What is Surface EMG (SEMG)

As muscles contract, electrical signals are created within the muscle that may be measured from the surface of the body. A procedure that measures muscle activity from the skin is referred to as surface electromyography (SEMG).

Researchers and clinicians use SEMG to evaluate the functional status of skeletal muscles and assist inneuromuscular training and rehabilitation. The small electrical current, or signal, which comes from active muscles, is detected by sensors placed on the skin directly above the muscles. The strength and pattern of the signal is displayed onto a computer screen and the data is collected in a software program that is able to run various analyses of the data to create useful reports regarding muscle function.
