Introduction: Hemophilic ankle arthropathy is manifested by functional degenerative alterations, intra-articular alterations, and chronic pain. Manual therapy techniques are used in the treatment of hemophilic ankle arthropathy for the improvement of pain and mobility. Design. Double-blind randomized pilot trial. Aimed: To evaluate the ultrasound changes by means of Doppler imaging after manual therapy intervention. Patients: A total of 20 adult patients with hemophilic ankle arthropathy will be recruited. Intervention: Each manual therapy session will last approximately 50 minutes, with 1 session per week for a period of 3 weeks. The treatment program includes 10 techniques that will be administered bilaterally. Measuring instruments: Patients will be evaluated qualitatively with ultrasound (HEAD-US scale) and assessment with Doppler ultrasound. The clinical variables will be joint damage (Hemophilia Joint Health Score) and pain intensity (Visual Analogue Scale). Expected results: Check the safety of manual therapy in patients with hemophilia regarding subclinical bleeding. Assess changes related to joint inflammatory state with imaging techniques. Observe changes in pain intensity and joint damage.
