We observed an increased blood flow but an unchanged vasoconstrictor response in the affected hand in stage 1 of the disorder, but in stage 2 there was a decreased blood flow and a stronger vasoconstriction following an inspiratory gasp. These results suggest that in RSD patients the sympathetic nervous system function is altered and is different in the various stages.
