Short-term acupuncture treatment may provide long-term relief in mild-to-moderate idiopathic carpal tunnel syndrome patients.
The methodology of this study involved a prospective follow-up of 77 patients with electrophysiologically confirmed mild-to-moderate idiopathic carpal tunnel syndrome (CTS) over a period of 1 year. These patients were divided random into two treatment groups: one recieved 2 weeks of prednisolone 20 mg daily followed by 2 weeks of prednisolone 10 mg daily, and the other received 8 sessions of acupuncture over 4 weeks. The long-term effects of these two treatment methods were then compared using Global symptom score (GSS) assessments and nerve conduction studies which were repeated at 7 and 13 months of the study.
The results showed that at 7 and 13 months, the percentages of patients with treatment failure, moderate improvement, and good improvement were significantly different between the two groups. The acupuncture group, in comparison to the prednisolone group, had a significantly higher number of patients showing good improvement throughout the 1-year follow-up period. The acupuncture treatment group also showed significantly better improvement in GSS, distal motor latencies, and distal sensory latencies. Significant correlation was observed between changes of GSS and all parameters of the electrophysiological assessments except for compound muscle action potential amplitude.
