目的：观察电针疏密波干预治疗面瘫急性期的临床疗效。方法：选择100 例面瘫急性期患者进行 前瞻性研究，根据随机数字表法分为对照组和观察组各50 例。2 组均行常规对症治疗方案联合电针治疗，对 照组选择连续波，观察组选择疏密波。连续治疗6 d 后休息1 d 为1 个疗程，2 组均治疗4 个疗程，后遗症期 间对患者进行为期6 个月的电话随访。评估2 组随访结束后的疗效，比较2 组治疗前（T0）、进入恢复期 第1 天（T1）、进入后遗症期第1 天（T2） 时面神经F 波运动潜伏期时限和诱发复合肌肉动作电位（CMAP） 的 波幅以及面神经传导速度。比较2 组治疗前及随访结束后的面部残疾指数（FDI），比较2 组治疗前后血清中 免疫球蛋白A（IgA）、免疫球蛋白G（IgG）、免疫球蛋白M（IgM） 含量。结果：观察组总有效率为98.00%， 高于对照组86.00%（P＜0.05）。T1、T2 时，观察组F 波时限和F 波波幅均低于对照组（P＜0.05），患侧神经传 导速度均高于对照组（P＜0.05）。随访结束后，2 组躯体功能评分较治疗前升高，社会生活功能障碍评分较治 疗前降低（P＜0.05）；且观察组躯体功能评分高于对照组，社会生活功能障碍评分低于对照组（P＜0.05）。治 疗后，2 组血清IgA、IgG、IgM 含量较治疗前降低（P＜0.05），且观察组血清IgA、IgG、IgM 含量低于对照 组（P＜0.05）。结论：电针疏密波干预对面瘫急性期患者疗效较好，可有效降低面肌麻痹程度，减少机体炎症 反应从而改善神经水肿和促进神经损伤修复，进而改善面肌功能。
Abstract：Objective：To observe the clinical effect of electroacupuncture density wave for facial palsy in acute stage. Methods：A prospective study was conducted on 100 patients with acute facial paralysis， who were divided into the control group and the observation group according to the random number table method，with 50 cases in each group. Both groups received routine symptomatic treatment combined with electroacupuncture； the control group received continuous wave therapy and the observation group received density wave therapy. Both groups were treated for four courses， with 6 consecutive days of treatment and 1 day of rest being one course of treatment. Patients were followed up by phone for 6 months during the sequelae period. The curative effects after follow- up were evaluated in the two groups. The latency time of facial nerve F- wave movement， amplitude of compound muscle action potential (CMAP)，and facial nerve conduction velocity were compared before treatment (T0)，on the first day of recovery period (T1)， and on the first day of sequelae (T2). The facial disability index (FDI) before treatment and after follow- up， and the levels of immunoglobulin A (IgA)， immunoglobulin G (IgG)， and immunoglobulin M (IgM) in serum before and after treatment were compared between the two groups. Results：The total effective rate was 98.00% in the observation group，higher than that of 86.00% in the control group (P＜0.05). At T1 and T2， the F- wave duration and amplitude in the observation group were lower than those in the control group (P＜0.05)，and the nerve conduction velocity on the affected side was higher than that in the control group (P＜0.05). After the follow-up，the physical function scores in the two groups were increased when compared with those before treatment，and the social life dysfunction scores were decreased when compared with those before treatment (P＜0.05)；the physical function score in the observation group was higher than that in the control group，and the social life dysfunction score was lower than that in the control group (P＜0.05). After treatment，the levels of IgA，IgG，and IgM in serum in the two groups were decreased when compared with those before treatment (P＜0.05)，and the levels of IgA， IgG， and IgM in serum in the observation group were lower than those in the control group (P＜0.05). Conclusion：The intervention of electroacupuncture density wave has a good curative effect in patients with acute facial paralysis， which can effectively reduce the degree of facial paralysis， reduce the body's inflammatory response， improve nerve edema， promote nerve injury repair， and thereby improve facial muscle function.
