수술받지 않은 수근관 증후군 환자의 추적 검사

초록

Objectives : This study was designed to evaluate the clinical and electrophysiologic changes of the nonoperated carpal tunnel syndrome (CTS) patients. Methods : Nineteen patients (35 lesions) with electrodiagnostically confirmed CTS syndrome were recruited and the follow-up electrophysiologic examination was performed 5 to 29 months (mean, 18.3 months) after the first examination. In the follow-up examination, information on the type of conservative management and the level of clinical recovery were obtained. The level of clinical recovery was defined as the patient’s present symptoms compared to symptom intensity at the first examination. Results : The reduction of symptoms was significant: complete symptom relief was noted in 11.4% and slight improvement in 60%. Distal latency and amplitude of median motor and sensory responses were not significantly improved in the follow-up examination. Comparison between the level of clinical improvement and electrophysiologic change was not statistically significant. Conclusion : In the follow-up examination, clinical improvement was observed in the 24 nonoperated carpal tunnel syndrome cases but neurophysiological variables of median nerve had not changed significantly. These findings suggest that the follow-up EMG study may be needed to evaluate the pathologic process of median nerve.
