Low-frequency (2 Hz) transcutaneous electrical nerve stimulation (TNS) may produce prolonged and widespread sympatho-inhibition resulting in improved skin microcirculation with increased skin temperature in patients with peripheral vascular insufficiency. The method has previously been used successfully to improve peripheral circulation in such patients and to accelerate healing of chronic skin ulcers of various etiology. The present report deals with healing of atopic eczema and relief of pruritus by low-frequency TNS treatment in a patient who was followed for 2 years, the first 8 months with daily recordings of the effects, and then for an additional 16 months during which period TNS only occasionally was used. TNS also produced increased plasma levels of ACTH, cortisol and vasoactive intestinal polypeptides (VIP). The mechanisms of the favourable clinical effects are discussed.
低频（2赫兹）经皮电神经刺激（TNS）可能会产生持久且广泛的交感神经抑制，从而改善外周血管功能不全患者的皮肤微循环并提高皮肤温度。该方法此前已成功用于改善此类患者的外周循环，并加速各种病因引起的慢性皮肤溃疡的愈合。本报告涉及一名患者通过低频TNS治疗特应性皮炎的愈合情况及瘙痒缓解情况，该患者接受了2年的随访，前8个月每天记录疗效，随后的16个月期间仅偶尔使用TNS。TNS还使促肾上腺皮质激素、皮质醇和血管活性肠肽（VIP）的血浆水平升高。文中讨论了这些良好临床效果的机制。
