Thirty-one patients suffering from intractable pain associated with chronic low back syndrome, cancer, and other disorders have been studied after an average of 6 months of treatment by electrical stimulation of the spinal cord applied using electrodes inserted through a Touhy needle into the epidural space. As judged by three different subjective rating methods, epidrual stimulation successfully relieved otherwise intractable chronic pain in from 23 to 26 of the 31 patients. Reported improvements in the ability to perform various everyday activities, and elimination of drug usage by many patients, corroborated this finding.
对31例患有与慢性下背部综合征、癌症及其他病症相关的顽固性疼痛的患者进行了研究，这些患者在通过经Touhy针插入硬膜外间隙的电极进行脊髓电刺激治疗平均6个月后接受了评估。通过三种不同的主观评分方法判断，硬膜外刺激成功缓解了31例患者中23至26例原本难以治疗的慢性疼痛。许多患者报告称日常活动能力有所改善，并且停止了用药，这证实了这一发现。
