Physiotherapists aim to maximise quality of life and movement potential within the spheres of promotion, prevention, treatment/intervention and rehabilitation. Haemophilia care is witnessing a significant shift towards a new era of potentially life-changing treatments which offer a future of minimal or no bleeds for people with haemophilia. As such, physiotherapy intervention should be more proactive rather than reactive to treat and rehabilitate recurrent bleeding episodes. The role of the physiotherapist within the multidisciplinary team includes the differential diagnosis of musculoskeletal bleeding, supporting and encouraging higher levels of physical activity, rehabilitation to maximise physical potential and capabilities, assessment and treatment of non-bleed-related musculoskeletal issues, managing comorbidities and falls risk, and improving the longitudinal surveillance of musculoskeletal health. Encouraging and supporting people with haemophilia to become more active will improve wellbeing and improve health and health outcomes, and physical activity is becoming one of the most important outcomes for people with haemophilia. Recommendations on the best way to accurately capture these data are vital to ensure the full health benefits of new treatments for people with haemophilia are clear. [ABSTRACT FROM AUTHOR]
