Electrical stimulation is a technique that aims to stimulate the muscles using an electrical current in order to achieve a specific result. Electrical Muscle Stimulation (EMS) involves delivering small, low-voltage electrical impulses to a muscle via electrodes placed on the skin, thereby causing the muscle to contract. This muscle contraction can have two, very different benefits: first, it relieves inflammation, and second, it strengthens the muscle without involving the nervous system, which avoids pain and fatigue.
