Electric muscle stimulation is a therapeutic procedure that elicits muscle contraction by admitting electrical impulses into the muscle. It is beneficial in the rehabilitation of injuries by decreasing pain and muscle spasms. Electrodes are placed on the skin in close proximity to the muscle being treated. Impulses are generated by an electrical unit that transmits a therapeutic current through the electrodes and into the injured tissue. EMS can be used for pain reduction, activation of muscular tissue, increasing range of motion and circulation surrounding injured tissue.
