“…There was a total of 37,845 participants in 18 studies reporting on physically active workers. The prevalence estimates or odds ratios in those over 50 increased in 14 of these 18 studies [ 13 , 14 , 21 , 23 , 25 , 29 – 31 , 34 – 39 ], remained stable in two [ 22 , 28 ] and decreased in one [ 24 ]. One study of farmers reported data only for two age groups, using 65 as a cut point and found that shoulder pain reporting decreased in the older group [ 33 ].…”

Background Shoulder pain was previously shown to diminish in older populations and it was suggested that this could be explained by reduced usage with age. Our objectives were to investigate if estimates of shoulder pain continue to increase after the age of 50 in working populations and to compare these estimates in physically demanding occupations with sedentary occupations. Methods A systematic review of retrospective, cross-sectional, prospective, or longitudinal. studies reporting prevalence or incidence of non-specific shoulder pain in occupational groups stratified by age. Searches were conducted in PubMed, Scopus, and CINAHL from inception until January 2020. Study characteristics and prevalence estimates stratified by age were extracted. Two reviewers independently performed a critical analysis of the included studies to determine their validity and risk of bias. Results Twenty studies with a total of 40,487 participants and one study of a clinical data base were included and assigned a direction of the estimates for shoulder pain as either ‘increasing’, ‘remaining stable’ or ‘decreasing’ past the age of 50. Shoulder pain generally increased past 50, with 16 of the 21 included studies reporting higher estimates/odds ratios in older participants. In the more physically active occupations over 50, the estimates increased in 14 of the 18 samples compared to only two of the four involving sedentary occupations. Conclusions Shoulder pain prevalence remains common in workers beyond the age of 50. Prevalence continues to increase in physically demanding occupations. Clinicians should consider factors of occupation when managing shoulder pain. Trial registration PROSPERO (CRD42019137831).

“…Previous studies have measured the level of physiological stress experienced by cameramen in terms of heart rate and oxygen consumption and classified cameramen’s tasks as physiologically heavy work [ 15 ], analyzed occupational suprascapular nerve entrapment among cameramen [ 22 ], and identified ergonomic factors and physical burden as risk factors of WRMDs in cameramen, which were found to affect the shoulders most commonly [ 14 ]. However, these studies limited their research subjects to cameramen only.…”

“…In addition, workplace factors (e.g., time pressure, poor work/rest schedule, and low job control), physical factors (e.g., old age and elevated body mass index), and psychosocial stress have also been reported as risk factors of WRMDs [ 13 ]. A study has reported that these ergonomic risk factors are present in workplaces for cameramen and that they affect the incidence of WRMDs among cameramen [ 14 ]. Another study has reported that because cameramen perform physically demanding tasks and thus experience high levels of physiological stress, their occupation must be classified as heavy work [ 15 ].The environment for making TV programs in Korea lacks production costs and staff, giving cameramen long working hours and short break times.…”

BackgroundPrevious studies have classified cameramen’s job as physiologically heavy work and identified the risk factors of work-related musculoskeletal disorders (WRMDs) in cameramen. However, those studies limited their research subjects to cameramen. In this study, we compared the frequency and severity of WRMDs between cameramen and office workers.MethodsA total of 293 subjects working in four broadcasting companies in Korea were recruited. A questionnaire survey was conducted for a month, starting in October 2016. The subjects were divided into cameramen and office workers according to their occupation. We compared the frequency and severity of WRMDs and ergonomic risk assessment results between the two groups.ResultsThe high-risk WRMD group had a higher proportion of cameramen than office workers. Moreover, the high ergonomic risk group also had a higher proportion of cameramen than office workers for WRMDs in the upper extremities and waist+lower extremities. In the multivariable-adjusted model comparing cameramen and office workers, the odds ratio (OR) with 95% confidence interval (95% CI) for high-risk WRMDs was 3.50 (95% CI: 1.92–7.72) for the upper extremities and 3.18 (95% CI: 1.62–6.21) for the waist and the lower extremities. The ORs by body parts were 3.11 (95% CI: 1.28–7.57) for the neck, 3.90 (95% CI: 1.79–8.47) for the shoulders, and 4.23 (95% CI: 1.04–17.18) for the legs and feet.ConclusionsOur study suggests that cameramen are at high risk of WRMDs. Workplace improvements and management of the neck, shoulders, and lower extremities, which are susceptible to WRMDs, are necessary to prevent musculoskeletal disorders among cameramen.

“…To the best of our knowledge, fewer studies reported the relationship between BMI and EMG signal variations. Indeed, BMI was associated with increased prevalence of work-related musculoskeletal disorders (WMSDs) and increased scores of musculoskeletal discomfort [40,41]. It may be necessary to investigate the longer term effects of BMI on muscle activation in future work since BMI influences chronic musculoskeletal pain/discomfort in a roundabout way [42].…”

Background: Sit-stand workstations are available for office work purposes but there is a dearth of quantitative evidence to state benefits for lower limb outcomes while using them. And there are no guidelines on what constitutes appropriate sit/stand time duration. The primary aim of this study has been to compare muscle activity and perceived discomfort in the lower extremity during various combinations of sit/stand time duration associated with a sit-stand workstation separately and to evaluate the effects of the sit-stand workstation on the lower extremity during the text entry task. Material and Methods: During the 5 days, all participants completed a 2-h text entry task each day for various sit/stand time duration combinations as follows: 5/25 min, 10/20 min, 15/15 min, 20/10 min, 25/5 min. Lower extremity muscular exposure of 12 male and 13 female participants was collected at 8 sites by surface electromyography and body discomfort was calculated by a questionnaire under those 5 conditions. Results: Results have demonstrated that lower extremity muscle activity has been significantly varied among the 5 sit/stand time duration groups. Perceived level of discomfort (PLD) has not differed significantly for 9 out of 10 body parts. Conclusions: The muscle activity of the thigh region was influenced by sit/stand time duration significantly. Ergonomic exposures of lower extremity when using a sitstand workstation were increased, particularly during the long time standing posture. Results indicate that body mass index (BMI) and gender were not significant factors in this study. Combination of sit/stand time duration 25/5 min appears to show positive effects on relief of muscle exposure of back of thigh in the shifts of sitting and standing work position.
