SYDNEY — The EduSwim clinical trial found that an eight-week individualized program of swimming and education was clinically effective in reducing disability from chronic low back pain. The study results were published in the British Journal of Sports Medicine on July 21, 2026.

The intervention group improved function and pain significantly more than the control group, which received education alone. After eight weeks, disability was significantly lower in the swimming group.

The study recruited 76 adults aged 26 to 74, with an average age of 41 years who experienced disability due to low back pain lasting for at least 12 weeks. Participants were allocated at random to one of two groups.

The intervention group received an eight-week individualized program of swimming and education, supported by four telehealth coaching sessions with a physiotherapist. The swimming program was based on each participant's current swimming ability and fitness, with a goal of achieving three sessions of 30-45 minutes by the end of the eight weeks.

Education covered key concepts including 'Pain does not always equal harm', 'The back is made for movement', 'Flare-ups are likely', and 'The best management is to keep moving'. The control group had one to two sessions with a physiotherapist to learn the same key messages about back pain as the intervention group but otherwise continued their usual treatment and activity.

"They weren't regular swimmers, but they were able to swim 25 metres and feel confident in the water," physiotherapist Deborah Wareham said. "They improved by about 50 per cent from where they were before starting the program."

"Compared to the control group who received education only, swimmers scored on average 2.5 points or 30 per cent lower on a widely used disability scale," Wareham said. "In fact, the improvement we saw in our study compares favourably with effects reported for other exercise such as Pilates in a recent meta-analysis."

The benefit of swimming persisted at follow-ups at 26 and 52 weeks, although the difference between the groups reduced over time. Secondary outcomes including pain intensity, functional limitation, pain self-efficacy, and fear of movement were lower in the swimming group early in the program, but the difference reduced over time.

"The argument for swimming in back pain is logical, but it was important to test this," said Professor Mark Hancock. "Swimming can improve range of motion, strength and general aerobic capacity and the buoyancy of water can help people engage with movements that might otherwise be painful or limited."

"Importantly, participants told us swimming built their confidence to start exercising and engage with other meaningful physical activities – some continued to swim after the program, while others transitioned to other forms of exercise," Hancock said. "Now we have the evidence to support the recommendation – swimming is a suitable exercise for people with back pain, and it helps."

Chronic low back pain affects a significant portion of the adult population, often leading to long-term disability and reduced quality of life. The EduSwim trial provides clinical evidence for a non-pharmacological intervention that leverages the unique properties of water to facilitate movement and reduce pain-related fear.

The persistence of benefits at 26 and 52 weeks suggests that swimming may offer a sustainable management strategy for chronic conditions. The study's publication in a leading sports medicine journal adds weight to recommendations for aquatic therapy as a viable component of comprehensive back pain treatment plans.
