最大幅度容限（MAT）已被认为是确定电流穿透深度的主要因素。然而，不同的经皮电刺激（TES）参数对MAT和不适水平的影响知之甚少。此外，关于可能影响MAT和不适的生物心理因素的信息有限。本研究的主要目的是比较TES协议与不同水平的脉冲持续时间（300秒与700秒）和频率（30 Hz与80 Hz）的MAT和健康老年人的不适的影响。本研究的探索性目的是检查颏下脂肪组织厚度，疼痛敏感性和性别与MAT和不适之间的关系。24名健康的老年人参加了这项研究。经皮电刺激被递送到颏下区域。测量每种条件下的最大振幅耐受性和不适。此外，测量每名受试者的颏下脂肪组织厚度和疼痛敏感性。短脉冲持续时间TES方案的最大幅度耐受性显著增加[F（3，69）=38.695，P
Maximum amplitude tolerance (MAT) has been known as a primary factor determining the depth of electrical current penetration. However, the effect of varying transcutaneous electrical stimulation (TES) parameters on MAT and discomfort level is poorly understood. Furthermore, limited information exists regarding the biopsychological factors that may impact MAT and discomfort. The primary aims of this study were to compare the effects TES protocol with varying levels of pulse duration (300s vs 700s) and frequency (30Hz vs 80Hz) on the MAT and discomfort in healthy older adults. The exploratory aim of this study was to examine relationships between submental adipose tissue thickness, pain sensitivity and gender with MAT and discomfort. Twenty-four healthy older adults participated in this study. Transcutaneous electrical stimulation was delivered to the submental region. Maximum amplitude tolerance and discomfort were measured for each condition. Furthermore, submental adipose tissue thickness and pain sensitivity were measured for each subject. Maximum amplitude tolerance was significantly increased for the TES protocols with short-pulse duration [F (3, 69)=38.695, P
