![]() This promotes strengthening of both type I and type II muscle fibers and facilitates integration of motor performance into functional use. 141 NMES is most effective when used in conjunction with volitional muscle contractions. ![]() 141 It is proposed that this is why NMES can accelerate strengthening and shorten rehabilitation times. NMES recruits type II muscle fibers first because the axons of their motor units are larger and more superficial and offer lower resistance to electrical stimulation. ![]() 140 NMES preferentially strengthens type II muscle fibers because it recruits motor units with type II fibers before those with type I fibers, which is the opposite order from voluntary contractions where type I fibers are recruited first. 137-139įor NMES to increase muscle strength the electrical current must produce contractions that are at least 50% of the maximum volitional isometric contraction (MVIC) force for the targeted muscles. NMES has been shown to accelerate functional recovery after surgery, prevent disuse atrophy, reduce ROM deficits, and improve motor control in patients with strength deficits of various etiologies. NMES can help when the client is either unable or unwilling to volitionally elicit strong muscle contractions. Neuromuscular electrical stimulation (NMES) can be an effective component of a rehabilitation program for muscle weakness. ![]() Reiman, in Physical Rehabilitation, 2007 NEUROMUSCULAR ELECTRICAL STIMULATION ![]()
