Patients who underwent implantation of dorsal column stimulators from 1970 to 1973 were reviewed 7-10 years following stimulation. The number who achieved satisfactory pain relief was not significant. The criteria for selecting these patients were reviewed utilizing those now used in 1980. 50% of the patients originally selected would now be rejected for psychological or drug-related reasons. This long-term evaluation indicates no benefit to the patients treated with spinal cord stimulation. However, it appears that psychological factors were the most important reasons for failure. A smaller group of patients studied for 3-5 years following implantation of epidural spinal cord stimulators achieved a 70% pain control rate. Selection factors that explain these differences are discussed.
对1970年至1973年间接受背柱刺激器植入的患者在刺激后7至10年进行了回顾。实现满意疼痛缓解的患者数量并不显著。利用1980年现用的标准对这些患者的选择标准进行了回顾。最初选择的患者中有50%现在会因心理或药物相关原因被拒绝。这项长期评估表明脊髓刺激治疗对患者没有益处。然而，心理因素似乎是失败的最重要原因。一小群在植入硬膜外脊髓刺激器后接受了3至5年研究的患者实现了70%的疼痛控制率。讨论了解释这些差异的选择因素。
