Muscle electrical stimulation is one of the ways of electrotherapy. It uses appropriate current to stimulate muscles. It can be used for the purpose of treatment by retracting muscle tissue, which can reduce pain and strengthen muscles. Force, delay or avoid muscle atrophy, reduce muscle spasm and increase skin blood circulation. In addition, for severe cases, such as part of the body, if the peripheral nerves of the affected part still have functions, the peripheral nerves can be stimulated to achieve muscle contraction and other functions; but if the peripheral nerve function has been impaired, the muscles can be directly stimulated to help muscle contraction. Prevent muscle atrophy and other purposes. For example, for patients in intensive care units, elderly people with little exercise or those who have postoperative orthopedics. The problem that traditional electrotherapy techniques encounter is that low-frequency currents can cause discomfort when entering the affected area through the skin.
