Muscles are controlled by nerves and it is possible to tell if there is an injury to a nerve by evaluating how the muscles it supplies and leg muscles can be tested to evaluate an injury in the back. Your physician interprets the results by making measurements of the responses and correlating them to your symptoms.Īn electromyogram (EMG) uses a fine wire electrode to evaluate the electrical activity of muscles. The electrodes are attached to a computer that analyzes the signals and produces a visual representation of them on its screen. The procedure involves stimulating the nerves with a small amount of electricity and recording how each nerve conducts this signal along its course.Įlectrodes in the form of stickers or wires record the responses of these stimulations. Nerve conduction studies (NCS) are performed to determine how well your nerves conduct signals.
