electromyography
Diagnostic test measuring electrical activity in muscles to assess neuromuscular function.
Full Definition
Electromyography (EMG) is a diagnostic procedure that records the electrical activity produced by skeletal muscles. In neuromuscular medicine documentation, EMG findings are crucial for diagnosing conditions like myopathy, neuropathy, and neuromuscular junction disorders. The test involves inserting needle electrodes into muscles or placing surface electrodes on the skin to detect muscle electrical activity at rest and during contraction.
Usage
Usage note: Often abbreviated as EMG in clinical documentation.
In Context
- "The electromyography results showed spontaneous fibrillations consistent with denervation." — Clinical report
- "Patient requires electromyography to differentiate between myopathic and neurogenic weakness." — Referral letter
