Objective: Hemophilia is an uncommon disorder that is difficult to diagnose and manage. Effective movement and individual physiotherapy interventions can improve physical activity levels, quality of life, and participation in children with hemophilia. This study aimed to investi- gate the effects of individually planned exercise on joint health, functional level, pain, partici- pation, and quality of life in children with hemophilia. Materials and Methods: Twenty-nine children with hemophilia (aged 8-18 years) were random- ized into either an exercise group with physiotherapists (n = 14) or a counseling home-exercise group (n = 15). Pain, range of motion, and strength were measured using a visual analog scale, goniometer, and digital dynamometer, respectively. Joint health, functional capacity, partici- pation, quality of life, and physical activity were assessed using the Hemophilia Joint Health Status, 6-Minute Walk Test, Canadian Occupation Performance Measure, Pediatrics Quality of Life, and International Physical Activity Questionnaire, respectively. The exercises were planned individually according to the needs of both groups. Additionally, the exercise group performed the exercise with a physiotherapist. Interventions were performed 3 days/week for 8 weeks. Results: The Hemophilia Joint Health Status, 6-Minute Walk Test, Canadian Occupation Performance Measure, International Physical Activity Questionnaire, muscle strength, and range of motion (elbow, knee, and ankle) were significantly improved in both groups (P < .05). Compared with the counseling home-exercise program group, the exercise group had better results in the 6-Minute Walk Test, muscle strength, and range of motion (knee and ankle flexion) (P < .05). No significant difference was found in pain and Pediatrics Quality of Life scores in both groups. Conclusion: Using individually planned exercise in children with hemophilia is an effective physiotherapy approach to improve physical activity, participation, functional level, and joint health.
