Zusammenfassung

Perception of pricking pain and of non-painful cold stimuli plays an important role in quantitative sensory testing (QST) as parameters for A-delta-fiber function. Since QST depends on active participation of the patient, objective tests for A-delta-fiber function are also needed. Whereas laser-evoked potentials (LEP) have been validated as objective test to assess the pathways mediating pricking pain, no such test exists for the thermoreceptive pathways for cooling. This study used evoked potentials (EPs) recorded from 7 scalp electrodes elicited by a contact-thermode stimulator (CHEPS, Medoc Ltd.) and subjecti…
