EMS Vs. Tens

Electronic Muscle Stimulators (EMS) and Transcutaneous Electrical Nerve Stimulators (TENS) both generate electrical impulses that stimulate the nervous system. They are used by the medical community to treat acute injuries and chronic pain.

  1. Function

    • Both EMS and TENS units have multiple electrodes that are placed on the outside of the skin and around the affected area.

    Features

    • EMS units stimulate muscle nerves and cause muscle fibers to contract. TENS units stimulate sensory nerves, temporarily alleviating pain.

    Benefits

    • TENS units are beneficial in reducing pain associated with chronic nerve-related pain. EMS units are used in acute injury situations, because they prevent muscle atrophy and increase blood flow to the affected area.

    Time Frame

    • Both EMS and TENS units can be used multiple times per day, but they should only be used for fifteen to twenty minutes at a time.

    Considerations

    • Although EMS and TENS units are safe, they should be used under the direction of a doctor or physical therapist. EMS electrodes should not be placed on the chest, and TENS should not be used during pregnancy or placed around the eyes, at the front and side of the neck or on open wounds.
