Electrotherapy Tens & EMS
What is the difference between TENS and EMS?
All Electronic Muscle Stimulators are technically TENS (Transcutaneous Electrical Nerve Stimulators), the main difference being which nerves are stimulated by the device. EMS machines stimulate the muscle motor nerves, while TENS devices are designed to stimulate sensory nerve endings. They all work by generating an electrical pulse which stimulates motor nerves through the skin causing the muscles, supplied by those nerves, to contract.
