About this study

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.
