目的：观察帕金森病人气功辅助治疗前后事件相关电位（ＥＲＰ）的变化。方法：对３３例药物治疗中期的帕金森病人作气功辅助治疗３个月，观察治疗前后的听觉ＥＲＰ的Ｐ３００，并与正常对照组２４例比较。结果：帕金森病人ＥＲＰ与对照组存在多指标差异，以Ｐ３潜伏期延长为甚，气功锻炼后其Ｎ２、Ｐ３潜伏期缩短，与对照组比较无显著性差异；同时临床症状也获得改善。结论：帕金森病人有认知功能受损，气功辅助治疗可使其获得改善或恢复。
Objective: To observe the changes of event related potential (ERP) before and after qigong adjuvant therapy in Parkinson’s disease patients. Methods: Thirty-three patients with Parkinson’s disease were treated with Qigong adjuvant therapy for 3 months. The P300 of auditory ERP before and after treatment was observed and compared with that of the normal control group. Results: There were multiple index differences between ERP and control group in Parkinson’s disease patients. P3 latency was prolonged. After Qigong exercise, the incubation period of N2 and P3 was shortened, showing no significant difference compared with control group. Clinical symptoms also improved at the same time. CONCLUSIONS: Parkinson’s patients have impaired cognitive function and Qigong adjuvant therapy may improve or recover them.
