- Objectives
The prevalence of cumulative trauma disorders of upper extremities mons watch assembly workers in small-scaled industry was studied.
Methods
In 83 workers at five watch assembly factories, symptoms and psychosocial questionnaire, ergonomic Interview, physical examination were conducted.
Results
Prevalence of self-reported symptoms was 54.2% and neck 34.9%, wrist/hand 31.3%, shoulder 30.1%, elbow/arm 18.0% by anatomical site. Prevalence of cumulative trauma disorders was 45.8%. Most common disease was myofascial pain syndrome (31.3%). The other diseases were De Quervain disease (9.6%), tenosynovitis/tendinitis at wrist/hand (9.6%), bicipital tendinitis(6.0%), fat. epicondylitis(4.8%), meIn. epicondylitis(2.4%), and cervical disc disease(2.4%). As result of ergonomic interview, repetitiveness was 79(98.8%). There were no differences in the prevalence of self-reported symptoms and cumulative trauma disorders for age, sex, marital status, duration of work In the study, The significant factors of cumulative trauma disorders were occupational task and psychosocial stress in the study. The prevalence of cumulative trauma disorders in high strain group was hlgher (68.4%) than other three groups. The prevalence of self-reported symptoms and cumulative trauma disorders in assembly task was higher (70.0%, 64.0%) than other two tasks.
Conclusions
Prevalence of self-reported symptoms was 54.2%, prevalence of cumulative trauma disorders was 45.8% in watch assembly workers. In this study, factor related to self-reported symptoms was occupational task and factors relaxed to cumulative trauma disorders were occupational task and psychosocial stress. This results suggest that differences of ergonomics and environment in occupational task cause differences of prevalence of self-reported symptoms and cumulatlve trauma disorders.
