About EMG & Nerve Conduction Study (NCS)
Nerve Conduction Studies (NCS) measure how quickly and strongly electrical signals travel along your nerves. Electromyography (EMG) records the electrical activity of muscles. Together they help locate and assess damage to nerves, nerve roots and muscles.
These tests are commonly used to evaluate tingling, numbness and weakness in the hands or feet.
Also known as: Nerve test, NCV, electromyography
Who is it recommended for?
Your doctor may recommend this if you have:
- Numbness, tingling or burning in hands or feet
- Peripheral neuropathy, including diabetic neuropathy
- Carpal tunnel syndrome
- Nerve injury or nerve root compression from the spine
- Muscle weakness or neuromuscular disorders
How is it done at AKG Hospital?
- NCS Small electrodes are placed on the skin and mild electrical pulses stimulate the nerves.
- EMG A fine needle electrode records activity in selected muscles at rest and during contraction.
- Analysis The neurologist interprets the results and correlates them with your symptoms.
How to prepare
- Bathe and avoid applying lotion or oil on the day
- Inform the doctor if you take blood thinners or have a pacemaker
- Wear loose clothing
Recovery & aftercare
You can return to normal activity right away. Mild soreness at needle sites may last a day.
Benefits
- Pinpoints the location of nerve damage
- Differentiates nerve from muscle disease
- Guides treatment and surgery decisions
Risks & when to seek help
The electrical pulses may feel like brief tingling taps. EMG needle testing may cause mild discomfort; serious complications are rare.
Frequently asked questions
Is the nerve conduction test painful?
The pulses cause brief tingling sensations. Most people tolerate it well.
