MSDPS was low in the present study (15.9 ± 5.6). The mean ± SD age and body mass index of the study population was 16.2 ± 0.9 years and 22.2 ± 4.1 kg/m2, respectively. In this study, the maximum MSDPS was 34.3, which was only one-third of maximum possible score (100). Multiple linear regression analyses showed that higher MSDPS scores were positively associated with age (standardizedβ= 0.1;p= 0.006), higher energy intake (standardizedβ= 0.2;p< 0.001) and marginally higher physical activity (standardizedβ= 0.1;p= 0.079).Originality/valueUnderstanding low adherence to MDP in Tehranian female adolescents can provide basic knowledge to launch systematic programmes for gravitation toward MDP.

Introduction: Musculoskeletal disorders (MSDs) are a collection of symptoms in the human skeletal and muscular systems, which are characterized by discomfort or pain. The International Labor Organization (ILO) stated that MSDs are the most common health problem among office workers in 27 countries under the European Union. Therefore, this study aims to determine the risk factors for MSDs among office workers. Method: This study used the literature review method by accessing an online database using different keywords, namely risk factors, musculoskeletal disorders, and office workers. Subsequently, 939, 1,421, and 243 articles were obtained from Google Scholar, ProQuest, and PubMed.Gov, respectively, with a total of 2,603. The inclusion criteria include papers published between 2011 and 2021, relevant titles and abstracts, primary study with a cross-sectional design, as well as full-text availability. Incomplete articles that are irrelevant to the topic were then excluded, after which a total of eight were selected for analysis. Result: Based on selected articles known that the risk factors for MSDs include age, gender, knowledge of ergonomics, work posture, work facilities, duration of work, physical activity, and psychosocial factors in the workplace. Conclusion: The significant risk factors for MSDs include increasing age, female gender, increased work duration, poor knowledge of ergonomics, wrong work posture, non-ergonomic support facilities, lack of physical activity, as well as poor psychosocial conditions in the workplace.

Several studies have identified improvements in the risks of cardiovascular disease in adults following a Mediterranean dietary pattern. However, data are scarce on its association with coronary artery calcification (CAC) and pericardial adiposity (PAT) in US adults with and without diabetes. To address this gap, we conducted a case-control study using baseline data from the Coronary Artery Calcification in Type 1 Diabetes (CACTI) study [n = 1255; Type 1 Diabetes (T1D): n = 563; non-Diabetes Mellitus (non-DM): n = 692]. Participants completed a validated food frequency questionnaire, fasting (12 h overnight fast) biochemical analyses, and a physical examination including anthropometric measures. CAC and PAT were measured using electron beam-computed tomography. Logistic regression models were used to examine the associations of the Mediterranean-Style Dietary Pattern Score (MSDPS) with CAC (presence or absence), and linear regression models were applied to PAT analyses. In all of the adjusted models, no significant associations with CAC were found. For PAT, an increasing MSDPS was consistently associated with its lower volume in models adjusted for age, sex, diabetes status, total calories, and body mass index (all p < 0.05). The association between MSDPS and PAT was attenuated after adjusting for serum lipids and physical activity. In conclusion, the baseline data from the CACTI study show that a greater adherence to MSDPS is associated with a lower PAT volume and provide evidence that the Mediterranean dietary pattern is associated with lower cardiovascular risk markers.

Background: Workers who undertake occupations that require bending, climbing, crawling, reaching, twisting, excessive activity, or repeated movements may suffer from musculoskeletal disorders (MSDs). MSDs can be prevented by doing Workplace Stretching Exercise (WSE) which is useful for minimizing the risk of musculoskeletal injury, fatigue reduction, muscle balance, and posture improvement, and muscle coordination improvement. Purpose: To analyze the difference before and after giving WSE to the reduction of MSDs complaints. Method: This research takes a quantitative approach, utilizing a quasi-experimental design in one group before and after WSE administration. Total sampling is used for sampling. The respondents of this study were 34 workers in the production division of PT Crown Pratama in 2021. The T-paired test was utilized as a statistical test in this study. Result: The results of the univariate test mean MSDs complaints before and after WSE administration were 42.97 and 36.29. Conclusion: The bivariate test revealed differences in complaints of Musculoskeletal Disorders (MSDs) before and after workplace stretching exercise.

According to the European Agency for Health and Safety at Work, changes in employment arrangements, new technologies and an increasing ageing population are key sources of emerging risks. New and emerging risks should be a major area of interest for every organisation, as a thorough risk prevention activity is key to high organisation efficiency and increased employee wellbeing. Musculoskeletal disorders (MSDs) are not a new risk category by themselves, but the changing characteristics of the work system generate new types of MSDs as a profession-related pathology (work-related MSDs). There is limited literature on this matter, hence the paper provides relevant insights and a new perspective on ergonomic risks and MSDs. Also, the paper presents a comparative analysis of ergonomic risks in the EU and Romania – based on secondary data – and identifies emerging risks in this category.

With the aim of providing genetic materials for breeding drought-resistant wheat varieties, the physiological and metabolic plasticity of three drought-resistant wheat multiple synthetic derivative lines (MSDLs) and their backcross parent “Norin 61” (N61) were evaluated in response to drought stress. The results indicated that the D-genome introgressions from Aegilops tauschii into the MDSLs improved their drought-adaptive traits. Specifically, MNH5 and MSD345 showed higher photosynthesis rates and triose phosphate utilization than N61 under control conditions, resulting in greater accumulation of glucose and sucrose in the shoots. However, under drought stress, MNH5 and MSD345 had higher intrinsic water use efficiency than MSD53 and N61. The total antioxidant capacity and superoxide dismutase activity increased in all three MSDLs, whereas no significant changes were found in N61 in response to drought stress. Metabolome analysis identified six common drought-induced metabolites in all of the investigated genotypes. However, four metabolites (adenine, gamma aminobutyric acid, histidine, and putrescine) each specifically accumulated in an MSDL in response to drought stress, suggesting that these metabolites are important for MSDL drought resistance. In conclusion, MNH5 and MSD345 showed better adaptive responses to drought stress than MSD53 and N61, suggesting that these two MSDLs could be explored for breeding drought-resistant wheat lines.

ABSTRACTIntroduction: Musculoskeletal Disorders (MSDs) is one of the health problems caused by the used equipment or performed activity while working. The workers in the packaging section of the iron and steel industry who do the packaging process manually are exposed to the risk of experiencing MSDs due to the working attitudes and non-ergonomic postures. This study aims to identify the correlation between ages, years of service, as well as working postures and the complaints of MSDs experienced by the workers of the packaging section of iron and steel industry in Sidoarjo. Methods: This study applied a cross-sectional design. The research population was all workers in the packaging section of an iron and steel industry in Sidoarjo, reaching 27 people. The research samples are the total population of the workers in the packaging section of an iron and steel industry in Sidoarjo. The risk assessment of MSDs was carried out by using the Rapid Entire Body Assessment (REBA) method, while the risk complaints were measured by using the Nordic Body Map (NBM) questionnaire. The data were tested by using Chi-Square. Results: The results revealed that there were moderate correlations between the age and the MSDs complaints (phi coefficient=0.335), between the years of service and the MSDs complaints (phi coefficient=0.433), and between the working postures and MSDs complaints (phi coefficient=0.401). Conclusion: The moderate-level of correlation still affected the occurrence of MSDs complaints. Keywords: ages, years of service, working postures, musculoskeletal disorders complaints

Healthcare professionals perform daily activities that can lead to musculoskeletal disorders (MSDs). The objective of this review was to summarize these MSDs by body areas in relation to healthcare professions. The underlying question is, worldwide, whether there are areas that are more exposed depending on the occupation or whether there are common areas that are highly exposed to MSDs. This issue has been extended to risk factors and responses to reduce MSDs. The review was conducted according to the PRISMA guidelines between February and May 2022. Google scholar and Science Direct databases were scanned to identify relevant studies. Two authors independently reviewed, critically appraised, and extracted data from these studies. Overall and body area prevalence, risk factors, and responses to MSDs were synthetized by occupational activity. Among the 21,766 records identified, 36 covering six healthcare professions were included. The lower back, neck, shoulder and hand/wrist were the most exposed areas for all healthcare professionals. Surgeons and dentists presented the highest prevalence of lower back (>60%), shoulder and upper extremity (35–55%) MSDs. The highest prevalence of MSDs in the lower limbs was found for nurses (>25%). The main causes reported for all healthcare professionals were maintenance and repetition of awkward postures, and the main responses were to modify these postures. Trends by continent seem to emerge regarding the prevalence of MSDs by healthcare profession. Africa and Europe showed prevalence three times higher than Asia and America for lower back MSDs among physiotherapists. African and Asian nurses presented rates three times higher for elbow MSDs than Oceanians. It becomes necessary to objectively evaluate postures and their level of risk using ergonomic tools, as well as to adapt the work environment to reduce exposure to MSDs with regard to the specificities of each profession.

PT PJC is a company synthetic resin. Synthetic resin is that produced by PT PJC is sold to the market in three types of packing, one of then is the drum packing type that weigh 208 kg. One of the activities that use the manual handling product (manual material handling) is the activity of filling, the drum-packed product will be transfered with drum packaging to the finishing goods area which done by the man force. Manual material handling concept has several advantages, one of which is easy to do by humans. However, manual handling material handling becomes an issue if the material load exceeds the maximum lifting of the worker because of the potential risk of injury to the human body, especially if it is carried out simultaneously for a relatively long period of time. One of the risks of human injury that can be experienced is Musculoskeletal Disorders (MSDs). This research will investigate the musculoskeletal complaints on Filling workers which will form the basic of the ergonomically-based Standard Operating Procedure (SOP) design basic. Data is taken by a Nordic Body Map (NBM) questionnaire. The result shows that most of the dominant body pain felt by the worker as the impact of previous day’s work was the complaints of pain on the left and right wrists, left and right palms, left and right knees, left and right calves, left and right ankles, while the pains felt by the workers after the activity are pain in the back, waist, left and right elbow, left and right thighs, left and right calvs, left and right ankles. The pain work will disappear after the night rest, but there is no guarantee that the worker’s body will be fit in the morning, because of the remnants of body pain that have not been fully fit, thus affecting the readiness of physical conditions at work in the morning. These body pain can be reduced by designing the right standard operating procedure (SOP) based on an ergonomic work attitude. Musculoskeletal pain before the activity were 39.3 ± 10.6 and after activity was 76.5 ± 14.9 or an increase in musculoskeletal pain of 94.66%.

BackgroundOccupational light vehicle driving is becoming increasingly important in the parcel delivery/messaging sector faced with new consumer practices. Our objective was to analyze the effect of driving of light vehicle for the mail/parcel delivery on low back pain (LBP) and upper-extremity musculoskeletal disorders (UEMSDs) taking into account work organization. We also aimed to identify the protective factors from MSDs that could be implemented into this specific workplace.MethodsThe study was carried out in 406 postal workers (306 with driving delivery activity, 100 with foot delivery/manual handling activities). Subjects completed a self-administrated questionnaire about personal characteristics and working conditions assessing occupational driving, physical constraints, psychosocial factors and work organization. Work organization was also assessed at the establishment level. MSDs were assessed by the Nordic Questionnaire, with some additional questions for LBP. For UEMSDs, a medical examination using a standardized clinical methodology of the European consensus was carried out. Statistical analysis was performed separately in men and women by multivariable logistic regression modeling for the UEMSDs and by item response theory approach for LBP.ResultsDriving time and high perceived driving-related physical constraints are associated to LBP in men. Carrying loads>3 Kg, awkward postures and high perceived physical demands related to parcel loading and delivery are associated with MSDs for both sexes. The main psychosocial risk factors are the lack of reward, being mobbed and the necessity of undertaking tasks that the worker disapproves. Protective factors are the use of vehicles fitted with automatic gearbox and taking breaks from work; at establishment level, drive training and use of supplementary staff during peak periods.ConclusionThe effect of driving of light vehicle on MSDs seems quite limited whereas physical and psychosocial constraints are clearly risk factors. Targeting work organization could protect postal workers with driving delivery activity from MSDs.

There are 22 million veterans in the U.S. Armed Forces. Past research on the musculoskeletal health of military veterans has explored the prevalence of musculoskeletal disorders (MSDs) but largely avoids situating findings within a theoretical framework. This article uses Pierre Bourdieu’s theory of cultural capital to contextualize veteran’s greater rates of MSDs compared to nonmilitary civilians. Cultural capital consists of objectified, institutional, and embodied capital that can be transubstantiated to capital in other areas. Embodied or physical capital is central to military service, and military veteran status is beneficial in accessing social and institutional capital. Using the 2012–2014 National Health Interview Survey, we show veterans are more likely to report activity-limiting MSDs, and at younger ages, compared to nonveterans. Physical capital is central to, and impaired by, status as a veteran.

Background: Occupational hazards are common in different working populations. Musculoskeletal disorders (MSDs) are the most important occupational hazards particularly in dental professionals. This disorder which is multi factorial in origin has relation with different characteristics. The study aims to find out the association between personal characteristics in terms of socio demographic, occupation characteristics and MSDs among the dental surgeons working in Dhaka city.
Methods: Present cross sectional study was conducted among purposively selected 290 dental surgeons working in thirteen private and public tertiary level hospitals in Dhaka city. A structured questionnaire was used for data collection including socio demographic and occupational characteristics which reflect the personal characteristics of dental surgeons. To determine the MSDs, Nordic Musculoskeletal Questionnaire (NMQ) was used which records the prevalence of MSDs in terms of musculoskeletal symptoms. Collected data were analyzed by using SPSS software (Version 22).
Results : Almost 64.0% dental surgeons experienced MSDs in past 12 months in at least one region of the body, and the major affected part was neck, followed by lower back, shoulders and hands / wrists. Regarding the relationship between personal characteristics and MSDs, present study found significant relationship exists between some socio demographic characteristics like age, physical activity; some occupational characteristics like work status, practicing area, practicing four handed dentistry, maintaining back position upright, psychosocial stress with MSDs in chi square test.
Conclusion: This study concludes that the existence of significant relationship between different personal characteristics and MSDs among dental surgeons which need to be address properly, so that dental professionals will be able to take corrective measures to combat with this disorder.

The kind of research was a quantitative study with a cross-sectional approach. The Population of this research is 36 people. The taking of the sample was done by a total sampling method that is 36 people. The test used was the Chi-square test. The results of the research showed that 21 people (58,3%) suffer from musculoskeletal disorders and 19 people (52,8%) suffer from work fatigue. The results showed that as many as 29 people (80.6%) experienced MSDs complaints and as many as 25 people (69.4%) experienced work fatigue. The analysis showed that there was no relationship between age and smoking habits with MSDs complaints, while the risk level of MMH and ambient temperature had a relationship with MSDs complaints. There is no relationship between age, smoking habits, the level of risk of MMH with work fatigue, while ambient temperature has a significant relationship with work fatigue. Therefore, it is advisable for workers to stretch their muscles during breaks so as to reduce MSDs complaints. Meanwhile, the workers cooperative union needs to provide drinking water facilities in order to reduce worker dehydration.

Manual material handling if done inappropriately can pose a risk of injury to the body, mainly in the spine, which is usually referred as musculoskeletal disorders (MSDs). Based on direct interview with warehouse workers of PT. X, it is known that in the lifting or transfering mineral water activity often causes pain in the waist and spine. This study is intended to analyze the work posture and the load level that is safe for workers to reduce the risk of MSDs, the analysis is carried out with the Recommended Weight Limit (RWL) method. From the calculation gained RWL origin = 15.36kg / 34.07lbs and destination RWL = 18.54kg / 41.12lbs. Then the origin LI value = 0.9 and destination LI = 0.8. From the results of the Lifting Index can be concluded that the risk level of this work is low and there is no problem with the lifting work. The weight of load raised does not exceed the recommended lifting limit, so there are no repairs to the work needed, but the activity must keep to get attention so the LI value can be maintained and the activity does not bear the risk of spinal injury.

Musculoskeletal problems are problematic in Indonesia because manual work activities such as lifting, transporting, pulling and pushing are still being done. Pottery-making workers in the Kasongan are still doing those moves traditionally such as lifting, transporting, pulling and pushing manually. The purpose of this study was to analyze the risk of MSDs in the pottery making workers in Kasongan. This research was cross sectional design. The sample amounted to 78 workers selected using accidental sampling techniques. The instruments used Nordic Body Map questionnaire and Rapid Entire Body Assessment. Data analysis was using the chi fisher test. The results showed that the variables associated were age (sig= 0.000) and variables that had no relationship were gender (sig= 0.341) and work posture (sig= 0.352). The risk factor associated with complaints of MSDs is age, so to reduce the risk of the occurrence of MSDs, they can do physical activity or stretch muscles.

ABSTRACT Silencing of gene transcription involves local chromatin modification achieved through the local recruitment of large multiprotein complexes containing histone deacetylase (HDAC) activity. The mammalian corepressors mSin3A and mSin3B have been shown to play a key role in this process by tethering HDACs 1 and 2 to promoter-bound transcription factors. Similar mechanisms appear to be operative in yeast, in which epistasis experiments have established that the mSin3 and HDAC orthologs (SIN3 and RPD3), along with a novel protein, SDS3, function in the same repressor pathway. Here, we report the identification of a component of the mSin3-HDAC complex that bears homology to yeast SDS3, physically associates with mSin3 proteins in vivo, represses transcription in a manner that is partially dependent on HDAC activity, and enables HDAC1 catalytic activity in vivo. That key physical and functional properties are also shared by yeast SDS3 underscores the central role of the Sin3-HDAC-Sds3 complex in eukaryotic cell biology, and the discovery of mSds3 in mammalian cells provides a new avenue for modulating the activity of this complex in human disease.

Manual material handling (MMH) activities utilize human’s effort with minimal aid from mechanical devices. MMH is typically associated with poor lower back posture which can lead to lower back injury. The likelihood to develop musculoskeletal disorders (MSDs) increases when poor working posture exist in combination with repetition and/or forceful exertion. In manual transfer activity, the distance between lifting origin and destination could affect workers’ exposure on poor lower back working posture. An experimental study was conducted to investigate the effect of transfer distance to lower back twisting and bending pattern in manual transfer activity. Positional body joints data of 26 male subjects were captured using the combination of motion capture (MOCAP) system with MVN studio software. Calculated data were plotted against time to track subjects’ lower back twisting and bending behavior. In general, longer the transfer distance would result in smaller twisting angle but higher bending angle. Statistical analysis in this study suggests 0.75m to 1.00m as the optimum transfer distance to balance lower back twisting and bending exposure on workers. This study is envisioned to provide insights for practitioners to consider space requirements for MMH activity to minimize lower back twisting and bending, and consequently the development of MSDs.

Background: Ikat weavers work manually and non-stop for a long duration of time, which increases the risk of occupational diseases such as musculoskeletal disorders (MSDs). Ikat weaving craftsmen perform work manually and non-stop for a long duration of time which generates occupational diseases such as musculoskeletal disorders (MSDs). This study aimed to determine the analysis of complaints of musculoskeletal disorders (MSDs) among ikat weavers in Langa Bajawa. Subjects and Method: A cross-sectional study were conducted from August to September 2022 among ikat weaving craftsmen in Langa Bajawa region, Ngada, East Nusa Tenggara. A total of 38 subjects were included in this study. The dependent variable was complaints of musculoskeletal disorders (MSDs). The independent variables were age, working period, duration of work, body posture, workload, repetitive activity, stretching, and back rest. The data were collected with study questionnaires, Nordic Body Map questionnaires, Rapid Upper Limb Assessment (RULA) ques-tionnaires, and obser¬vations. The data were analyzed using Chi-square. Results: Age >35 years (OR= 1.07; 95% CI= 1.07 to 17.79; p= 0.034), working period >10 years (OR= 3.85; 95% CI= 0.98 to 15.12; p= 0.049), posture with RULA score >4 (OR= 5.66; 95% CI= 1.36 to 23.46; p= 0.013), working hours >8 hours/day (OR= 10.5; 95% CI= 2.16 to 51.42; p= 0.002), repetitive activity (OR= 11.55; 95% CI= 2.41 to 55.39; p= 0.001), rarely stretching (OR= 0.04; 95% CI= 0.00 to 0.27; p< 0.001), and not having a backrest (OR= 0.09; 95% CI= 0.02 to 0.44; p= 0.001) had a significant effect on complaints of musculoskeletal disorder in ikat weaving craftsmen. Meanwhile, the workload of a person who has a pulse of (> 125 BPM) affected the complaints of MSDs, however, it was statistically insignificant. Conclusion: Age >35 years, working period >10 years, posture with a RULA score of >4, working hours >8 hours/ day, repetitive activities, rarely stretching, not having a backrest, and the work¬load of a person with a pulse rate (> 125 BPM) affect complaints of musculoskeletal disorder in ikat weaving craftsmen. Keywords: complaints of musculoskeletal disorders, craftsmen, ikat weaving.

Musculoskeletal disorders (MSDs) are one of the leading causes of occupational injuries and disabilities. The purpose of this study was to assess the prevalence of MSDs and occupational factors affecting MSDs among ethnic lychee–longan harvesting workers in northern Thailand. A cross-sectional study was conducted in the areas of three upper northern provinces of Thailand. The study areas are located in the highlands and rural plains, where many ethnic minority groups live, including Indigenous, Mien, Karen, and Lua. The majority of them work in a farm of perennial fruit trees, mainly lychee and longan. During the harvest season, 404 participants were recruited for the study using the convenience sampling technique. Data were collected using questionnaires that included general information, an ergonomic risk assessment, and a standardized Nordic questionnaire for assessing MSDs in 10 body parts. The average age of lychee–longan harvesting workers was 48.8 years. Almost all (99.5%) reported MSDs in one or more body regions in the previous seven days of work. The prevalence of MSDs was highest in the hands (82.9%), followed by the shoulders (82.2%) and the neck (79.7%). The total ergonomic risk scores, which included awkward posture, heavy carrying and lifting, repetitive activity, land slope, and equipment, were found to be significantly associated with MSDs in part of the neck (AOR = 1.17, 95%CI = 1.11–1.23), shoulder (AOR = 1.15, 95%CI = 1.10–1.21), elbow (AOR = 1.18, 95%CI = 1.12–1.24), hand (AOR = 1.12, 95%CI = 1.07–1.18), finger (AOR = 1.33, 95%CI = 1.24–1.44), upper back (AOR = 1.14, 95%CI = 1.09–1.20), lower back (AOR = 1.16, 95%CI = 1.11–1.22), hip (AOR = 1.11, 95%CI = 1.06–1.15), knee (AOR = 1.18, 95%CI = 1.12–1.24), and feet (AOR = 1.21, 95%CI = 1.15–1.28) when adjusting for ethnicity, sex, age, BMI, and work experience. Many parts of ethnic workers’ bodies have been affected by occupational injuries, with a high risk of upper extremity injury. As a result, using an ergonomic approach to improving the working environment and appropriate posture movement is very beneficial in preventing MSDs among ethnic harvesting workers.

Tailor is one of the professions that has MSDs risk. It is because of the working posture, such as sitting for a long time and repetitive movements. The purpose of this study is to determine correlation between working postures and Musculoskeletal Disordes (MSDs) of Tailors in Ulak Kerbau Baru Village Ogan Ilir. This research was an cross-sectional and method of sampling in this study was using accident sampling with sample were 75 respondents. Rapid Entire Body Assessment (REBA) method was used assessed the risk of working posture and questionnaires. Nordic Body Map was used determine of Musculoskeletal Disorders. The data is performed using univariate and bivariate with chi-square. Based on calculations used the REBA posture tailor working 42.7% of respondents has high risk and 57.3% has medium risk. Results of this analysis used statistical there were a significant relationship between age (pvalue = 0.006 CI 1,730-25,281), working period (pvalue = 0.023 CI 1,343-30,271), working posture (pvalue 0.027 CI 1,284-11,847), and the working time (pvalue = 0.032 CI 1,145-74,602) with Musculoskeletal Disorders (MSDs), and there was no significant relationhips between the sexes (pvalue = 0.610 CI 0,224-1,898) with Musculoskeletal Disorders (MSDs). The majority of tailor work posture were at high risk, the researcher suggests to do intervention on modified factors, which are working postures and working time. Intervention can be done by using ergonomic work chair and make time to do stretch up (physical activity) every 30 minutes to reduce muscle fatigue.

Manual patient handling is a major cause of musculoskeletal disorders (MSDs) among caregivers. Pulling patients up in bed (PUIB) is one of the most frequently performed patient handling activities, for which repositioning aids are usually recommended. However, it is not clear how to choose repositioning aids for a patient of a given weight, such that the risk of MSDs can be reduced. The current study investigates the physical stresses on caregivers across three patient weight levels, and for common types of repositioning aids during the PUIB activity. Ten caregivers were recruited to preform PUIB tasks while motion capture, ground reaction force, and hand reaction force were measured. Spinal compressive load (L5/S1) was estimated using AnyBody Modeling System software. Repositioning aids and patient weight significantly affected the physical stresses on caregivers. Peak L5/S1 compressive load, peak pulling force, and perceived exertion were lowest for the air-assisted repositioning devices, second lowest for the friction reducing sheet, second highest for the turn and position systems, and highest for the draw sheet. Except for the air-assisted repositioning device, other tested repositioning aids are not adequate to mitigate the risk of MSDs. A mechanical lift should be considered as a robust alternative to repositioning aids that can safely accommodate all patient regardless of weight.

Pine resin is one of the non-timber forest products commodity that has excellent prospects. Pine resin harvesting is generally divided into two main activities: tapping and collecting works. Collecting activity that is commonly done under manual technique is classified as manual material handling that can trigger musculoskeletal disorders (MSDs). This work posture study offers an overview of MSDs disruption level faced by workers. Therefore, the proper corrective action can be taken. Motion sequences in selected work cycles were captured by using the Kinovea software. Work posture analysis was performed by a combination of the natural range of motion (SAG), Rapid Upper-Limb Assessment (RULA), and Rapid Entire Body Assessment (REBA). SAG analysis shows that the body’s parts having a high probability of being injured are the back and shoulders. Work posture analysis using RULA and REBA verified that bending or half bending may cause MSDs. The ergonomics risk in these positions might be higher due to the influence of load and repetitive factors. Reducing the posture of bending/half bending, reducing the weight of the resin bucket, and taking a short break/rest in between work activities should be considered as potential strategies in reducing the ergonomics risks that may occur during the resin collection work. Keywords: forestry workers, musculoskeletal disorders, non-timber forest products, oleoresin, natural range of motion

Background: Occupational hazards believed to cause musculoskeletal disorders in rope workers are traditionally associated with maintaining incongruous postures for prolonged periods of time. Design and methods: A cross-sectional survey was conducted on 132 technical operators in the wind energy and acrobatic construction sectors, who work on ropes, analysing the ergonomic characteristics of the environments, the way in which tasks are carried out, the strain perceived by individual workers, and assessing the presence of any musculoskeletal disorders (MSDs) by means of an objective examination focused on the anatomical districts that were the object of our study. Results: Analysis of the data obtained showed that there were differences in the perception of the level of physical intensity and perceived exertion between the groups of workers. Statistical analysis also revealed a significant association between the frequency of MSDs analysed and perceived exertion. Discussion: The most significant finding to emerge from this study is the high prevalence of MSDs of the cervical spine (52.94%), the upper limbs (29.41%), and the dorso-lumbar spine (17.65%). These values differ from those classically found in those exposed to the risk of conventional manual handling of loads. Conclusions: The high prevalence of disorders of the cervical spine, the scapulo-humeral girdle and the upper limbs, indicates the need to consider the forced position to be assumed for a large part of the work activity, staticity, and the inability to move the lower limbs for long periods as the predominant risk in rope work.

Sheppard, David N., and Michael J. Welsh. Structure and Function of the CFTR Chloride Channel. Physiol. Rev. 79 , Suppl.: S23–S45, 1999. — The cystic fibrosis transmembrane conductance regulator (CFTR) is a unique member of the ABC transporter family that forms a novel Cl− channel. It is located predominantly in the apical membrane of epithelia where it mediates transepithelial salt and liquid movement. Dysfunction of CFTR causes the genetic disease cystic fibrosis. The CFTR is composed of five domains: two membrane-spanning domains (MSDs), two nucleotide-binding domains (NBDs), and a regulatory (R) domain. Here we review the structure and function of this unique channel, with a focus on how the various domains contribute to channel function. The MSDs form the channel pore, phosphorylation of the R domain determines channel activity, and ATP hydrolysis by the NBDs controls channel gating. Current knowledge of CFTR structure and function may help us understand better its mechanism of action, its role in electrolyte transport, its dysfunction in cystic fibrosis, and its relationship to other ABC transporters.

This study aims to identify the operator's posture at work, determine the factors that influence the occurrence of musculoskeletal disorders (MSDs) complaints, and give suggestions for improving the postures. The method used in the research is Nordic Body Map (NBM) and Rapid Entire Body Assessment (REBA). Material handling processes carried out by some operator's production in the line press magazine stamping could be affected body postures. If the company does not carry out an analysis of the situation, it could be impacting the risk of Musculoskeletal Disorders for the operator who is working in this area. Process manual handling was carried out 4800 cycles in a day (8 hours of work) with a bent posture, causing complaints of musculoskeletal disorders (MSDs). The results of Nordic Body Map (NBM) questionnaire processing results scored 75 and 81 points, and the second activity was the REBA assessment when the operator took material from the train. The REBA score was 8. The results of this study have high scores for NBMs and REBAs, requiring investigation and changing work attitudes.

Weeding activity in vegetable cultivation carried out by women is one of the drudgery prone activities. Women are regularly adopting poor and static posture while doing weeding for long hours by traditional equipment, resulting in various physical load on spine or lumbo-sacral region leads to drudgery coupled with work related musculoskeletal disorders (MSDs). The research paper aims to assess and quantify the drudgery with weeding activity by rural women in which physiological ergonomics evaluation was done for traditional method and with improved technological support with three replications of fifteen minutes work cycle without rest pause. Ergonomic parameters namely Heart Rate, Energy Expenditure Rate, Total Cardiac Cost of Work, Physiological Cost of Work, VO2 Max were measured during the experiments. Observations were recorded on farm women worker with normal health, without any major illness, regularly involved in farm operations and were in the age group of 25 to 45 years. Weeding activity of farm women was quantified and a sample of 10 physically fit rural women having permissible limit of physiological parameters were selected for the study. It was found from investigation that there was reduction in human physiological parameters, viz. heart rate, energy expenditure rate, Total Cardiac Cost of Work, Physiological Cost of work, Blood pressure and Oxygen Saturation.

Uncomfortable posture may not contribute only to the development of musculoskeletal disorders (MSDs) but also to the loss of energy and the decrease in work efficiency (WE). Measuring WE based on activity energy expenditure (AEE) have not got much attention in work places. The study aims to develop a model of work efficiency (WE) based on body posture for performing horizontal drilling tasks. Ten subjects, all men with an average age of 23.3 ± 0. 67, participated in the experiment. Six coordinated postures of shoulder and trunk flexion were tested. Activity Energy Expenditure (AEE) and Work Efficiency (WE) were the dependent variables. Repeated measures ANOVA were used to analyze the data. The findings showed that statistically significant trends (P <0.01) of increasing AEE while the trunk and shoulder move away from the neutral posture. Overall, these results provide valuable insights into assessing WE on the basis of the AEE and the activity wasted energy (AWE) due to unproductive movements while standing in difficult postures, taking the neutral posture as a zero reference of wasted energy.

Whole-body vibration (WBV) is known to be a leading factor for developing musculoskeletal disorders (MSDs). As mining vehicle operators are exposed to frequent transient shocks and substantial non-vertical WBV exposures, they may be at a greater risk than on-road vehicle operators. However, the impact of such exposures is not well understood. Therefore, this study aimed to evaluate how the exposure to WBV affected physiological stress and whether mining vehicles’ vibration with substantial non-vertical WBV components would further increase the level of physiological stress as compared to on-road vehicle vibration (vertical-axis dominant vibration). In a repeated-measures laboratory study, a 6-degree-of-freedom motion platform was used to recreate three different types of field-collected vibration profiles: vertical-axis dominant vibration measured from on-road long-haul trucks (VA), multi-axial vibration measured from mining vehicles (MA), and no vibration (control condition: CC). Subjects were exposed to each vibration condition for 2-hour sessions over three different experimental days. Blood samples were collected before and after each exposure session in order to measure biological markers for inflammation (tumor necrosis factor-α: TNFα), muscle damage (creatine kinase), and physiological stress (cortisol). During the 2-hour WBV exposures, muscle activity in the neck and low back muscles was measured using electromyography. The results showed that there were statistically significant differences in TNFα (inflammatory response) levels between vibration exposure (VA and MA) and the control condition (no vibration) (p = 0.01); however, these differences are not considered as clinically significant changes. No significant changes were found in muscle damage (creatine kinase) and physiological stress (cortisol). The vibration exposure conditions (VA and MA) showed higher low back muscle activity; however, these differences did not reach statistical significance (p’s > 0.08). Neck muscle activity did not differ among exposure conditions. The lack of effect in these results may support previous findings that MSDs develop from prolonged exposure to WBV and not from acute exposure to physical risk factors.

ABSTRACT Clostridium perfringens commonly occurs in food and feed, can produce an enterotoxin frequently implicated in food-borne disease, and has a substantial negative impact on the poultry industry. As a step towards new approaches for control of this organism, we investigated the cell wall lysis system of C. perfringens bacteriophage φ3626, whose dual lysis gene cassette consists of a holin gene and an endolysin gene. Hol3626 has two membrane-spanning domains (MSDs) and is a group II holin. A positively charged beta turn between the two MSDs suggests that both the amino terminus and the carboxy terminus of Hol3626 might be located outside the cell membrane, a very unusual holin topology. Holin function was experimentally demonstrated by using the ability of the holin to complement a deletion of the heterologous phage λ S holin in λΔSthf. The endolysin gene ply3626 was cloned in Escherichia coli. However, protein synthesis occurred only when bacteria were supplemented with rare tRNAArg and tRNAIle genes. Formation of inclusion bodies could be avoided by drastically lowering the expression level. Amino-terminal modification by a six-histidine tag did not affect enzyme activity and enabled purification by metal chelate affinity chromatography. Ply3626 has an N-terminal amidase domain and a unique C-terminal portion, which might be responsible for the specific lytic range of the enzyme. All 48 tested strains of C. perfringens were sensitive to the murein hydrolase, whereas other clostridia and bacteria belonging to other genera were generally not affected. This highly specific activity towards C. perfringens might be useful for novel biocontrol measures in food, feed, and complex microbial communities.

Load carriage is a key risk factor for Muscular Skeletal Disorders (MSDs). As one way to decrease such injuries, some exoskeletons have been developed for regular load carriage. We examined the ergonomic potential of an augmentation exoskeleton. Nine subjects completed eight trials of carrying tasks, using four loading levels (0, 15, 30, and 45 kg) and two carrying conditions (with and without the exoskeleton). Electromyography (EMG) and the extended NASA-TLX rating scales were investigated and analyzed by linear mixed modeling and two-way ANOVA methods. Noraxon MR3.8, SPSS19.0, and MATLAB R2014b software were adapted. The results show that most of the muscle mean activities increased significantly (p < 0.05) with exoskeleton assistance. However, the interactive effects illustrate a decreasing trend with increase of load level. The mean discomfort rating scale values were generally higher, but subjects generally preferred using the exoskeleton in heavier loading tasks. The exoskeleton can effectively augment the performance of humans in heavy load carriage. The main reasons for higher muscle activity are from inflexible structures and inharmonious human–robot interactions. In order to decrease the MSD risks and increase comfort, optimal human–robot control strategies and adaptable kinematic design should be improved.

For the construction of an overexpression system of the intracellular 1,2-α-mannosidase (EC 3.2.1.113) gene (msdS) from Aspergillus saitoi (now designated Aspergillus phoenicis), the N-terminal signal sequence of the gene was replaced with that of the aspergillopepsin I (EC 3.4.23.18) gene (apnS) signal, one of the same strains as described previously. Then the fused 1,2-α-mannosidase gene (f-msdS) was inserted into the NotI site between P-No8142 and T-agdA in the plasmid pNAN 8142 (9.5 kbp) and thus the Aspergillus oryzae expression plasmid pNAN-AM1 (11.2 kbp) was constructed. The fused f-msdS gene has been overexpressed in a transformant A. oryzae niaD AM1 cell. The recombinant enzyme expressed in A. oryzae cells was purified to homogeneity in two steps. The system is capable of making as much as about 320 mg of the enzyme/litre of culture. The recombinant enzyme has activity with methyl-2-O-α-ᴅ-mannopyranosyl α-ᴅ-mannopyranoside at pH 5.0, while no activity was determined with methyl-3-O-α-ᴅ-mannopyranosyl α-ᴅ-mannopyranoside or methyl-6-O-α-ᴅ-mannopyranosyl α-ᴅ-mannopyranoside. The substrate specificity of the enzyme was analysed by using pyridylaminated (PA)-oligomannose-type sugar chains, Man9-6(GlcNAc)2-PA (Man is mannose; GlcNAc is N-acetylglucosamine). The enzyme hydrolysed Man8GlcNAc2-PA (type ‘M8A’) fastest, and ‘M6C’ {Manα1-3[Manα1-2Manα1-3(Manα1-6)Manα1-6]Manβ1-4GlcNAcβ1-4GlcNAc-PA} slowest, among the PA-sugar chains. Molecular-mass values of the enzyme were determined to be 63 kDa by SDS/PAGE and 65 kDa by gel filtration on Superose 12 respectively. The pI value of the enzyme was 4.6. The N-terminal amino acid sequence of the enzyme was GSTQSRADAIKAAFSHAWDGYLQY, and sequence analysis indicated that the signal peptide from apnS gene was removed. The molar absorption coefficient, ϵ, at 280 nm was determined as 91539 M-1·cm-1. Contents of the secondary structure (α-helix, β-structure and the remainder of the enzyme) by far-UV CD determination were about 55, 38 and 7% respectively. The melting temperature, Tm, of the enzyme was 71 °C by differential scanning calorimetry. The calorimetric enthalpy, ∆Hcal, of the enzyme was calculated as 13.3 kJ·kg of protein-1. Determination of 1 g-atom of Ca2+/mol of enzyme was performed by atomic-absorption spectrophotometry.

Occupational-specific classifications of musculoskeletal disorders (MSD) are scarce and do not answer specific clinical questions. Thus, a specific classification was developed and proposed, covering criteria applicable to daily clinical activity. It was considered that the disorder development process is the same across all work-related MSDs (WRMSDs). Concepts of clinical pathology were applied to the characteristics of WRMSDs pathophysiology, cellular and tissue alterations. Then, the correlation of the inflammatory mechanisms with the injury onset mode was graded into four levels (MSDs 0–3). Criteria of legal, occupational and internal medicine, semiology, physiology and orthopaedics, image medicine and diagnostics were applied. Next, the classification was analysed by experts, two occupational physicians, two physiatrists and occupational physicians and one orthopaedist. This approach will allow WRMSD prevention and improve therapeutic management, preventing injuries from becoming chronic and facilitating communication between occupational health physicians and the other specialities. The four levels tool relate aetiopathogenic, clinical, occupational and radiological concepts into a single classification. This allows for improving the ability to determine a WRMSD and understanding what preventive and therapeutic measures should be taken, avoiding chronicity. The developed tool is straightforward, easy to understand and suitable for WRMSDs, facilitating communication between occupational physicians and physicians from other specialities.

The incidence of work-related musculoskeletal disorders (MSDs) among dental workers has been increasing. Many ergonomic devices and accessories have been introduced. The aim of this study was to investigate the effects of an 8-figure shoulder brace on posture-related muscle activities in dental hygiene practitioners during scaling procedures. In this study, 33 participants (age: 21.9 ± 2.1 years, height: 162.0 ± 6.0 cm, weight: 55.8 ± 9.0 kg, body mass index: 21.2 ± 2.4 kg/m2) performed the scaling procedure with and without the 8-figure shoulder brace in a randomized order. The normalized electromyography activity in the amplitude probability distribution function and joint angles (cervical, thoracic, lumbar, and shoulder joints) were simultaneously recorded during scaling. A paired t test was used to compare the differences in muscle kinematics, with the alpha level set at 0.05. The dental hygienists who wore the 8-figure shoulder brace during scaling showed thoracic and lumbar extension, improved sitting postures, and reduced shoulder joint abduction. However, we also observed an unintended increase in internal rotation. Use of the 8-figure shoulder brace could prevent work-related MSDs in lumbar and thoracic regions by reducing the effort exerted by the upper trapezius and deltoid muscles, despite the increased muscular effort of the cervical erector spinae.

Abstract. Agricultural workers perform tasks that frequently require awkward and extreme postures that are associated with musculoskeletal disorders (MSDs). The PATH (Posture, Activity, Tools, Handling) system currently provides a sound methodology for quantifying workers’ exposure to these awkward postures on an ordinal scale of measurement, which places restrictions on the choice of analytic methods. This study reports a modification of the PATH methodology that instead captures these postures as degrees of flexion, an interval-scaled measurement. Rather than making live observations in the field, as in PATH, the postural assessments were performed on photographs using ImageJ photo analysis software. Capturing the postures in photographs permitted more careful measurement of the degrees of flexion. The current PATH methodology requires that the observer in the field be trained in the use of PATH, whereas the single photographer used in this modification requires only sufficient training to maintain the proper camera angle. Ultimately, these interval-scale measurements could be combined with other quantitative measures, such as those produced by electromyograms (EMGs), to provide more sophisticated estimates of future risk for MSDs. Further, these data can provide a baseline from which the effects of interventions designed to reduce hazardous postures can be calculated with greater precision. Keywords: Ergonomic assessment, Farmworkers, Interval-scaled data, Musculoskeletal disorders.

Antropometri merupakan studi tentang pengukuran fisik tubuh manusia, mengenai dimensi bentuk serta ukuran tubuh yang dapat digunakan dalam klasifikasi dan perbandingan antropologis. Antropometri digunakan sebagai pertimbangan ergonomis dalam proses perancangan desain produk. Sekolah Dasar Negeri 17 Pekanbaru sudah memiliki meja dan kursi yang jumlahnya cukup sesuai dengan kebutuhan siswanya. Namun, dalam implementasi antropometrinya belum sesuai dengan dimensi tubuh siswa tersebut, ukuran tubuh siswa yang tidak sama dengan ketersediaan meja dan kursi sehingga sangat mengganggu siswa dalam kenyamanan duduk dikelas, terdapat siswa yang merasakan keluhan nyeri punggung ketika mengikuti proses pembelajaran selama dikelas, nyeri pada leher, pergelangan tangan dan bagian tubuh lainnya, hal ini dikarenakan kursi yang tidak sesuai dengan ukuran dimensi tubuh siswa tersebut. Kegiatan ini bertujuan untuk menganalisis secara antropometri postur tubuh siswa, ketinggian meja belajar dan desain kursi belajar siswa yang ergonomis terhadap pencegahan Muskuloskeletal Disorders. Kegiatan dilakukan dalam bentuk promosi Kesehatan yang diikuti oleh siswa dengan menerapkan protokol kesehatan pada waktu kegiatan tatap muka terbatas disekolah. Metode yang digunakan adalah ceramah dan diskusi dengan peserta penyuluhan dengan luaran kegiatan artikel pengabdian masyarakat. Abstrak Anthropometry is the study of the physical measurements of the human body, regarding the dimensions of body shape and size that can be used in anthropological classification and comparison. Anthropometry is used as one of the ergonomic considerations in the design process. SDN 17 Pekanbaru already has a sufficient number of tables and chairs according to the needs of its students. However, the implementation of anthropometry is not in accordance with the dimensions of the student's body, the size of the student's body that is not the same as the availability of tables and chairs greatly interferes with students sitting comfortably in class. There are students who feel complaints of back pain when participating in the learning process during class, such as pain in the neck, wrist, and other body parts. This is because the chair does not match the dimensions of the student's body. This activity aims to analyze students' posture anthropometry, height and design of ergonomic student desks and chairs for the prevention of Musculoskeletal Disorders. The activity was carried out in the form of counseling which was attended by students by implementing health protocols when face-to-face activities were limited at school. The method used was lectures and discussions with the output of community service article. The results of this activity were known that the design conditions of the tables and chairs were still not in accordance with the dimensions of the student's body shape, causing complaints about disturbances in MSD's. In conclusion, one of the efforts that can be made to avoid MSD's complaints is when students sit, pay attention to their position and how to sit. They should not sit in a bent position, tilt to the left or right, and often do stretching movements

Objective: Musculoskeletal disorders which leads to the pain in the neck, shoulder, upper back, lower back, knee or other skeletal areas, are instances of musculoskeletal strains. Musculoskeletal problem is the main region of morbodity and the seconldy cause of disability in all world. Any action of the body involving the skeletal muscles that results in a modest to high energy expenditure is referred to as physical activity (PA). This study's aim was to determine the prevalence of musculoskeletal illnesses and how physical activity among senior age groups relates to those disorders. This study aimed to determine the prevalence of musculoskeletal disorders, the level of physical activity using a short-form physical activity questionnaire, and the relationship between the prevalence of these disorders and physical activity. Material and Methods: From October 2021 to August 2022, a cross-sectional study of 152 geriatric patients in a rural Wardha was conducted using pre-structured and pre-designed questionnaires. These included demographic information, a short form of the International Physical Activity Questionnaire to gauge the level of physical activity, and standardized Nordic questionnaires to examine musculoskeletal symptoms. Results: Our survey shows 95.3% of elderly people reported musculoskeletal problems. The age groups 60-70 years of geriatrics had the highest prevalence of MSDs (55.19%), significantly higher than those of 70-80, 80-90, and 90-100 years of geriatrics (p 0.05). There is a substantial correlation between the degree of physical activity and the musculoskeletal disorder; the majority of the participant had a moderate level of physical activity (55.9%), with the knee being the most frequently reported region (61.18%). Conclusions: In this study, there are more musculoskeletal diseases among female individuals from rural Wardha than among male participants. Geriatrics between the ages of 60 and 70 had a higher MSD prevalence than those between the ages of 70- 80 or 80-90. The body component most affected was the knee, followed by the lower back and upper back. The majority of the affected senior population engaged in moderate physical activity
