Somatosensory Evoked Potential (SSEP) is an advanced neurophysiological test used to evaluate the integrity of sensory pathways that carry signals from the limbs to the spinal cord and up to the brain. During the test, small, controlled electrical stimuli are applied to nerves in the wrist, ankle, or other areas. Surface electrodes placed along the spine and scalp then record how quickly and effectively these signals travel through the nervous system. By analyzing the timing and strength of these responses, doctors can determine whether the sensory pathways are functioning normally or if there is a delay or block in conduction. SSEP is widely used in diagnosing spinal cord injuries, multiple sclerosis, nerve root compression, peripheral neuropathies, and other conditions affecting sensory pathways. It is also valuable during surgeries such as spine operations, where continuous monitoring helps prevent nerve damage. The test is non-invasive, safe, and highly sensitive, making it an essential tool for detecting subtle abnormalities that may not be visible on MRI or CT scans.
