Normative Values Laser Nociceptive Evoked Potentials Depending on the Age

Summary

Different neurological damage may alter the pain conduction systems centrally (spinothalamic pathway) or peripherally (small caliber sensory fibers A delta and C). The laser thermal stimulation selectively stimulates the pain pathways and generates nociceptive signals conveyed to the cortex. Registering these cortical responses constitute the technical laser nociceptive evoked potentials. If these tests are routinely used, their interpretation must remain cautious especially in the elderly.
