Figure 2.

Some but not all patients with the expected changes, such as loss in nonpainful stimuli, gain in painful stimuli. Quantitative sensory testing profiles from ipsilateral and contralateral hands of CRPS patients and healthy controls. HC (healthy controls) n = 13, IL (ipsilateral) n = 20, CL (contralateral) n = 20. Black lines represent medians. Kruskal–Wallis test with Dunn test for multiple comparisons was used; *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001. CDT, cold detection threshold; CPT, cold pain threshold; CRPS, complex regional pain syndrome; HPT, heat pain threshold; MDT, mechanical detection threshold; MPS, mechanical pain sensitivity; MPT, mechanical pain threshold; PPT, pressure pain threshold; TSL, thermal sensory limen; VDT, vibration detection threshold; WDT, warm detection threshold; WUR, windup ratio.
