Transcutaneous electrical nerve stimulation (TENS) is a non-invasive, inexpensive, self-administered technique to relieve pain.There are few side effects and no potential for overdose so patients can titrate the treatment as required.TENS techniques include conventional TENS, acupuncture-like TENS and intense TENS. In general, conventional TENS is used in the first instance.The purpose of conventional TENS is to selectively activate large diameter non-noxious afferents (A-beta) to reduce nociceptor cell activity and sensitization at a segmental level in the central nervous system.Pain relief with conventional TENS is rapid in onset and offset and is maximal when the patient experiences a strong but non-painful paraesthesia beneath the electrodes. Therefore, patients may need to administer TENS throughout the day.Clinical experience suggests that TENS may be beneficial as an adjunct to pharmacotherapy for acute pain although systematic reviews are conflicting. Clinical experience and systematic reviews suggest that TENS is beneficial for chronic pain.
经皮电刺激神经疗法（TENS）是一种用于缓解疼痛的非侵入性、低成本的自我治疗技术。其副作用极少，不存在过量用药的风险，因此患者可根据需要调整治疗。TENS技术包括传统TENS、针刺样TENS和强电流TENS。一般来说，首先使用传统TENS。传统TENS的目的是选择性激活大直径的非伤害性传入神经（A-β），以在中枢神经系统的节段水平降低伤害感受器细胞的活性和敏感性。传统TENS缓解疼痛的起效和消退都很快，当患者在电极下方感受到强烈但无痛的感觉异常时效果最佳。因此，患者可能需要全天进行TENS治疗。临床经验表明，尽管系统评价存在矛盾，但TENS作为急性疼痛药物治疗的辅助手段可能有益。临床经验和系统评价表明，TENS对慢性疼痛有益。
