About

Background. The main physical sequela of patients with hemophilia is the development of a progressive, degenerative intra-articular lesion, known as hemophilic arthropathy). This sequela is manifested by chronic pain, limited range of motion, axial abnormalities, and periarticular muscle atrophy.

Objective. To assess the safety and effectiveness of an intervention through blood flow restriction, regarding the frequency of bleeding and the improvement in the perception of muscle activation and strength, functionality, joint pain, joint status and the perception of quality of life in patients with hemophilic arthropathy. knee and ankle.

Study design. Randomized, multicenter, single-blind clinical study. Method. 20patients with hemophilia A and B will be recruited in this study. Patients will be recruited in 3 regions of Spain. The dependent variables will be: bleeding frequency (self-registration), pain (measured with the visual analog scale), joint status (Hemophilia Joint Health Score scale), strength (dynamometer) and range of motion (goniometer). Three evaluations will be carried out: pre-treatment, post-treatment and after a follow-up period of 4 weeks.

Expected results. Observe the safety of blood flow restriction in hemophilia patients. To analyze the efficacy of blood flow restriction in improving muscle strength, joint pain, range of motion, and joint damage in patients with hemophilic knee and ankle arthropathy.

Masking: Single Blind

---

23 participants in 2 patient groups

Blood flow restriction group

Experimental group

Description:

The intervention will last 4 weeks, with a periodicity of 3 weekly sessions (34). In total there will be 12 sessions lasting between 15 and 30 minutes. The exercises will be: squats, knee extension and heel elevation (performing 4 sets of 15 repetitions with 30 seconds of rest between sets).

Treatment:

Other: Blood flow restriction

Control group

No Intervention group

Description:

The patients included in the control group will not receive any Physiotherapy intervention and will continue with their usual routine, being evaluated in the same periods as the rest of the patients.
