Effects of breathing exercise and thoracic techniques on pain and disability in low back pain: A systematic review and meta-analysis

Breathing and thoracic manual techniques may be effective in reducing disability and, to a lesser extent, pain in patients with LBP, but the overall certainty of evidence is low. However, the quality of the evidence is low. Variability in treatment protocols, study quality, blinding, and outcome measures likely contributed to inconsistencies. Further high-quality trials with standardized protocols are needed to confirm these findings and inform clinical practice.
