title: Therapeutic exercise and orthopedic manual therapy for impingement syndrome: a systematic review.
abstract: OBJECTIVE
  To review randomized controlled trials evaluating the effectiveness of therapeutic exercise and orthopedic manual therapy for the treatment of impingement syndrome.
  
  
  METHODS
  Reports up to October 2002 were located from MEDLINE, the Cochrane Database of Systematic Reviews, the Physiotherapy Evidence Database (PEDro), the TRIP database, and the Cumulative Index to Nursing & Allied Health Literature (CINAHL) using "shoulder" and "clinical trial"/"randomized controlled trial" as search terms.
  
  
  METHODS
  Studies were included if (1) they were a randomized controlled trial; (2) they were related to impingement syndrome, rotator cuff tendinitis, or bursitis; (3) one of the treatments included therapeutic exercise or manual therapy.
  
  
  METHODS
  Two independent observers reviewed the methodological quality of the studies using an assessment tool developed by the Cochrane Musculoskeletal Injuries Group. Differences were resolved by consensus.
  
  
  RESULTS
  Seven trials met our inclusion criteria. After consensus, the mean methodological score for all studies was 13.9 +/- 2.4 (of 24). Four studies of 7, including the 3 trials with the best methodological score (67%), suggested some benefit of therapeutic exercise or manual therapy compared with other treatments such as acromioplasty, placebo, or no intervention.
  
  
  CONCLUSIONS
  There is limited evidence to support the efficacy of therapeutic exercise and manual therapy to treat impingement syndrome. More methodologically sound studies are needed to further evaluate these interventions.
