An EMG uses tiny devices called electrodes to translate these signals into graphs, sounds or numerical values that are then interpreted by a specialist.ĭuring a needle EMG, a needle electrode inserted directly into a muscle records the electrical activity in that muscle.Ī nerve conduction study, another part of an EMG, uses electrode stickers applied to the skin (surface electrodes) to measure the speed and strength of signals traveling between two or more points. ![]() Motor neurons transmit electrical signals that cause muscles to contract. Electromyography (EMG) is a safe and relatively painless test to discover whether your nerves are functioning properly. ![]() EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission.
