What are Evoked Potentials?
Department of Clinical Neurophysiology
Evoked potentials involve stimulating specific nerves within the body, and recording a response along the pathway to the brain. The responses are picked up using small discs attached to the skin using sticky paste.
The whole procedure is safe and non-invasive.
The duration of the test will vary, and depends on how many nerves need to be tested. This procedure typically lasts between 1 and 2 hours.
Please bring spectacles if worn.
It is advisable to wear loose fitting clothing as it may be necessary to access the shoulder, lower back, leg and foot areas.
