TENS (Transcutaneous Electrical Nerve Stimulation) is a non-invasive, low-frequency electrical current used to treat pain and muscle atrophy. A TENS device reduces pain by sending small electrical impulses through pads placed on the skin to underlying nerve fibres in the targeted area.
TENS works in two different ways;
1) Electrical stimulation of the nerve fibres modulates the way we process pain in that area. By blocking the pain signal from being carried to the brain, pain in that area is not perceived by the user.
2) TENS triggers the body to release endorphins, which are natural pain-killers.
EMS (Electronic Muscle Stimulation) triggers the contraction and relaxation of muscles using electric impulses. The impulses are generated by a device and delivered through electrodes (pads) on the skin in direct contact to the muscles to be stimulated. The impulses mimic the action potential coming from the central nervous system, causing the muscles to contract. EMS can be used for toning, reshaping, and for rehabilitation purposes, such as muscle atrophy.
