From: Contact heat evoked potentials and habituation measured interictally in migraineurs
QST sensory profile of the volar forearm, right and left cheek of patients with migraine. The z-values were calculated based on the age-matched healthy control group (represented by the zero line). Data are shown as group means. CDT, cold detection threshold; WDT, warm detection threshold; CPT, cold pain threshold; HPT, heat pain threshold; MDT, mechanical detection threshold; MPT, mechanical pain threshold; WUR, wind-up ratio.
