Exercise Therapy for Treatment of Acute Non-specific Low Back Pain: A Cochrane Systematic Review and Meta-analysis of Randomized Controlled Trials.

Exercise therapy compared with sham/placebo and no treatment may have no clinically relevant effect on pain or functional status in the short term in people with acute non-specific LBP, but the evidence is very uncertain. Owing to insufficient reporting of adverse events, we were unable to reach any conclusions on the safety or harms related to exercise therapy.
