Blood Flow Restriction (BFR) therapy is an advanced rehabilitation and strength training technique that involves applying a specialized cuff or tourniquet to partially restrict blood flow to a limb during low-intensity exercise. This controlled restriction reduces oxygen supply to the muscles, creating an environment that mimics high-intensity training and promotes muscle growth, strength, and endurance with significantly lower loads. BFR is particularly beneficial for individuals recovering from injuries, surgeries, or conditions that limit their ability to lift heavy weights, such as post-operative ACL reconstruction or joint pain. By stimulating muscle hypertrophy and enhancing metabolic stress, BFR accelerates recovery while minimizing joint strain. When performed under the supervision of trained professionals, BFR is a safe and effective method for improving strength and function, making it a valuable tool in physical therapy and sports rehabilitation.
