abstract: Chan DK, Lonsdale C, Ho PY, Yung PS, Chan KM. Patient motivation and adherence to postsurgery rehabilitation exercise recommendations: the influence of physiotherapists' autonomy-supportive behaviors.
  
  
  OBJECTIVE
  To investigate the impact of physiotherapists' autonomy-supportive behaviors on patients' motivation and rehabilitation adherence after anterior cruciate ligament (ACL) reconstruction surgery.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  Outpatient orthopedic clinic of a university medical center.
  
  
  METHODS
  Postsurgery ACL reconstruction patients (N=115; minimum postsurgery interval, 6mo; mean +/- SD postsurgery interval, 1.77+/-0.8y).
  
  
  METHODS
  Not applicable.
  
  
  METHODS
  Questionnaires measuring autonomy support from physiotherapists (Health Care Climate Questionnaire), treatment motivation (Treatment Self-Regulation Questionnaire), and rehabilitation adherence (adapted from the Sport Injury Rehabilitation Adherence Scale and the Patient Self-Report Scales of Their Home-Based Rehabilitation Adherence).
  
  
  RESULTS
  Structural equation modeling analyses revealed that patients' treatment motivation mediated the relationship between physiotherapists' autonomy-supportive behaviors and rehabilitation adherence. Autonomy-supportive behavior positively predicted autonomous treatment motivation (beta=.22, P<.05). Rehabilitation adherence (R(2)=.28) was predicted positively by autonomous motivation (beta=.64, P<.05) and negatively predicted by controlled motivation (beta=-.28, P<.05).
  
  
  CONCLUSIONS
  These preliminary findings are promising and provide an empirical basis for further research to test the efficacy of autonomy support training designed to increase patients' rehabilitation adherence.
