Exercise interventions for the treatment of chronic low back pain: a systematic review and meta-analysis of randomised controlled trials

To determine, for adults with chronic low back pain, which exercise interventions are the most effective at reducing pain compared to other treatments. DATA SOURCES: A search of MEDLINE, CINAHL, EMBASE, SPORTDiscus, PsycINFO and The Cochrane Library was conducted up to October 2014. REVIEW METHODS: Databases were searched for published reports of randomised trials that investigated the treatment of chronic low back pain of non-specific origin with an exercise intervention. Two authors independently reviewed and selected relevant trials. Methodological quality was evaluated using the Downs and Black tool.

Forty-five trials met the inclusion criteria and thirty-nine were included in the meta-analysis. Combined meta-analysis revealed significantly lower chronic low back pain with intervention groups using exercise compared to a control group or other treatment group (Standard Mean Deviation (SMD) =-0.32, CI 95% -0.44 to -0.19, P
