Various non-pharmacological analgesic procedures are attracting interest as a means of treating chronic pain (acupuncture, transcutaneous nerve stimulation, dorsal column stimulation, subcortical stimulation). The gate-control theory and activation of endorphin mechanisms are discussed as explanatory hypotheses for the analgesic effect. The proof of analgesic action in addition to the ever-present placebo effect is difficult. However, in unconscious, superficially anesthetized patients undergoing hysterectomy an analgesic effect of electrostimulation has been demonstrated which resulted in a significant reduction in the need for additional anesthetics. Speculation regarding the future of this method is premature in view of many unanswered questions.
各种非药物镇痛方法作为治疗慢性疼痛的手段正引起人们的兴趣（针灸、经皮神经刺激、背柱刺激、皮层下刺激）。作为镇痛作用的解释性假设，人们讨论了闸门控制理论和内啡肽机制的激活。除了始终存在的安慰剂效应外，证明镇痛作用很困难。然而，在接受子宫切除术的无意识、浅麻醉患者中，已证明电刺激具有镇痛作用，这导致对额外麻醉剂的需求显著减少。鉴于许多问题尚未得到解答，对该方法未来的推测还为时过早。
