SCS is considered to be of poor value in treating postherpetic pain. We have retrospectively analyzed the results obtained in 10 patients suffering from postherpetic neuralgia. An epidural electrode was implanted, aiming the tip in a position where stimulation could produce paraesthesiae over the painful area. At the end of the test period 6 out of 10 patients reporting a mean analgesia of 52.5% underwent a permanent implant. At mean follow-up (15 months) all the 6 patients were still reporting a satisfactory pain relief (74% of mean analgesia). These figures remained unchanged at the next follow-ups (max 46 months). The result of SCS in our patients, although positive in only 60% of them, are remarkably stable with time. We therefore recommend a percutaneous test trial of SCS in every case of postherpetic neuralgia resistent to medical treatment.
脊髓刺激术（SCS）被认为在治疗带状疱疹后神经痛方面价值不大。我们回顾性分析了10例带状疱疹后神经痛患者的治疗结果。植入了硬膜外电极，将电极尖端置于刺激可在疼痛区域产生感觉异常的位置。在测试期结束时，10例患者中有6例报告平均镇痛率为52.5%，并接受了永久性植入。平均随访（15个月）时，所有6例患者仍报告疼痛缓解令人满意（平均镇痛率为74%）。在接下来的随访（最长46个月）中，这些数据保持不变。我们患者中脊髓刺激术的结果虽然只有60%呈阳性，但随时间推移非常稳定。因此，我们建议对每例药物治疗无效的带状疱疹后神经痛患者进行脊髓刺激术的经皮试验。
