Self-myofascial Release in Hemophilic Ankle Arthropathy

Study Overview
=================
Brief Summary
-----------------
Introduction: Hemophilic ankle arthropathy is manifested by degenerative functional alterations (deficit of muscle 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. Aimed: To evaluate the safety and effectiveness of a protocol by self-myofascial release with Foam Roller applied in patients with hemophilic ankle arthropathy. Patients: 70 patients with ankle arthropathy will be recruited for inclusion in the study. Patients will be recruited in 5 centers, from different regions of Spain. Intervention: Each session will last approximately 15 minutes, with five physiotherapy sessions per week for a period of 3 months. Patients will be evaluated at baseline, after the intervention, and after a follow-up period of 3 months. The treatment program includes 11 exercises that must be administered bilaterally. A mobile application will be developed where each patient will be able to observe the exercises to be carried out. Measuring instruments and study variables: digital goniometer (ankle range of motion); visual analog scale and pressure algometer (joint pain); Haemophilia Joint Health Score (joint status); dynamometer assess (muscle strength); 6-Minute Walking test (functionality of lower limbs); Mobile device (Activity record); Finger-floor test (muscle flexibility). 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, functionality and joint motion is expected.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Self-myofascial release<br>Each session will last approximately 15 minutes, with five physiotherapy sessions taking place over a period of 3 months. The Self-Myofascial release protocol for the lower limbs using a Foam Roller and and Solid Ball Massage, adapted to patients with hemophilic ankle arthropathy will include 11 exercises that must be administered bilaterally. A mobile application will be developed where each patient will be able to observe the exercises to be carried out. | Other: Self-myofascial release<br>* At home, the patients performed a daily session, lasting 15 minutes each, over 8 weeks. Patients accessed an ad hoc mobile application designed by the Hemophilia Physiotherapy research group (He-Foam®). This app, accessible from any smartphone, made it possible to watch the videos with all the exercises included in the intervention. The seven exercises under the specific protocol for patients with hemophilic arthropathy were: Self-release of the plantar region of the foot with a foam ball; Release of the posterior region of the leg with the foam roller; Release of the anterior leg region with a foam roller; Release of the hamstrings region with a foam roller; Release of adductor muscles with a foam ball; Release of abductor muscles with a foam roller; Release of pelvic trochanteric muscles with a foam roller<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline ankle bleeding after treatment and at 3 months | The safety of the intervention was evaluated through periodic monitoring of the development of ankle hemarthrosis. The physiotherapist in charge of evaluating the patients performed weekly follow-up telephone calls during the experimental phase to evaluate the development of ankle hemarthrosis or other complications (bruising). Bleeding-related data were collected by the evaluator after the follow-up period. | Screening visit, within the first seven days after treatment and after three months follow-up visit | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline ankle pain after treatment and at 3 months | The intensity of joint pain was assessed using the visual analog scale (VAS). This scale rates ankle joint pain with scores from zero to 10 points (from no pain to the maximum perceived pain). | Screening visit, within the first seven days after treatment and after three months follow-up visit | 
| Change from baseline range of ankle motion after treatment and at 3 months | The range of ankle motion in dorsal and plantar flexion was measured with a universal goniometer, with one-degree increments. The patient was placed in a supine position, with the axis of the goniometer on the lateral malleolus and the fixed arm of the goniometer parallel to the fibula. This procedure was accompanied by verbal stimulus to the patient to control the compensatory movement of the toes and the range of movement of the talocrural joint. The unit of measurement is the degrees (the higher the mark, the better the range of motion). | Screening visit, within the first seven days after treatment and after three months follow-up visit | 
| Change from baseline functional capacity after treatment and at 3 months | Functional capacity was measured with the 6-Minute Walk test, using the standardization described by the American Thoracic Society. The test was performed on a flat, hard, straight, 20-m long surface. Before the test, the evaluator instructed each patient to walk the track twice to familiarize themselves with the test and warm up. The evaluating physiotherapist used standardized verbal stimuli during the test with all subjects. Patients were asked to walk at a constant speed, without jumping or running, for 6 minutes. To measure the exact distance walked during the test the physiotherapist closely followed the patients with a stopwatch. | Screening visit, within the first seven days after treatment and after three months follow-up visit |
