Yoga eases back pain, but no better than any other exercise

Chronic low back pain is one of the most common and disabling musculoskeletal conditions, and yoga has become a hugely popular response to it. Earlier work suggested yoga helps, but two arguments have never been settled: how long the benefit actually lasts, and whether yoga offers anything beyond what standard physiotherapy-style exercise already provides. This review set out to compare yoga against both non-exercise approaches, such as usual care and education, and against physical therapy exercise, tracking pain, disability and quality of life at multiple time points.

The authors searched PubMed, Web of Science, the Cochrane Central Register of Controlled Trials and Embase from inception to 1 November 2019 for randomised controlled trials of yoga in people with chronic low back pain. Eighteen trials were included. Studies were eligible if they assessed pain, back-specific disability or quality of life, methodological quality was judged with the Cochrane risk of bias tool, and outcomes were combined as mean differences or standardised mean differences depending on the scales used.

Compared with non-exercise, yoga significantly reduced pain at 4 to 8 weeks, at 3 months and at 6 to 7 months, but the difference was no longer significant at 12 months. Disability told a more durable story, with significant improvements at every point from 4 to 8 weeks through 12 months. Against physical therapy exercise, however, there was no significant difference on pain or disability. Neither physical nor mental quality of life improved significantly against any comparator, a null finding worth taking as seriously as the positives.

This confirms yoga's place as a genuinely useful option for chronic low back pain while deflating the idea that it is special. The pattern, with benefits over doing nothing but parity with other structured exercise, echoes a broader theme in back pain research: movement helps, and the particular flavour of movement matters less. The certainty of the evidence ranged from very low to moderate, and why pain relief faded by 12 months while disability gains persisted remains an open question.

If you live with chronic low back pain and enjoy yoga, this is solid support for continuing: it beat usual care and education on both pain and function. If you would rather do physiotherapy exercises, strength work or another structured programme, there is no evidence you are missing out, because yoga showed no advantage over other exercise. The honest framing is that the effective ingredient appears to be moving consistently, not any single discipline.
