NervesSomatosensory Evoked Potential (SSEP)
is a test which measures sensory electrical impulses which originate from the arms or legs and travel through the sensory spinal cord pathways up to the brain. The test takes place in a quiet room where you will be made comfortable and placed in a recumbent position. It is performed by placing electrodes over the skin and scalp. The electrical impulse is then measured to see how long it takes to travel through these spinal pathways. When the nerve pathway is abnormal, the signals recorded during the test will be slower than expected.
