electromyography needle

Electromyography (EMG) needle is a thin, hollow needle inserted through the skin into a muscle to measure its electrical activity. When muscles contract or are at rest, they generate small electrical signals. The EMG needle detects these signals and sends them to a machine for analysis. This test helps diagnose nerve or muscle disorders by showing how well muscles respond and how nerves communicate with them. It’s a common, minimally invasive procedure used by doctors to gather important information about muscle health and nerve function.
