Overview of sensory abnormalities in QST.

Patient numbers with sensory abnormalities at the affected (Table 2A, top) and contralateral side (Table 2B, bottom). Sensory abnormalities were defined as Z score 1.96 corresponding with 95% of values obtained from healthy volunteers. Shown are direction (n of sensory gain/n of sensory loss) and overall abnormalities in percent (% of sensory abnormality) for each Quantitative Sensory Testing (QST) parameters in 81 chronic pain patients. QST parameter: Cold Pain Threshold (CPT), Heat Pain Threshold (HPT), Warm Detection Threshold (WDT), Wind Up Ratio (WUR), Cold Detection Threshold (CDT), Thermal Sensory Limen (TSL), Paradoxical Heat Sensation (PHS), Mechanical Pain Threshold (MPT), Mechanical Pain Sensitivity (MPS), Mechanical Detection Threshold (MDT), Vibration Disappearance Threshold (VDT), Pressure Pain Threshold (PPT) and Dynamic Mechanical Allodynia (DMA). Wilson estimates with upper and lower bound of the 95% CI for each QST parameter (* p
