A kind of machine used at medical facilities for treatment of pain by causing muscles to relax is the electric muscle stimulator (EMS) machine. Low voltage pulses are used by the device that stimulates the motor nerves to make the muscles contract. The electric stimulation from the EMS machine also strengthens the muscles and increases the circulation of the blood. Some people also use the devices for body building and fitness purposes.

The electric muscle stimulator machine offers many benefits especially to people who are in the first stages of physical rehabilitation after an injury has affected the brain, or has caused some muscles to be unused for a long period. The purposes of electric stimulation treatments include (1) building the basic muscle strength and tone, and (2) to make the muscles contract. This strengthens the cognitive tissue that links the muscle movement to the brain.

If you are suffering from a reduced motion in your back, knees, or shoulders due to operation or fractures, the electric stimulation therapy can help your muscles in these particular areas to function again. The muscles are then stimulated, and the amount of movement is either retained or enhanced. Most of the muscle stimulator machines that have FDA approval are intended for use in rehabilitation and physical therapies by all healthcare professionals.

When a muscle is wasted away, it means that it loses tone as a result of not being used for a long time. This condition is called muscle atrophy, and is characterized by a reduction in muscle mass, or by other medical conditions. Use of EMS machine can slow, if not totally prevent, the effects of muscle atrophy. The weakened muscles are kept active. Another condition is muscle spasm and cramping, and these can cause great pain to a person who suffers from it. The electric stimulation offered by the electric muscle stimulator machine can help the muscle to relax and get strengthened and be functional again as before.
The EMS machine also gives you the benefit of perfect blood circulation. After you have had a surgery, the device can prevent the coagulation of the blood in your blood vessel or your heart. The machine can help you avoid blood clot. When a patient is bedridden, or is confined to a wheelchair or any other equipment that can cause pressure to be constantly applied to some parts of the body, pressure sores do occur. But this can be reduced by using the EMS machine, according to some medical studies.

Another condition that can be treated by the EMS machine is osteoarthritis. This is a condition resulting from degradation of the tissues of the joints. Osteoarthritis is a very painful condition; sometimes it can be debilitating. In a case of hip osteoarthritis in an elderly patient who has just had ortho-plasty surgery, the electric muscle stimulator can be applied as an important part of the physical therapy. You can note that all these applications listed above are approved by the US Drug and Food Administration. The EMS application that has not yet been approved is the use of EMS for weight loss.
