title: Activity restriction among wheelchair users.
abstract: OBJECTIVE
  To identify factors associated with activity restriction.
  
  
  METHODS
  Cohort study.
  
  
  METHODS
  Patients prescribed a new wheelchair at one of two teaching hospitals (one Veterans Affairs and one private hospital).
  
  
  METHODS
  One hundred fifty-three consecutive, community-dwelling wheelchair users, who had a Short Portable Mental Status Score greater than 6 out of 10 and could be interviewed within 7 to 21 days of receiving the wheelchair.
  
  
  METHODS
  Dependent variables were self-reported nonmedical visits and medical visits in the preceding week (any vs no visits and the number of visits). Independent variables were self-reported sociodemographic and health characteristics, mobility limitations, and environmental barriers.
  
  
  RESULTS
  Study subjects reported, on average, 1.79 mobility limitations, 11.17 hours out of bed, and 5.56 hours of personal assistance per day. Multivariate analyses show that higher income was the only significant sociodemographic factor; it was associated with more medical visits (beta=0.44, P<.01). Of health status characteristics, more comorbid conditions predicted fewer nonmedical visits (beta=-0.14, P<.10) and amputation was associated with fewer medical visits (beta-0.82, P<.05). Regarding mobility limitations, more mobility limitations was associated with lower odds of any nonmedical visit (odds ratio (OR)=0.71, P<.5) and fewer nonmedical visits (beta=-0.28, P<.05); more hours out of bed predicted more nonmedical visits (beta=0.05, P<.5) and lower odds any medical visit (OR=0.92, P<.05). More environmental barriers predicted fewer nonmedical (beta=-0.32, P<.01) or medical visits (beta=-0.21, P<.05).
  
  
  CONCLUSIONS
  Mobility limitations and environmental barriers were associated with restricted participation in diverse activities outside the home.
