title: Effectiveness of a bed positioning program for treating older adults with knee contractures who are institutionalized.
abstract: OBJECTIVE
  Although contractures in patients in long-term care institutions are an important issue, there have been only a few studies that have evaluated interventions for contractures. The purpose of this study was to determine the effectiveness of a bed positioning program (BPP) for the treatment of patients with knee flexion contractures.
  
  
  METHODS
  Sixteen patients with a high level of cognitive and functional impairment (mean age=82 years, SD=6.48, range=71-93) in a chronic care hospital participated in the study.
  
  
  METHODS
  The BPP consisted of stretching a patient's knee into extension and then securing and maintaining the position for a period of 40 minutes, 4 times per week. Participants were randomly assigned to 2 groups (n=8 in each group). One group received a BPP for 8 weeks, followed by 8 weeks of no intervention. The other group received the intervention in the reverse order. Once a week, participants were assessed for range of knee extension, knee pain, and skin integrity.
  
  
  RESULTS
  Twelve participants completed the study. There was no improvement in participants' range of knee extension during the intervention period. Overall, there was no difference in mean range of knee extension between the intervention period and the no-intervention period.
  
  
  CONCLUSIONS
  The results of this study do not support the use of a BPP for treating patients with knee flexion contractures.
