E.M.S. stands for (Electrical Muscle Stimulation) which are predominately used to prevent, or reduce, muscle atrophy. Atrophy is the weakening and loss of muscle tone, which is usually experienced after surgeries or injuries. EMS has been proven to be an effective means of preventing muscle atrophy. EMS also helps by increasing blood flow to muscles, increasing range of motion, increasing muscle strength, as well as enhancing muscle endurance. Muscle Stimulators have pain management attributes in helping muscle related pain, such as a spastic muscle, sore muscles, or tight muscles.
