Self-myofascial Release With Foam Roller in Patients With Hemophilic Knee Arthropathy

Introduction: Hemophilic ankle arthropathy is manifested by degenerative functional alterations (deficit of muscular strength, mobility and proprioception) (intra-articular alterations) and chronic pain. Myofascial release techniques are used to treat soft tissue adhesions, relieve pain, and reduce tissue sensitivity. Design. A randomized clinical trial. Directed: To evaluate the safety and effectiveness of a myofascial self-release protocol with Foam Roller applied in patients with hemophilic knee arthropathy. Patients: 58 patients with knee arthropathy will be recruited for inclusion in the study. The patients will be recruited in 5 centers, from different regions of Spain. Intervention: Each session will last approximately 15 minutes, with five physical therapy sessions per week over a period of 8 weeks. Patients will be evaluated at the beginning of the study, after the intervention and after a follow-up period of 2 months. The treatment program includes 11 exercises to be administered bilaterally. A mobile application will be developed where each patient can observe the exercises to be performed. Measurement instruments and study variables: digital goniometer (ankle range of motion); visual analog scale and pressure algometer (joint pain); Hemophilia Joint Health Score (Joint Condition); dynamometer evaluation (muscle strength); 6-minute walk test (lower extremity functionality); Mobile device (activity log); Finger floor test (muscle flexibility). At the same time, the study will make it possible to determine the joint bleeding caused by the applied physiotherapy treatment. Expected results: demonstrate the safety of this physiotherapy technique in patients with hemophilia. Likewise, an improvement in ankle pain, function and joint movement is expected.
