Blood flow restriction rehabilitation or bfr is a new and different way to rehabilitate muscle injuries particularly those occurring in an arm or leg. However it has other uses too.
Blood flow restriction therapy bfrt is achieved through the application of external pressure over the extremities via a cuff while performing rehabilitation.
Blood flow restriction therapy. Blood flow restriction bfr training has been around since the 1970 s but didn t catch on in the sports world until around 2015. By applying the right amount of external pressure to an extremity it s possible to maintain arterial inflow while occluding venous outflow distal to the occlusion site. The applied pressure is sufficient to maintain arterial inflow while occluding venous outflow distal to the occlusion site.
Professional sports teams have used bfr for quite some time to help athletes recover from injuries. What is blood flow restriction training. 5 bfr is not a new concept.
Blood flow restriction therapy bfrt is an innovative training method for the development of muscle strength and hypertrophy in the athletic and clinical settings. Blood flow restriction bfr training is a technique that combines low intensity exercise with blood flow occlusion that produces similar results to high intensity training. Blood flow restriction bfr therapy involves restricting blood flow to a limb through the application of a specialized tourniquet system combined with low load lifting to elicit a heightened state of metabolic stress leading to statistically significant gains in strength and hypertrophy muscle growth.
Blood flow restriction therapy is most often used to help patients recover from sports injuries joint pain or surgery. Blood flow restriction training can be used for general strengthening especially in certain populations such as the elderly. Even though it has been around since the 1960s there has recently been a surge in bfr research that supports how this technique can improve patient outcomes.
Blood flow restriction training can help patients to make greater strength training gains while lifting lighter loads thereby reducing the overall stress placed on the limb. Blood flow restriction bfr has been shown to produce beneficial adaptations to skeletal muscle. This can deliver bigger gains than exercise alone.
Bfr training involves placing a pneumatic restriction cuff similar to a blood pressure cuff proximal to the target muscle. It has been used in the gym setting for some time but it is gaining popularity in clinical settings 2 3. These adaptations have been documented in the civilian and military populations.
Bfr therapy may provide patients a safe method to begin strength training at earlier stages of rehabilitation to allow fo. The technology is now available to patients at upmc centers for rehab services crs. The model has been around for decades.
Blood flow restriction bfr is a hot topic in physical therapy right now. Through the combination of venous occlusion and low load resistance training it induces muscle development through a number of proposed mechanisms including anaerobic metabolism cellular swelling and induction of type 2 muscle fibers.
