Journal of Primary Care & Community Health 12 (January 2021): 215013272110403. http://dx.doi.org/10.1177/21501327211040359.
Full textAbstract:
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.

Full textAbstract:
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.

Full textAbstract:
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.

Full textAbstract:
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.

Full textAbstract:
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.

Full textAbstract:
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.

Full textAbstract:
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.

Full textAbstract:
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.

Preventive responses most often made to caregivers are too often "gestures and postures training" type to reduce these occupational hazards. Taking the party to focus on manual handling of patients (MMP), it seemed appropriate to revisit prevention measures being implemented by combining the results of international standardization and reflections on the organization of work. The approach described above has found its place in the training actions in applied ergonomics and prevention of risks related to physical activity for caregivers and their management. The objective is to convey to employees, tools for evaluation of work situations, adapted to their activity for taking into account the ergonomics for reducing the risk occurrence of MSDs. Such an approach fit into the development of working group and the cross disciplinary organizations.

Full textAbstract:
Musculoskeletal disorders (MSDs) are the most frequent occupational health problem in the European Union where they have physical and economic consequences for workers, their families, companies, and the government. According to the European Agency for Safety and Health at Work (EU-OSHA), MSDs seem to be prevalent in construction, mining, and industry. These injuries are frequent in work situations where there is exposure to work activity risk factors, such as: standing posture for long periods of time, awkward joint postures (e.g., bending and twisting), repetitive movements, application of hand and finger force, exposure to vibrations and cold, manual handling of loads or no recovery periods between tasks. In this study, an Ergonomic Work Analysis (EWA) was carried out to understand the working conditions of workers at the MCG transportation factory unit, making part of metalworking industry, in Portugal. The objectives of the study were: the characterization of the metalworking industry regarding the risk of developing MSDs, the characterization of musculoskeletal symptoms self-reported by workers, the identification of the most problematic risk factors concerning each task assessed and, finally, the definition of an action plan to solve the identified problems. To characterize the tasks and workers, several methods/techniques were used, namely, free/systematized observations, non-structured interviews with workers, image/video recording and a questionnaire (adapted from the Nordic Musculoskeletal Questionnaire) specifically developed for this purpose. To assess and quantify the risk of developing MSDs, different methods, such as Rapid Entire Body Assessment (REBA), Rapid Upper-Limb Assessment (RULA), Revised NIOSH lifting equation, Revised Strain Index), ACGIH Hand Activity Level and the 2D Biomechanics, were used, to accommodate the specificities of each task. For data processing the SPSS© software was used and descriptive analyses were performed using measures of location and dispersion. The Chi-square test and Cramer’s V coefficient were used to assess associations between variables (demographic/work-related characteristics) and reported MSD symptoms. A significance level of 0.05 was adopted as a criterion to reject the null hypothesis. For the application of the above-mentioned methods the ErgoWeb EnterpriseTM software was used. All workers (N=18) agreed to participate in the study and the privacy of each participant was respected. Ten tasks were analyzed and assessed. Overall, the body regions with the highest percentage of complains were lower back (83,3%), neck (50%), upper limbs (hand/fist (50%) and shoulders (44,5%)). The results obtained corroborated data obtained from several studies. There was a positive association between work demands and complaints of pain in various body regions. Considering the postural assessment methods, all tasks presented a risk of developing musculoskeletal injuries (Risk level > 2). Through the application of the method of evaluating the physical demands associated with the tasks of manual handling of loads, it was verified that the weight of the loads is above the recommended, and therefore, the tasks presented a risk of developing injuries at the level of the lumbar spine (IL > 1). All these results show that investigations and measures to improve working conditions must be carried out.

"What is the repercussions of the introduction of a cobot on productivity and biomechanical constraints on operators in a collaborative task?" In 14th International Conference on Applied Human Factors and Ergonomics (AHFE 2023). AHFE International, 2023. http://dx.doi.org/10.54941/ahfe1003042.
Full textAbstract:
Collaborative robots, or cobots, are robots designed to closely collaborate with a human in a shared workplace. Introducing a cobot in a collaborative work situation aims to preserve productivity without impair the operator’s health, even improve them. Musculoskeletal disorders (MSDs), main occupation diseases in Industry, are pathologies of multifactorial origin, as biomechanical solicitations are one of them (e.g., posture, repetitiveness).This paper evaluates the repercussions of the introduction of a cobot in a collaborative task with two studies: first to compare a task in collaboration with a cobot or a human co-worker and second to analyze the impact of pace (i.e., rhythm and leader); both on productivity, quality of interactions, operator’s posture and attentional demand.Thirty-four participants in Study 1 and twenty in Study 2 performed a collaborative task inspired by assembly lines in factories, in collaboration with a co-worker. In Study 1, this co-worker was either a human or a YuMi cobot, participants were always the leader; in Study 2, the co-worker was always the YuMi cobot; the leader was either the participants or the cobot, and in this last case, different paces were imposed. Productivity was measured with the number of products manufactured, quality interactions with the rate of idleness and activity of participant and co-worker and interactions rate between them, participant’s posture with joints angles and RULA evaluation and attentional demand with performance at a second task.In Study 1, productivity was less important with the cobot than with a human, with less interactions and with higher attentional demand. However, posture was less risky with the cobot for operator health in terms of MSDs. In Study 2, productivity and attentional demand increased with the pace until a threshold at the mean-imposed pace. Posture was riskier for operator health in terms of MSDs only for the fastest imposed pace.In Study 1, deterioration of productivity and quality of the interactions with the cobot co-worker was mainly due to the limited capabilities of the cobot. Results about posture were also linked with pace, but differences were also observed during operator’s activity with less biomechanical solicitations working with the cobot than with the human for the same actions. Leading or following the pace seemed to not influence these variables in Study 2. Thus, the results of Study 2 seemed to indicate that the differences between human-human and human-cobot interactions observed in Study 1 were mainly due to the slower pace due to the cobot, except for the better posture which could be linked with the introduction of the cobot.Even though the experiment took place in a laboratory, the task was strongly inspired by the field and the results are consistent with those in the literature. These results therefore allow us to establish solid hypotheses that can be generalized to real situations in a factory, especially concerning the improvement of the posture when the operator is facing a cobot.

Full textAbstract:
A survey of the Thai National Statistical Office in 2012 indicated the number of informal employment was about 24.8 million, which was as high as 62.6% of the total number of employed persons (39.6 million persons) in . Considered by the work regions, the informal employment mostly worked in the Northeast of Thailand, approximately 41.5% of all informal workers. In general, these workers are rice farmers who involve rice cultivation processing as their main occupation. Previous studies found most of them to have rice basketwork as the major supplement of career. Most tasks in rice basketwork are performed with prolonged sitting on the floor and using repetitive movements of hands, fingers, wrists and shoulders for more than 6 hours a day, were likely to increase the musculoskeletal disorders (MSDs). A task analysis was conducted on basketwork tasks at a large area in the Khon Kaen and was then used to structure a job screening for ergonomics-related risk factors. The basketry process was divided in to six steps, including: 1) scrape bamboo skin, 2) cut a piece of bamboo, 3) tear strips of bamboo, 4) sharpen the bamboo, 5) weave the strips of bamboo and, 6) form the rice basket. The activities in each step were associated with different tools, for example, some steps included using a knife to slit bamboo or a bamboo cylinder for lifting. Subjective ratings of risk of injury, as part of job screening, were then made for each basketry step in each body part, focusing on motion, force, and posture. The screening tool used in this study was based on the Hand Activity Level (HAL) and Rapid Upper Limb Assessment (RULA) methodologies. The screening results revealed worker exposure to repetitive motion, high forces and extreme postures at the neck, shoulders, hands, and legs when performing in each step of basketry. The results indicated the basketwork procedure to pose ergonomics risk to workers. The highest risk was due to awkward work postures. Results also revealed continuously repetitive motion of upper limbs for long periods of time and inappropriately use of load and force at upper body parts. Therefore, this study suggested that ergonomics interventions, using engineering, administration and/or personal protection controls, should be applied in order to reduce risk of occupational injury of informal workers in .

Full textAbstract:
The increased automation of the car manufacturing process, in which much of the assembly has been delegated from man to machine, has done much to relieve workers of the burden of heavy lifting. However, despite ergonomic improvements in the workplace, many jobs still require workers to perform repetitive tasks [1]. In the automotive industry, Work-related Musculoskeletal Disorders (WMSD) are one of the most common occupational problems due to repetitive working tasks. Workers that perform manual work are often prone to awkward postures, repetitive movements, forceful exertions, and overextensions, which are some of the main factors for the arising of WMSD [2]. Besides, these work-related factors, also the personal factors contribute to the occurrence of this kind of injury, making WMSD a complex condition that involves contributions from many factors [3,4]. The current study aims to compare different observational methods commonly used to assess the WMSD risk in repetitive tasks. To accomplish this goal a case of study in assembly workstation of an automotive company in Portugal was applied. It was selected methods that are widely used by ergonomists and are validated for implementation in the industry [5,6]. Therefore, the following methods were applied to an assembly workstation: (i) Rapid Upper-Limb Assessment (RULA), (ii) Occupational Repetitive Actions (OCRA), (ii) Key Indicator Method – Manual Handling Operations (KIM-MHO), and (iv) Revised Strain Index (RSI) This multi-method approach was very important, as it allowed for a more comprehensive assessment, which will support the proposals for improvement The results show that workstation present a considerable WMSD risk in 3 of 4 methods applied. These results suggest that a change to the workstation is necessary. A possible solution would be to implement a Human-robot collaboration solution, in order to reduce the physical demands associated with repetitive movements [7] to which workers are subjected.
