EEG/EMG Appointment Instructions


EMG Appointment Instructions

• Please do not apply lotion.

• Wear loose fitting clothing.

Electromyography (EMG) measures muscle response or electrical activity in response to a nerve's stimulation of the muscle. The test is used to help detect neuromuscular abnormalities. During the test, probes are placed on the skin to detect nerve responses and a small needle is used to check the performance of the muscles. A nerve conduction test measures how well and how fast the nerves send electrical signals.


EEG Appointment Instructions

• No more than 5 hours of sleep the night before the test

• No caffeine for at least 12 hours prior to the test

• Your hair needs ot be clean and dry (The tech uses wax to attached

electrodes to your head so your hair may be messy afterward)

• You may eat and take any of your normal medications as usual


An electroencephalogram (EEG) is a test used to detect abnormalities related to

electrical activity of the brain. This procedure tracks and records brain wave

patterns. Small metal discs with thin wires (electrodes) are placed on the scalp,

and then send signals to a computer to record the results.
