SmartCuffs 4.0 represent the 4th generation of the world’s most trusted blood flow restriction (BFR) system. Designed for both clinical and at-home use, these intelligent cuffs use AI-powered limb occlusion pressure (LOP) calibration to determine personalized pressure in as little as 10 seconds. The patent-pending iBFR technology removes guesswork by automatically adjusting pressure based on individual limb structure. With three proven BFR modes and built-in safety limits, SmartCuffs 4.0 deliver effective, comfortable, and controlled BFR training for rehabilitation, recovery, or performance.
