Electromyography (EMG) is an electrical recording of muscle activity that aids in the diagnosis of neuromuscular disease. Muscles are stimulated by signals from nerve cells called motor neurons. This stimulation causes electrical activity in the muscle, which in turn causes contraction. This electrical activity is detected by a needle electrode inserted into the muscle and connected to a recording device. Together, the electrode and recorder are called an electromyography machine.
Emg (electromyography) is a test of your muscles and nerves. It is typically performed along with nerve conduction studies (ncs). The EMG portion involves placing a recording pin (like a fine wire antenna) into various muscles, looking for 'muscle distress signals' that could suggest nerve or muscle diseases/problems.ee below: Ncv, or nerve conduction velocity, is an electrical diagnostic test that provides information about abnormal conditions in the nerves. Emg, or electromyography is a technique for evaluating and recording the electrical activity produced by muscles. ...Read more.
