Lab-QST in patients. (A) Displayed are the frequencies (%) of abnormal values as compared to normative DFNS data. Patients showed more frequent thermal (CDT, WDT, and TSL) and mechanical (MDT) hypoesthesia as well as increased VDTs and decreased sensitivity to heat (HPT) and pinprick stimuli (MPS) as well as more frequent dynamic mechanical allodynia and paradoxical heat sensations. Furthermore, an increased sensitivity to pinprick stimuli (MPS) as well as paradoxical heat sensations were more frequent. (B) Displayed is the somatosensory profile of 73 patients. The dotted gray line represents ±1.96 SDs from the mean of corresponding normative values of the age-, sex- and location-matched DFNS database. All z-values <1.96 represent a loss of function, all z-values >1.96 indicate a gain of function. CDT, cold detection threshold; CPT, cold pain threshold; DMA, dynamic mechanical allodynia; HPT, heat pain threshold; lab-QST, laboratory quantitative sensory testing; MDT, mechanical detection threshold; MPT, mechanical pain threshold; MPS, mechanical pain sensitivity; PHS, paradoxical heat sensation; PPT, pain pressure threshold; TSL, thermal sensory limen; VDT, vibration detection threshold; WUR, wind-up ratio; WDT, warm detection threshold.
