EMG (electromyography)

Electromyography, often abbreviated as EMG, is a diagnostic procedure used to assess the health of muscles and the nerve cells that control them. These nerve cells are called motor neurons, and they transmit signals that cause muscles to contract. An EMG translates these signals into graphs, sounds, or numerical values that a specialist interprets. During the procedure, small electrodes are placed on the skin or inserted through the skin into muscle tissue to record electrical activity produced by muscles.

EMG is commonly used to diagnose conditions that affect muscle tissue, nerves, or the junctions between them, such as muscular dystrophy, nerve dysfunction, or conditions like carpal tunnel syndrome. It's a valuable tool in determining the root cause of symptoms like muscle weakness, spasms, paralysis, and cramping.

Although it involves slight discomfort from the insertions and muscle contractions, EMG is generally a safe procedure. Its ability to provide precise and meaningful insights into muscle and nerve health makes it an essential part of diagnosing neuromuscular disorders.
