needle electromyography

Needle electromyography (EMG) is a medical test that assesses the health of muscles and the nerve cells that control them. During the procedure, a thin needle electrode is inserted into a muscle to record electrical activity while you relax and then contract the muscle. This helps doctors diagnose conditions such as muscular disorders, nerve damage, or diseases affecting communication between nerves and muscles. The results provide valuable insights into muscle function and the underlying causes of symptoms like weakness or pain, guiding treatment decisions effectively.
