According to Federal Regulations set out by the FDA, electrical muscle stimulator (EMS) treatment is indicated for the following conditions:
Limited ROM-
In conditions where the reduction of physiological range of motion is due to or the result of fractures with consequent immobilization, operative intervention, or arthroscopy, in shoulders, knees, and backs.
Muscle Disuse Atrophy-
Muscle disuse atrophy is a reduction in muscle contraction and size due to a prolonged impairment or joint immobility from surgery, injury, or disease. The use of electrical stimulation to contract the muscle builds and strengthens the muscles, assisting in the prevention of disuse atrophy.
Muscle Spasms-
Muscle spasms and cramping often occur in areas of localized pain and tenderness. Stimulation is used to fatigue the “spastic” muscle.
Muscle Re-education-
Evidence has shown that a combination of both exercise and electrical stimulation is far superior in strengthening atrophied muscles.
Localizes Swelling-
Rhythmic muscle contraction helps improve blood circulation, thereby aiding in the reduction of localized swelling and tenderness.
Venous Thrombosis-
Immediate post-surgical stimulation of calf muscles to prevent venous thrombosis: The use of EMS to increase blood circulation assists in the prevention of venous thrombosis.
