2. Bilateral abnormalities in neuropathic pain<br />
Fig 2-3: <strong>Quantitative</strong> <strong>Sensory</strong> <strong>Testing</strong> (<strong>QST</strong>) z-score abnormalities in % at the affected (left)<br />
and contralateral side (right) in 81 neuropathic pain patients. <strong>QST</strong> parameter are ordered as sensory<br />
parameters: Cold Detection Threshold (CDT), Warm Detection Threshold (WDT), Thermal <strong>Sensory</strong><br />
Limen (TSL), Mechanical Detection Threshold (MDT), Vibration Disappearance Threshold (VDT),<br />
Paradoxical Heat Sensation (PHS), Dynamic Mechanical Allodynia (DMA) and nociceptive<br />
parameters: Cold Pain Threshold (CPT), Heat Pain Threshold (HPT), Pressure Pain Threshold (PPT),<br />
Mechanical Pain Threshold (MPT), Mechanical Pain Sensitivity (MPS) and Wind Up Ratio (WUR).<br />
Z-scores with positive sensory signs (gain of sensory function) plotted rightwards and negative<br />
sensory signs (loss of sensory function) plotted leftwards. Absence of DMA is normal and therefore<br />
no negative sign possible.
