title: Work-related musculoskeletal disorders in physical therapists: a prospective cohort study with 1-year follow-up.
abstract: BACKGROUND
  Work-related musculoskeletal disorders (WMSDs) have a significant impact on physical therapists, but few studies have addressed the issue. Research is needed to determine the scope of the problem and the effects of specific risk factors.
  
  
  OBJECTIVE
  The objectives of this study were: (1) to determine the 1-year incidence rate of WMSDs in physical therapists and (2) to determine the effects of specific risk factors.
  
  
  METHODS
  This was a prospective cohort study with 1-year follow-up.
  
  
  METHODS
  Subjects were randomly selected American Physical Therapy Association members (N=882). Exposure assessment included demographic data, physical risk factors, job strain, and specific physical therapy tasks. The primary outcome was WMSDs, with a severity rating of at least 4/10 and present at least once a month or lasting longer than a week.
  
  
  RESULTS
  The response rate to the baseline questionnaire was 67%. Ninety-three percent of the subjects who responded to the baseline questionnaire responded to the follow-up questionnaire. The 1-year incidence rate of WMSDs was 20.7%. Factors that increased the risk for WMSDs included patient transfers, patient repositioning, bent or twisted postures, joint mobilization, soft tissue work, and job strain.
  
  
  CONCLUSIONS
  The primary limitation of this study was the number of therapists who had a change in their job situation during the follow-up year.
  
  
  CONCLUSIONS
  Work-related musculoskeletal disorders are prevalent in physical therapists. Physical therapy exposures, patient handling, and manual therapy, in particular, increase the risk for WMSDs.
