Abstract

Objective: The purpose of this study was to determine the effect of unloaded movement facilitation exercises on outcomes for people with nonspecific chronic low back pain (NSCLBP).

Methods: This systematic review was conducted according to Cochrane Back Review Group and Quality of Reporting of Meta-analyses (QUORUM) guidelines. Exercise effects were reported as standardized mean difference (SMD) with 95% confidence intervals (95% CI).

Results: Six high-quality randomized controlled trials were included. For NSCLBP effects favored McKenzie therapy over intensive trunk strengthening for pain: SMD: short-term: 0.35 (0.10, 0.59); long-term 0.36 (0.12, 0.61) and short-term function: SMD: 0.45 (0.20, 0.70) and were comparable for medium-term function: SMD: 0.15 (-0.90, 0.40). Effects of favored McKenzie therapy were comparable to specific spinal stabilization exercises for short-term pain: SMD: 0.63 (-0.11, 1.38) and function: SMD: 0.47 (-0.27, 1.20). Pooled effects favored McKenzie therapy over other exercises for short-term pain (pooled SMD: 0.38 (0.14, 0.61)) and were comparable for short-term function: SMD: 0.10 (-0.20, 0.40). Yoga compared to trunk strengthening produced comparable effects for pain: (SMD: short-term: 0.13 (-0.46, 0.71); medium-term 0.51 (-0.08, 1.11)) and function SMD: short-term: 0.51 (-0.08, 1.10); medium-term 0.38 (-0.22, 0.97)). Compared to education, effects of yoga were large for medium-term pain and function (pooled SMDs: 0.92 (0.47, 1.37); 0.95 (0.50, 1.40)). Effects favored unloaded movement facilitation exercises of McKenzie compared to other or no exercise and were comparable for yoga.

Conclusions: For NSCLBP, there is strong evidence that unloaded movement facilitation exercise, compared to no exercise, improves pain and function. Compared to other types of exercise, including effort-intensive strengthening and time-intensive stabilization exercise, the effects are comparable. This challenges the role of strengthening for NSCLBP.
