Method
Retrospective chart review was performed in 561 patients. Among 561 stroke patients, 116 subjects were recruited and classified into two groups: patient group, 43 cases with RSD; control group, 73 cases without RSD. Upper extremity function was assessed based on feeding, dressing and personal hygiene scores of the modified Barthel index at the beginning of rehabilitation treatment and at the time of discharge. Causes of stroke and length of stay were recorded. Median nerve-somatosensory evoked

potential studies were performed and assessed.

Results
The incidence of RSD was 7.7% and the time to development of RSD was 62.3±34.1 days after the onset of stroke. There was no significant difference in functional status between two groups at initial and final evaluation. The upper extremity function had improved in both groups although the length of stay was longer in patient group. SSEP abnormalities were more frequent in the patient group.

Conclusion
The presence of well-managed RSD affected neither the functional status nor the functional recovery of upper extremity in stroke patients. (J Korean Acad Rehab Med 2003; 27: 480-484)
