A computerized statistical analysis of 3,000 implanted electrode (multi-contact, quadripolar) combinations for epidural spinal cord stimulation therapy for the management of pain was carried out in three groups: spinal levels (20 different levels, C2-L2), spinal placement (midline and lateral) and contact separation (unipolar, bipolar with a separation of 10, 20 and 30 mm) to investigate the clinically required usage ranges (difference between the perception threshold and tolerance threshold). The usage range is relatively higher at midthoracic levels (T4-T10), and for the combinations located in midline. As the contact separation increases, the usage range increases in bipolar combinations. The usage range of unipolar combinations is higher than that of bipolar combinations with 10 and 20 mm separation, and is less than that of bipolar combinations having a separation of 30 mm.
对用于疼痛管理的3000个植入式电极（多触点、四极）组合进行了计算机统计分析，这些组合用于硬膜外脊髓刺激疗法，分为三组：脊髓节段（20个不同节段，C2-L2）、脊髓植入位置（中线和外侧）以及触点间距（单极、双极，间距分别为10、20和30毫米），以研究临床所需的使用范围（感知阈值和耐受阈值之间的差异）。胸中段水平（T4-T10）以及位于中线的组合的使用范围相对较高。随着触点间距增加，双极组合的使用范围增大。单极组合的使用范围高于间距为10和20毫米的双极组合，且低于间距为30毫米的双极组合。
