Walking, Cycling, and Swimming for Nonspecific Low Back Pain: A Systematic Review With Meta-analysis.

Abstract

To investigate the effectiveness of walking/running, cycling, or swimming for treating or preventing nonspecific low back pain (LBP). Intervention systematic review. Five databases were searched to April 2021. Randomized controlled trials evaluating walking/running, cycling, or swimming to treat or prevent LBP were included. We calculated standardized mean differences (SMDs) and 95% confidence intervals (CIs). Certainty of evidence was evaluated with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. No trials assessed LBP prevention or addressed acute LBP. Nineteen trials (2362 participants) assessed treatment of chronic/recurrent LBP. Low-certainty evidence suggests that walking/running was less effective than alternate interventions in reducing pain in the short term (8 trials; SMD, 0.81; 95% CI: 0.28, 1.34) and medium term (5 trials; SMD, 0.80; 95% CI: 0.10, 1.49). High-certainty evidence suggests that walking/running was less effective than alternate interventions at reducing disability in the short term (8 trials; SMD, 0.22; 95% CI: 0.06, 0.38) and medium term (4 trials; SMD, 0.28; 95% CI: 0.05, 0.51). There was high-certainty evidence of a small effect in favor of walking/running compared to minimal/no intervention for reducing pain in the short term (10 trials; SMD, -0.23; 95% CI: -0.35, -0.10) and medium term (6 trials; SMD, -0.26; 95% CI: -0.40, -0.13) and disability in the short term (7 trials; SMD, -0.19; 95% CI: -0.33, -0.06). Scarcity of trials meant few conclusions could be drawn regarding cycling and swimming. Although less effective than alternate interventions, walking/running was slightly more effective than minimal/no intervention for treating chronic/recurrent LBP. <i>J Orthop Sports Phys Ther 2022;52(2):85-99.
