Abstract Introduction Recurrent joint bleeds in haemophilia patients often cause musculoskeletal changes leading to functional capacity impairment. Aim In this study, we assessed the effects of aquatic activities performed to improve functional capacity in these patients. Methods The interventional protocol consisted of 24 hydrotherapy sessions during three months, in comparison with 24 swimming sessions. The pre‐ and post‐intervention assessment consisted of Functional Independence Score, haemophilia joint health score (HJHS), Pediatric Haemophilia Activities List (PedHAL), surface electromyography (SEMG) of thigh muscles to assess muscle electric activity, and load cell on extensor and flexor thigh muscles to evaluate muscular strength. Results Forty‐seven haemophilia patients were enrolled in this study, and 32 (23 severe haemophilia A, one moderate haemophilia A and 8 severe haemophilia B), median age 12y (6 to 40y), concluded the aquatic intervention. We observed a statistically significant increase with substantial improvement in functional capacity in the pre‐ and post‐intervention evaluation of hydrotherapy in comparison with the swimming protocol, with HJHS ( p = .006 and p = .001 respectively), PedHAL (Sum score) ( p = .022 and p = .001) and score FISH ( p = .021). The swimming group revealed significant improvements in muscular strength, in all muscles tested ( p = .005 and p = .001). SEMG signal amplitude reached significantly higher levels in all muscles evaluated after both interventions except for the vastus medialis (right) in the hydrotherapy group. Conclusion Our results concluded that both swimming and hydrotherapy were associated with physical improvement in haemophilia patients; however, only hydrotherapy lead to a more significant improvement in functional capacity.
