The purpose of this study was to determine the effect of four different forms of transcutaneous electrical nerve stimulation (TENS) on sympathetic tone in healthy subjects. Twelve subjects received high frequency, low frequency, burst frequency, and placebo stimulation to one upper extremity. Treatments were given on different days. Ipsilateral and contralateral fingertip skin temperatures were measured at three intervals for each treatment: 1) after a 25-minute rest period before stimulation, 2) after a 25-minute treatment, and 3) 25-minutes posttreatment. High, low, and burst frequency TENS significantly increased sympathetic activity in the ipsilateral extremity immediately after treatment. Similar trends in temperature change were seen on the contralateral side. The effects of the three nonplacebo treatments did not differ from each other. Further research is needed to assess sympathetic effects of TENS on patient groups. The results suggest that monitoring skin temperature as part of a TENS assessment may be warranted, especially in patients with distal vascular impairments.
本研究的目的是确定四种不同形式的经皮电刺激神经疗法（TENS）对健康受试者交感神经张力的影响。12名受试者的一侧上肢接受高频、低频、疏密波频率和安慰剂刺激。治疗在不同日期进行。每次治疗在三个时间点测量同侧和对侧指尖皮肤温度：1）刺激前25分钟休息期后；2）25分钟治疗后；3）治疗后25分钟。高频、低频和疏密波频率的TENS在治疗后立即显著增加了同侧肢体的交感神经活动。对侧也观察到类似的温度变化趋势。三种非安慰剂治疗的效果彼此无差异。需要进一步研究以评估TENS对患者群体的交感神经效应。结果表明，作为TENS评估的一部分监测皮肤温度可能是必要的，特别是对于有远端血管损伤的患者。
