Electronic Muscle Stimulation (EMS), or muscle stim, is a chiropractic therapy typically applied to a patient who has a lot of pain or spasm in the area of injury or complaint. When electrical muscle stimulation is performed, mild electrical current is applied to cause fast contraction to the muscles. Electrical muscle stimulation gives the patient a tingling sensation that is very soothing.
The fast contractions of the muscle experienced during this chiropractic therapy help to fatigue the muscle and allow it to relax, settling the spasm. The fast contraction also causes the body to release endorphins. The endorphins are the body’s natural pain killers, and so they help to reduce pain sensation to the area.
