An EMG can be performed by inserting a needle electrode into a muscle to record the electrical activity in the targeted muscle. The EMG is often performed along with a nerve conduction study.
An EMG can be performed in several settings including a doctor’s office, clinic or in a hospital. Your muscles will need to relax during the EMG. You will sit in a reclining chair, or lie down on a bed or table. The following will take place:
- The area of the skin where the test will occur is cleaned.
- A needle electrode is inserted into the muscle.
The electrode activity is recorded with the muscle at rest and contracted. If a reading is needed for different areas of the muscle, the electrode may be moved several times. An EMG procedure typically takes 30 to 60 minutes.
