Nerve conduction studies for Carpal Tunnel Syndrome and Ulnar nerve entrapment

What is a Nerve Conduction Study?

A nerve conduction study is a test on the nerves in the arms and hands.  It is a test that measures how quickly messages are travelling along your nerves.  The speed at which the nerves are working can give information about whether a nerve is trapped or damaged. 

How is it performed?

The studies are performed by passing small electrical currents through the skin and making recordings of the natural electrical signals further down the nerve or over a muscle.  The electrical signals produce a pulsing, tingling sensation, which can be uncomfortable but should not be painful.  Some of the pulses will make your muscle briefly twitch. These tests take around 45 minutes.  There are no after effects and you will be able to go home or to work/school following the test.   

How do I prepare for the test?

Please inform the department prior to your appointment if you have a pacemaker.

Do not use hand lotions or creams.   

Your hands need to be warm for the test, however you will be offered a hand warmer upon arrival in the department.

Wear loose fitting clothing that can be rolled up to the upper arm.

Bracelets, rings and watches will have to be removed for tests on the hands.  If you are unable to remove a ring please do not have it cut off, we will be able to work around it.

If you are taking medication please continue to take it and bring a list of your medication with you.

Continue to eat meals as normal.

There are no side effects from the test.

How long will I have to wait?

You have been given a specific appointment time and patients are usually seen on time.  It is important that you arrive on time.  Please allow plenty of time for parking.

When will I get the results?

The results are sent to the doctor that referred you for the test and are usually available within seven days.

If you have any concerns or questions please speak to a Clinical Physiologist on the number below.
