目的：The。目的：比较磁刺激和经皮神经肌肉电刺激（NMES）对17名正常志愿者股四头肌（OF）疼痛的影响。每种刺激模式的强度以逐步的方式增加。记录各强度水平下OF肌等长收缩的峰值扭矩值和视觉模拟评分（VAS）评分。两种刺激方式的VAS评分进行了比较，在强度产生相同的峰值torque values.Results：电和磁刺激的中位VAS评分分别为5.7和0.3。电刺激和磁刺激的VAS评分之间的中位差异为3.7（范围，1.7-8.5）。从每个受试者获得的最大峰值扭矩的平均值是在磁刺激高于电刺激（9.5 +/- 4.8与4.4 +/- 2.9 NmHz.Conclusions：磁刺激的OF肌肉产生的疼痛在相同水平的等距峰值扭矩比经皮NMES。磁刺激是经皮NMES的潜在替代方案，特别是对于感觉功能完整或残留的人。
Objective: The. objective of this study was to compare pain induced by magnetic stimulation of the quadriceps femoris (OF) muscle with that induced by transcutaneous neuromuscular electrical stimulation (NMES).Design: Magnetic stimulation and transcutaneous NMES were applied to OF muscles of 17 normal volunteers. The intensity of each mode of stimulation was increased in a stepwise manner. Peak torque values of isometric contractions of OF muscles and visual analog scale (VAS) scores were recorded at each intensity level. The VAS scores of the two stimulating modalities were compared at the intensity-generating same peak torque values.Results: The median VAS scores for electrical and magnetic stimulation were 5.7 and 0.3, respectively. The median difference between the VAS scores for electrical and magnetic stimulation was 3.7 (range, 1.7-8.5). The mean of the maximum peak torque obtained from each subject was higher in magnetic stimulation than in electrical stimulation (9.5 +/- 4.8 vs. 4.4 +/- 2.9 Nm).Conclusions: Magnetic stimulation of the OF muscle produced less pain at the same level of isometric peak torque than did transcutaneous NMES. Magnetic stimulation is a potential alternative to transcutaneous NMES, especially for persons with intact or residual sensory function.
