Introduction: Hemophilic ankle arthropathy is manifested by degenerative functional alterations (deficit of muscle strength, mobility and proprioception), intra-articular alterations and chronic pain. Manual therapy techniques are used to treat soft tissue adhesions, relieve pain and reduce tissue sensitivity. Design. randomized pilot trial. Aimed: To evaluate the safety and effectiveness of a protocol by manual therapy techniques in patients with hemophilic ankle arthropathy. Patients: 24 patients with ankle arthropathy will be recruited for inclusion in the study. Patients will be recruited in seven centers, from different regions of Spain. Intervention: Each session will last approximately 50-60 minutes, with 1 physiotherapy session per week for a period of 3 weeks. Patients will be evaluated at baseline, after the intervention, and after a follow-up period of 3 weeks. The treatment program includes 10 exercises that must be administered bilaterally. Measuring instruments and study variables: Visual Analog Scale and pressure algometer (joint pain); Leg motion (ankle range of motion); and Haemophilia Joint Health Score (joint health). At the same time, the study will allow to determine joint bleeding caused by applied physiotherapy treatment. Expected results: To demonstrate the safety of this Physiotherapy technique in patients with hemophilia. Likewise, an improvement in ankle pain, joint motion, joint health and pressure pain threshold.
