Effectiveness of an individualised swimming and education programme for chronic low back pain (EduSwim): a randomised controlled trial

This Australian RCT randomized 76 adults with chronic non-specific low back pain to either an individualized 8-week swimming program plus education (delivered via four telehealth physiotherapy sessions) or education alone (up to two sessions). At 8 weeks, the swimming group had significantly less disability on the Roland Morris Disability Questionnaire than the education-only group (mean difference -2.5 points, 95% CI -4.5 to -0.5), but this advantage shrank over time and was no longer statistically significant by 52 weeks; pain intensity showed only a small, possibly non-meaningful benefit, and the swimming group had more adverse events (56% vs 30%), almost all non-serious.

Why it mattersSwimming is widely recommended by clinicians for chronic low back pain despite almost no trial evidence, and this is the first RCT to test it directly as the primary intervention, giving learners a concrete example of how weak evidence can underlie common practice recommendations.

• ?The swimming group received four telehealth sessions versus up to two in the education-only arm, so the intervention was not attention-matched; how much of the short-term benefit might reflect extra clinician contact and health-coaching rather than swimming itself?
• ?Given that the benefit was present mainly at 8 weeks and largely dissipated by 26-52 weeks alongside declining swimming adherence, how would you counsel a patient about whether to start a swimming program and how to sustain it long term?
