Why is a nerve test being performed?
A nerve test is ordered to evaluate the health of your muscles and your nerves. It is a diagnostic exam and helps your provider better plan a treatment path for you. The exam takes anywhere between 30 and 60 minutes and can include the arms, legs or both. Please avoid applying any lotions or perfumes to the arms or legs being tested on the day of the exam.
There are two portions of the nerve test: a nerve conduction study (NCS) and electromyography (EMG).
What is an NCS?
NCS is the portion of the test that examines the health of your nerves. Small, sticky electrodes are placed on the arm or leg being tested, and a small electric shock is created using a probe.
What is an EMG?
An EMG is the portion of the test that examines the health of your muscles. A small, thin, sterile needle is used to examine specific muscles and look for any changes that signify muscle or nerve damage.
What should I expect following the exam?
Most people have no pain following this test. Occasionally, there can be some discomfort in the regions that were tested with the needle. This discomfort can be treated by placing an ice cube over the needle site for ten minutes after you get home from the exam.
When do I get my results?
Your physician will study your exam and create a comprehensive report following your test. You will have the opportunity to discuss your testing results at your follow-up visit and discuss which treatment options are best for you.
