||Follow-up of neck and shoulder pain among sewing machine operators: The Los Angeles Garment Study
||2010, Vol.53, p.352-360. Illus. 27 ref.
||The aim of this study was to explore factors affecting or modifying self-reported neck/shoulder pain in 247 sewing machine operators who participated in a 4-month prospective intervention study for musculoskeletal disorders. All participants were immigrants. The influence of individual and work-related factors on changes in neck/shoulder pain were examined during follow-up using linear mixed models with time-spline functions. A dramatic decline (72%) in self-reported pain intensity was observed in the first month of follow-up, followed by a small increase from the first to fourth month (4% per month). Workers who perceived and reported their physical workload as high or who worked overtime experienced less overall pain reduction. Higher baseline pain intensity, being of Hispanic ethnicity (as opposed to Asian), and taking cumulative daily rest time during work of 35 min or more allowing for muscles to rest were associated with a larger pain reduction in the first month, but not thereafter. Findings indicate that some work-related factors may be of clinical relevance for reducing neck/shoulder pain. Having lower physical workloads and less overtime work should be considered when treating patients or planning workplace interventions for managing work-related musculoskeletal disorders in this underserved immigrant population.
