The Correlation Between Central Conduction Time and Central Pain Syndrome in Chronic Neck Pain

July 7, 2026 updated by: Salah Eid Ahmed Ali, Cairo University
To investigate the neurophysiological relationship between Central Conduction Time measured via Somatosensory evoked potentials and pain intensity in individuals suffering from chronic neck pain

Conditions

Detailed Description

The explicit lack of direct studies linking Central conduction time to Central pain syndrome in Chronic neck pain, coupled with strong evidence for central sensitization as a key mechanism in CNP and the defining characteristic of CPS, points to a significant diagnostic gap. Somatosensory evoked potential serves as a valuable neurophysiological marker for the structural integrity and conduction velocity of central neural pathways, its direct relationship to the functional dysregulation seen in central pain syndrome in the context of chronic neck pain has not been explicitly established.
