Abstract

Patients with reflex sympathetic dystrophy (RSD) affecting one limb show similar sympathetic traffic in nerves supplying the affected and unaffected limb, despite unilateral autonomic effector dysfunction. This argues against the notion that RSD is mediated by a reflex change in the pattern of sympathetic discharge and underlines the fact that autonomic effector disturbances give little information about underlying nerve traffic.
