Electrical muscle stimulation (EMS), also known as neuromuscular electrical stimulation (NMES) or Transcutaneous Electrical Nerve Stimulation (TENS) uses an electrical current to stimulate your muscles. 

Most people who have had neuromuscular electrical stimulation treatment find it relaxing and helpful. Electronic muscle stimulators can be used to stimulate muscle healing, reduce pain, tone, and strengthen your muscles.

It produces the impulses and delivers them through electrodes placed on the skin close to the muscles that need stimulation. The impulses are similar to the brain's impulses to stimulate muscle tissue. Stimulation results in the strengthening and toning of ulcers and chronic wounds.

Sports injury rehabilitation has become a popular use for EMS devices. The EMS machine generates an electrical current that stimulates muscles after a person sustains a muscle injury. This stimulation causes the tissue to be repaired.

Electronic Muscle Stimulation devices produce electrical signals that stimulate nerves. The electrodes are attached to the patient using adhesive-held connectors. The pads can be placed on a set of muscles and the EMS unit will send impulses to the EMS unit. The muscles will then contract and relax. These contractions will be similar to those that occur during regular exercise.

A practitioner can adjust the voltage to apply pressure to different areas depending on what area needs treatment. Low voltage stimulates and reduces muscle tissue pain. Regular exercise may not affect EMS devices. They stimulate injured muscle tissue, resulting in the repair, strengthening, and toning of the damaged tissue.
