Treatment of haemophilia patients with inhibitors against factor VIII/IX (FVIII/IX) is still challenging and recurrent haemarthroses cause arthropathy with associated restrictions on participation in physical activities and sports. Rehabilitation is a multidisciplinary approach which includes physiotherapy, occupational therapy, psychology, social work and technical applications like prostheses, orthoses (splints and braces), shoe adaptations, walking aids and adaptations in the house and work situation, but also education. The theoretical principles and practical advice regarding rehabilitation and physiotherapy for both children and adults with haemophilia without inhibitors are highly applicable for patients with inhibitors. Hydrotherapy is useful in the treatment of painful or stiff joints and/or muscles after an acute haemarthrosis, muscle bleeds and chronic arthropathy. In addition, it is of use in cases of chronic synovitis and to start mobilization after long periods of bed rest or during the weaning of a splint. In cases of bleeding and arthropathy, adequate treatment of pain is very important, as are functional exercises. Everyone should be physically active for 30-60 min day(-1). Participation in sports is recommended for people with haemophilia, the best sport being swimming. Children should participate in sports appropriate to their size and physical characteristics.
