Neoprene knee sleeves aid in proprioception, the awareness of body position, by stimulating muscle fibers around the knee joint when worn. This helps prevent injury by tightening muscles and reducing stress on the joint. Knee sleeves can improve balance and decrease pain for those with osteoarthritis or anterior cruciate ligament injuries by enhancing thermal compression and proprioceptive feedback. Clinical studies show people wear knee sleeves have better balance control and lower scores on tests of loss of balance.
