| Sumario: | Introduction. Hemophilic knee arthropathy leads to a reduction in muscle mass and strength. Blood flow restriction (BFR) involves the application of a compressive cuff that enables strength training with reduced loads. Objective. To evaluate safety as the primary outcome and the efficacy (muscle strength and activation, functional capacity, and quality of life) as secondary outcomes of a quadriceps strengthening programme using blood flow restriction in patients with haemophilia. Methods. A randomized clinical trial was conducted with 33 participants assigned to either an experimental group (strength training with BFR) or a control group. The four-week intervention included three weekly sessions and two strength exercises (leg extension and squat). Outcomes assessed were safety (clinical hemarthrosis), strength (dynamometry), muscle activation (surface electromyography), pain threshold (pressure algometry), range of motion (goniometry), functional capacity (Timed Up and Go), and quality of life (36-Item Short Form Survey). Follow-up assessments were performed four weeks post-intervention to evaluate effect persistence. Results. Thirty participants completed the study. No participants experienced clinical hemarthrosis or hematomas during the intervention, confirming safety as the primary outcome. Additionally, blood flow restriction training produced significant gains in quadriceps strength (p<0.001;η²p=0.19) and activation (p<0.001; η²p=0.28). Further improvements (p<0.05) were observed in pain threshold, knee range of motion, and the physical component of quality of life. Conclusions. Blood flow restriction strength training is safe for patients with hemophilia. It may enhance quadriceps strength and activation, raise pain thresholds, and improve knee mobility. Patients show better physical functioning, less bodily pain, and improved physical quality of life. |
