Work-related musculoskeletal disorders and ergonomic risk factors in early intervention educators

BackgroundEarly intervention educators who serve children with special needs often suffer from physical strains. The objectives of this study were to investigate the prevalence of work-related musculoskeletal disorders in this population, and to evaluate the relationship between work-related musculoskeletal disorders and personal/ergonomic risk factors.MethodsA self-designed questionnaire consisting three domains (demographics/prevalence of work-related musculoskeletal disorders/ergonomic risk factors) was delivered to educators who work in early intervention institutions.ResultsNinety-four percent of early intervention educators suffered from musculoskeletal disorders. Logistic regression revealed that some work-related ergonomic factors were highly associated with symptoms on lower back, shoulder and neck, with odds ratios ranging from 0.321 to 4.256.ConclusionHigh prevalence of work-related musculoskeletal disorders impacts this occupation negatively. Further regulations to the institutions regarding workplace health promotion and environment modification, as well as training to the employees for body mechanics, should be implemented to prevent injury occurrence.

► Results indicated the prevalence of WMSDs was high.
► Some ergonomic factors were associated with symptoms on lower back, shoulder and neck.
► Results provide guidelines regarding safe children handling and health awareness.
► Modifications and ameliorations of the work-related features are of great demand.
