Musculoskeletal symptoms among sewing machine operators

Computer users’ risk factors for developing shoulder, elbow and back symptoms

“…In comparison with the design of previous cross-sectional studies, this approach offered the possibility to identify predictors of increased symptoms. People who change jobs are more likely to be relieved of their pain (25). In order to control for exposure at follow-up, we repeated the use of the final model for each of the three regions including only the workers who, in the follow-up questionnaire, had not changed jobs since the baseline examination.…”

Validity of a self-completed questionnaire measuring the physical demands of work

“…The high prevalence of musculoskeletal disorders in physically demanding occupations is a well documented feature of both cross-sectional surveys (1)(2)(3) and cohort studies (4,5). Physical occupational exposures that might be associated with such symptoms have typically been classified indirectly using job titles (6)(7)(8).…”

Subjective symptoms among motorcycling traffic policemen

“…Assessing the prevalence of subjective symptoms from the median value of motorcycle riding experience revealed that the high-exposure subgroup in group A had higher prevalence rates for all the symptoms (table 2). In a longitudinal study, Schibye et a1 (5) reported that symptomatic sewing machine operators who changed jobs were much more likely to be relieved of their symptoms than were symptomatic operators who continued sewing. In a historical cohort study, Anderson & Gaardbore (6) showed that current sewing machine operators had about a 2-fold higher risk of neck and shoulder pain than those who stopped sewing.…”
