An electromyography (EMG) is conducted to measure muscle function. In most cases, a nerve conduction study (NCS) is conducted at the same time, and is most often done first.
Preparing for this procedure
Prepare for your test as instructed. Shower or bathe, but don't use powder, oil, or lotion. Your skin should be clean and free of excess oil. Wear loose clothes. But know that you may be asked to change into a hospital gown. The entire test will take about 60 minutes. Be sure to allow extra time to check in.
Additional instructions may be provided by your physician.

How this procedure is performed
The doctor will clean the area being tested with alcohol. A fine needle will be inserted into the muscles in this region. When the needle is inserted, you may feel as if your skin is being pinched.
This is repeated on other muscles. The needle allows the electrical activity in your muscles to be measured. No electrical currents are applied with the needle.
