Effect of Water Exercise Therapy on Lower Limb Function Rehabilitation in Hemiplegic Patients with the First Stroke.

Researchers in China followed 160 people in the first weeks after a stroke, dividing them into two groups. One group received standard therapy and drugs alone. The other group did the same but also spent time doing exercises in water.

After 8 weeks, the water exercise group showed noticeably better scores on tests of balance, walking ability, coordination, and everyday function like dressing or using the bathroom. The groups started out equally disabled, so the difference came from the added water work. The finding suggests that water-based movement may help people recover lower limb function after a first stroke, though the study was done in one hospital in China and longer-term effects remain unknown.

This study looked at whether exercising in water could help people recover movement and strength in their legs after a stroke. The researchers found that people who did water exercises alongside their regular therapy improved more over 8 weeks than those who did regular therapy alone.

The improvements showed up in how well people could walk, keep their balance, and do daily tasks like getting dressed or bathing. Water exercise appeared to help people regain coordination and control in their affected leg.

The study does not tell us whether these gains last beyond 8 weeks, or whether water exercise works equally well for everyone. It is one study from one hospital, so we cannot yet say this will work the same way for all people recovering from stroke.

This randomised controlled trial of 160 acute post-stroke patients compared hydrotherapy plus standard rehabilitation against standard rehabilitation alone. The groups were well-matched at baseline across all measured variables.

After 8 weeks, the hydrotherapy group showed statistically significant improvements in Fugl-Meyer scores, functional ambulation category scores, Berg Balance Scale scores, and modified Barthel index scores compared to controls. The effect sizes appear modest rather than transformative, with the hydrotherapy group's Fugl-Meyer score rising to 21.45 from baseline compared to 16.60 in controls.

The study did not report on NIHSS or MRS scores post-treatment, limiting our understanding of broader neurological recovery. The 8-week timeframe is relatively short, and we lack information about retention of gains or optimal timing and intensity of water-based protocols.
