Overview of sensory abnormalities at the contralateral side given an abnormality at the affected side.

Patient numbers with sensory abnormalities and in their direction (n of sensory gain/n of sensory loss). Sensory abnormalities were defined as Z score 1.96 corresponding with 95% of values obtained from healthy volunteers. Percent (% of sensory abnormality) indicates overall occurrence of sensory abnormalities for each Quantitative Sensory Testing (QST) parameter at the contralateral side once there was already an abnormality for the same parameter detected at the affected side in 81 chronic pain patients. QST parameters: 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
