Blood Flow Restriction (BFR) is a treatment option to help build strength and muscle quickly. It can be used for someone recovering from an injury, pre or post-operative and for people in pain. Using the Delfi Personalized Tourniquet System (PTS) with a built-in monitor, BFR safely utilizes brief and intermittent occlusion of blood flow to the target area. With less blood to the target area, less oxygen is present. This allows people to exercise at significantly reduced loads while achieving gains in strength, power and muscle growth without excessive load on the joints and body during recovery.
