OBJECTIVE: To quantify the dose-response relationship between overall and specific exercise modalities and pain, in patients with nonspecific chronic low back pain (LBP). DESIGN: Systematic review with Bayesian network meta-analysis. LITERATURE SEARCH: We searched the Medline, Embase, Web of Science, Cochrane Library, Scopus, and SPORTDiscus databases from inception to June 2023. STUDY SELECTION CRITERIA: We included randomized controlled trials of exercise interventions in adults with nonspecific chronic LBP and at least 1 pain outcome reported at the main trial end point. DATA SYNTHESIS: A random-effects network meta-analysis was conducted. We assessed risk of bias using the Cochrane Risk of Bias Tool 2.0, and used the GRADE approach to judge the certainty of evidence for each outcome. RESULTS: Eighty-two trials were included (n = 5033 participants). We found a nonlinear dose-response relationship between total exercise and pain in patients with nonspecific chronic LBP. The maximum significant response was observed at 920 MET minutes (standardized mean difference = -1.74; 95% credible intervals: -2.43, -1.04). The minimal clinically important difference for achieving meaningful pain improvement was 520 MET minutes per week. The dose to achieve minimal clinically important difference varied by type of exercise; Pilates was the most effective. The certainty of the evidence was very low to moderate for all outcomes. CONCLUSION: The dose-response relationship of different exercise modalities to improve pain in patients with nonspecific chronic LBP had a U-shaped trajectory and low- to moderate-certainty evidence. The clinical effect was most pronounced with Pilates exercise. J Orthop Sports Phys Ther 2024;54(5):1-13. Epub 8 March 2024. doi:10.2519/jospt.2024.12153.

There is growing evidence within the Pain Management literature that it is not exercise per se but activity reactivation that is important to regain function and be less bothered by pain. Persistent spinal pain is often due to catastrophizing, fear avoidance, unhelpful beliefs about pain, injury and recovery, altered mood, disrupted sleep, etc. Understanding the drivers behind their fears, beliefs and inactivity, and their preferred ways to reactivate then shapes their individual programme. There isn't one exercise type or modality that will suit everybody. Graded exposure to activity, with encouragement to experiment with movement, exercise of their choice, and activity is the best way to get clients to optimise their life and be less bothered by their pain.
