A test that measures how well your nerves carry electrical signals.
A nerve conduction study (NCS) checks how well and how quickly the nerves in your arms and legs carry electrical signals. Small sensors are placed on the skin, and a mild electrical pulse stimulates the nerve.
It helps identify nerve damage or compression, such as carpal tunnel syndrome, and conditions affecting the nerves, including peripheral neuropathy. It is often done together with electromyography (EMG).
At Apollo Clinic Shyamnagar, the test is carried out by trained staff who explain each step, and the findings are discussed with you by the doctor.
| Aspect | Details |
|---|---|
| Duration | Usually 20–45 minutes, depending on how many nerves are tested |
| Preparation | Bathe beforehand and avoid lotions or oils on the skin; keep the limbs warm; tell the staff if you have a pacemaker or other implanted device; wear loose clothing |
| What Happens | Surface electrodes are placed on the skin over the nerve and muscle, a mild electrical pulse is delivered, and the response is recorded |
| Who It's For | People with numbness, tingling, burning or weakness in the hands, arms, legs or feet, and those with suspected nerve compression or neuropathy |
An NCS is recommended when a doctor needs to check whether nerve damage or compression is causing your symptoms.

Most people feel a brief tingling or mild tapping sensation with each pulse. It can be uncomfortable but is not usually painful.
The pulses are very mild and controlled. Tell the staff if you have a pacemaker or other implanted device before the test.
Nerve conduction velocity (NCV) is one of the measurements taken during a nerve conduction study. The study also records the strength of the nerve signal.
Yes. There is no recovery time, and you can carry on with your day.
