electromyography
Electromyography (EMG) is a diagnostic technique used to assess the electrical activity of muscles. It involves placing small electrodes on the skin or inserting fine needles into the muscle to record electrical signals during muscle contraction and relaxation. This information helps doctors evaluate muscle function and diagnose conditions affecting the nervous system or muscles.
EMG is commonly used to identify disorders such as muscle dystrophy, nerve damage, and carpal tunnel syndrome. The results can guide treatment options and rehabilitation strategies, making it a valuable tool in both clinical and research settings.
