Thresholds for cold detection (CDT), warmth detection (WDT), and heat pain detection (HPDT) obtained at different locations in each patient. An asterisk shows that the threshold was pathological compared to healthy controls. Classification of normal C-fibers obtained in microneurography as described in the methods. Abnormal units with either varying degrees of desensitization (Cxi + Cdes) or sensitized or spontaneously active afferent fibers (Csp + Csens) are shown in italics.
