Electrical Muscle Stimulation, referred to as EMS, is an electronic device used to stimulate motor nerves by causing a muscle contraction. EMS is mostly used for preventing or reducing muscle atrophy. Atrophy is the weakening and loss of muscle tone, which is usually experienced after surgeries or injuries.
EMS has been perceived as a means of increasing blood flow to muscles, increasing range of motion, increase muscle strength, as well as enhance muscle endurance. EMS has pain management attributes in regards to muscle related pain, such as spastic muscle, sore muscles or tight muscles.
