Formally known as blood flow restriction (BRF) training, the technique could be a revolutionary shift in rehabilitation. A pneumatic surgical tourniquet — similar to a blood pressure cuff — is applied to the injured limb to partially restrict blood flow while the patient engages in light weight strength training through full available range of motion. Unlike traditional strength training methods that require high loads to make appreciable gains, this form of training is performed at very low resistance. Research has shown rapid improvements in both muscle girth and strength in as little as a few weeks. This developing treatment technique is extremely promising in expediting the recovery of muscular strength following injury.
