Figure 2. QST z-score abnormalities for patients graded as ‘definite’ and ‘unlikely’ neuropathic pain.

Figure 2

Quantitative Sensory Testing (QST) z-score abnormalities in % for ‘definite’ neuropathic pain (top) and ‘unlikely’ neuropathic pain (bottom) grades. QST parameter are ordered as sensory parameters: Cold Detection Threshold (CDT), Warm Detection Threshold (WDT), Thermal Sensory Limen (TSL), Mechanical Detection Threshold (MDT), Vibration Disappearance Threshold (VDT), Paradoxical Heat Sensation (PHS), Dynamic Mechanical Allodynia (DMA) and nociceptive parameters: Cold Pain Threshold (CPT), Heat Pain Threshold (HPT), Pressure Pain Threshold (PPT), Mechanical Pain Threshold (MPT), Mechanical Pain Sensitivity (MPS) and Wind Up Ratio (WUR). Z-scores with positive sensory signs (gain of sensory function) plotted upwards and negative sensory signs (loss of sensory function) plotted downwards. Absence of DMA is normal and therefore no negative sign possible.
