EMG
Electrical muscle test
EMG stands for electromyography, a diagnostic technique that measures electrical activity in muscles.
Electrodes detect signals when muscles contract, helping diagnose nerve and muscle disorders like carpal tunnel syndrome or muscular dystrophy.
The EMG showed nerve damage in her forearm.
In research contexts, EMG tracks muscle activation during movement or exercise.
