探讨短时程周围神经电刺激（st-PNS）治疗带状疱疹后神经痛（PHN）的有效性与安全性。

回顾性分析上海中医药大学附属市中医医院神经外科自2023年10月至2024年10月接受st-PNS治疗的15例PHN患者的临床资料。采用数字评分表（NRS）评估患者的疼痛程度，采用抑郁自评量表（SDS）和焦虑自评量表（SAS）评估患者的心理状态。收集并分析患者的性别、年龄、疼痛病程、术前SAS评分、术前SDS评分、电刺激时间、围术期NRS评分及术后NRS改善率等资料，分析st-PNS的临床治疗效果，记录不良反应的发生情况。

本组患者的刺激时间范围为7~16 d，中位数（四分位数）为14（13，15） d；术前NRS评分范围为7~10分，中位数（四分位数）为8（7，9）分，术后NRS评分平均2.27分。所有患者的疼痛程度较术前均有改善，有效率100%，NRS平均下降（5.87±1.25）分；手术后NRS平均改善率73.20%±18.15%。本组患者术前SDS平均37.27分，术前SAS 20~75分，中位数（四分位数）为32（23，58）分。术前NRS、SDS、SAS评分与NRS改善率呈负相关（r=-0.517，P=0.048；r=-0.928，P<0.001；r=-0.895，P<0.001）。本组患者中无感染及其他不良反应发生。

st-PNS可以安全有效地改善PHN，但治疗效果受到术前NRS、SDS、SAS评分等因素的影响。

To investigate the technical methods, effectiveness and safety of short-course peripheral nerve stimulation (st-PNS) in the treatment of postherpetic neuralgia (PHN).

The clinical data of fifteen patients with PHN treated with st-PNS from October 2023 to October 2024 were collected retrospectively. Numeric rating scale (NRS) was used for pain scoring, self-rating depression scale (SDS) and self-rating anxiety scale (SAS) was used for evaluation of psychological status. The data of gender, age, the duration of pain, preoperative SAS, preoperative SDS, the time of st-PNS, perioperative NRS and the improvement rate of NRS were collected and analyzed, to evaluate the effectiveness and side effects of st-PNS, and the related Factors-of the rate of NRS improvement.

The stimulation time of this group of patients ranged from 7 to 16 d, with a median (quartile) of 14 (13, 15) d; The preoperative NRS score ranged from 7 to 10 points, with a median (quartile) of 8 (7, 9) points, mean postoperative NRS was 2.27 points. The pain degree of all patients was improved compared with that before operation, the effective rate was 100%, and the mean decline of NRS was (5.87±1.25) points, the mean improvement rate of NRS after surgery was 73.20%±18.15%. The average preoperative SDS score was 37.27, the preoperative SAS score was 20-75, and the median (quartile) score was 32 (23, 58). There was a significant correlation between preoperative NRS, preoperative SDS, and preoperative SAS and improvement rate of NRS (r=-0.517, P=0.048; r=-0.928, P<0.001; r=-0.895, P<0.001). There was no infection or other adverse reactions had happened.

st-PNS is safe and effective in improving PHN, but the effectiveness is affected by factors such as preoperative NRS, preoperative SDS, and preoperative SAS.
