About This Test
Electromyography (EMG) is a diagnostic procedure that measures the electrical activity of muscles to determine how well they function. When performed on the upper or lower limbs, it helps identify conditions affecting the nerves or muscles of the arms or legs. A fine needle electrode is inserted into specific muscles to record electrical signals at rest and during contraction. EMG is extremely useful for diagnosing problems like radiculopathy, peripheral neuropathy, carpal tunnel syndrome, sciatica, muscle dystrophy, and motor neuron diseases. It determines whether muscle weakness is due to nerve dysfunction or a primary muscle disorder. The test may cause mild discomfort due to needle insertion, but it provides valuable information about neuromuscular health. Doctors often pair EMG with NCV testing for a complete evaluation.

TAT Policy
The Turnaround Time (TAT) depends on the following factors:
- Registration date and time
- Type of scan or test
- Scan time or sample collection time
In uncommon circumstances, TAT may be delayed due to test complexity or reasons beyond our control. You will be informed of the estimated TAT at the time of registration.
