A computerized statistical analysis of 1,100 quadripolar electrode combinations used in epidural spinal cord stimulation therapy for the management of pain was carried out to investigate perception and tolerance thresholds. This analysis showed that the thresholds are higher at high-cervical, mid-cervical, mid-thoracic and low-thoracic spinal levels. It is also higher for the combinations with contacts located in the midline than those implanted laterally. As the contact separation increases, the perception and tolerance thresholds increase in bipolar combinations. Unipolar combinations have the lowest thresholds.
对用于硬膜外脊髓刺激疗法治疗疼痛的1100种四极电极组合进行了计算机化统计分析，以研究感知阈值和耐受阈值。该分析表明，在高颈段、中颈段、中胸段和低胸段脊髓水平，阈值较高。与位于中线的触点组合相比，植入在外侧的组合的阈值也更高。随着触点间距增加，双极组合的感知阈值和耐受阈值会升高。单极组合的阈值最低。
