With the unfortunate exception of the differential spinal block, diagnostic nerve blocking has become somewhat obsolete with the development of newer, more sophisticated diagnostic technology. Therapeutic nerve blocks remain useful in treating patients with various terminal cancers, some forms of back pain, tic douloreux, causalgia, reflex sympathetic dystrophy, and many trigger point syndromes. For dysfunctional and pain-disabled patients (rated as class 1 or 3 on Emory Pain Estimate Model), block therapy must be structured in comprehensive pain rehabilitation programs.
除了不幸的脊髓节段性阻滞这一例外情况，随着更新的、更复杂的诊断技术的发展，诊断性神经阻滞在一定程度上已过时。治疗性神经阻滞在治疗各种晚期癌症患者、某些形式的背痛、三叉神经痛、灼性神经痛、反射性交感神经营养不良以及许多触发点综合征方面仍然有用。对于功能障碍和疼痛致残的患者（在埃默里疼痛评估模型中评定为1级或3级），阻滞治疗必须纳入综合疼痛康复计划中。
