Table 1. Baseline Laser Doppler Flowmetry Values of Hands of CRPS Patients and Controls

Baseline laser Doppler flowmetry values of affected CRPS hands, contralateral clinically unaffected hands, and healthy (control) hands presented as median values and interquartile ranges. Rest flow and peak flow are measured with hands at heart level. The vasoconstriction index expresses the heart level to dependency ratio of the rest flow.

*P < 0.05 versus  controls.

CRPS = complex regional pain syndrome; PU = perfusion units.
