What’s the preparation for the test?
Full instructions should be given to EEG patients when they schedule their test. Individuals on certain medications that affect the central nervous systems will be told to discontinue their prescription for a short time prior to the test. Patients should avoid food or beverages that contain caffeine, a central nervous system stimulant.
Patient preparation for nerve conduction testing is minimal. The extremity being examined should be free of perfume, lotion, and powder.
What types of procedures are available at MCHHS?
- Nerve Conduction testing
What happens during the exam?
A technician attaches approximately 16-20 electrodes to the patient’s scalp with a conductive, washable paste. The EEG electrodes are painless, and are used to measure the electrical activity in various regions of the brain.
In nerve conduction testing, the technician will place round metallic electrodes on the skin over the nerve at various locations of the body. The technician will send electric impulses through specific nerves, and the response time or reaction of the nerves will be measured. The response time of each individual nerve will help determine if the nerve is normal or abnormal.
Are there any risks?
No, there are no apparent risks involved.
