An EMG will tell your healthcare provider how well Learn what an Electromyogram (EMG) test is, how it works, and what conditions it diagnoses. Find out about EMG procedures, costs, and results interpretation. An electromyograph detects the electric potential generated by muscle cells [3] when these cells are electrically or neurologically activated. It can help diagnose various conditions that affect the health of muscles and nerves, such as muscular dystrophy, carpal tunnel syndrome or amyotrophic lateral sclerosis. The presence, size, and shape of the wave form of the action potential produced on the oscilloscope, provides information about the ability of the muscle to respond to nervous What is electromyography? Electromyography (EMG) is a diagnostic test that helps detect neuromuscular abnormalities by measuring electrical activity in the muscles. Each muscle fiber that contracts will produce an action potential. Some types of electrical activity are normal, whereas some patterns of electrical activity suggest a disease of nerves or muscles.
