In this pilot study, to assess the optimal stimulation parameters, 3 different forms of transcutaneous electrical nerve stimulation were performed in 27 patients. Conventional continuous stimulation with a constant frequency of 70 Hz, burst stimulation (90 msec trains of pulses with an internal frequency of 100 Hz repeated at 2 Hz, each train consisting of 10 pulses), and frequency-modulated stimulation (continuous pulses changed from 90 Hz to 55 Hz over 90 msec) were randomly delivered to the patients for half an hour in 3 separate sessions. The patients were blind to the modes of stimulation. This pilot study demonstrated that patients preferred modulated stimulation modes such as frequency modulation and burst rather than conventional constant mode.
在这项试点研究中，为评估最佳刺激参数，对27名患者进行了3种不同形式的经皮电神经刺激。分别以70赫兹恒定频率进行常规连续刺激、进行爆发式刺激（90毫秒的脉冲序列，内部频率为100赫兹，以2赫兹重复，每个序列由10个脉冲组成）以及进行调频刺激（在90毫秒内连续脉冲从90赫兹变为55赫兹），并在3个独立疗程中随机对患者进行半小时的刺激。患者对刺激模式不知情。这项试点研究表明，患者更喜欢调频和爆发式等调制刺激模式，而非传统的恒定模式。
