Evoked Potential Tests

​Evoked potential tests (SEP, VEP, BAEP)

In an evoked potential test, the function of the central nervous system’s nerve pathways are measured by giving the patient sensory, visual or auditory stimuli.

Responses caused by the stimuli are measured with sensors that are attached to the surface of the skin in the head area and, in a somatosensory evoked potential test, also in the area of the extremities, shoulders and neck.

Motor evoked potential test (MEP)

In a motor evoked potential test, the function of motor nerve pathways is measured by giving stimuli pulses with a magnet coil and by measuring the created responses in the area of the extremities with sensors attached to the surface of the skin.
