Stretch for the treatment and prevention of contracture: an abridged republication of a Cochrane Systematic Review

Question: Is stretch effective for the treatment and prevention of contractures in people with neurological and non-neurological conditions? Design: A Cochrane Systematic Review with meta-analyses of randomised trials. Participants: People with or at risk of contractures. Intervention: Trials were considered for inclusion if they compared stretch to no stretch, or stretch plus co-intervention to co-intervention only. The stretch could be administered in anyway. Outcome measures: The outcome of interestwas joint mobility. Two sets of meta-analyses were conducted with a random-effects model: one for people with neurological conditions and the other for people with non-neurological conditions. The quality of evidence supporting the results of the two sets of meta-analyses was assessed using GRADE. Results: Eighteen studies involving 549 participants examined the effectiveness of stretch in people with neurological conditions, and provided useable data. The pooled mean difference was 2 deg (95% CI 0 to 3) favouring stretch. This was equivalent to a relative change of 2% (95% CI 0 to 3). Eighteen studies involving 865 participants examined the effectiveness of stretch in people with non-neurological conditions, and provided useable data. The pooled standardised mean difference was 0.2 SD (95% CI 0 to 0.3) favouring stretch. This translated to an absolute mean increase of 1 deg (95% CI 0 to 2) and a relative change of 1% (95% CI 0 to 2). The GRADE level of evidence was high for both sets of meta-analyses. Conclusion: Stretch does not have clinically important effects on joint mobility. (C) 2017 Australian Physiotherapy Association. Published by Elsevier B. V.
