A total of 50 patients with chronic pain syndromes were selected for treatment with spinal cord stimulation. Correct positioning of electrodes was obtained in 44 patients, leading to an initial alleviation of pain in 25 patients. In 6 patients, electrodes (though still effective in 4) had to be removed because of surgical complications within the first 5 months of use. Only 8 patients had at least some beneficial effect lasting for more than 3 years. The long-term results in patients with more severe psychological disturbances were no worse than those of the other patients.
共有50例慢性疼痛综合征患者被选入接受脊髓刺激治疗。44例患者电极定位正确，其中25例患者疼痛最初得到缓解。6例患者因在使用的前5个月内出现手术并发症而不得不移除电极（尽管其中4例仍有效果）。只有8例患者至少有持续超过3年的有益效果。心理障碍较严重患者的长期结果并不比其他患者差。
