Figure 4.

Frequency of abnormal sensory findings per group. Patient data outside the 95% CI of healthy subjects were considered abnormal. Values below zero indicate significant loss of sensory function (ie, hypaesthesia); values above zero indicate significant gain of sensory function (ie, hyperalgesia). CDT, cold detection threshold; CI, confidence interval; CPT, cold pain threshold; DMA, dynamical mechanical allodynia; HPT, heat pain threshold; MDT, mechanical detection threshold; MPS, mechanical pain sensitivity; MPT, mechanical pain threshold; PHS, paradoxical heat sensation; PPT, pressure pain threshold; QST, quantitative sensory testing; TSL, thermal sensory limen; VDT, vibration detection threshold; WDT, warm detection threshold; WUR, wind-up ratio.
