AbstractPrevious literature has suggested that reflex sympathetic dystrophy, also known as complex regional pain syndrome (CRPS) type 1, is a relatively common finding after a stroke. However, much of this data was obtained before patients routinely received early intensive inpatient rehabilitation. The purpose of this study is to reevaluate the incidence of CRPS type 1 following an acute first stroke. Subjects admitted to an acute rehabilitation setting for stroke with no other concomitant neurologic or orthopedic injuries between October 1, 1996, and May 31, 1997, were studied. At admission and once a week until discharge, subjects were evaluated for shoulder pain, decreased passive range of motion of the shoulder, wrist/hand pain, edema, and skin changes. If three of these five criteria were positive, the subjects underwent a triple-phase bone scan (TPBS). Bone scan findings consistent with CRPS type 1 were taken as confirming the diagnosis. Of 64 subjects, 13 underwent bone scans, with only one positive result. Thus our study revealed a 1.56 percent incidence of CRPS type 1 following a first stroke. This incidence is much lower than the historically accepted 12.5 percent. We speculate that this low figure is related to early comprehensive rehabilitation that included proper upper extremity positioning and early mobilization with sensory stimulation.
