用于控制疼痛的脊髓后柱刺激：三年随访

Surg Neurol. 1975 Jul;4(1):146-7.

The long-term (three-year) effect of dorsal column electrical stimulation for chronic pain in a group of 30 patients was generally decreased effectiveness with time, and increased stimulation thresholds. Further animal and human studies of this technique are recommended.

对30例患者进行的一组背柱电刺激治疗慢性疼痛的长期（三年）效果显示，总体上随着时间推移效果降低，刺激阈值升高。建议对该技术进行进一步的动物和人体研究。
