Abstract

The purpose of this study was to determine whether inferential or low-frequency stimulation can produce a stronger and less painful contraction of the quadriceps femoris muscle in 20 healthy subjects. Both currents used a pulse rate of 50 Hz. The perceived discomfort experienced with each type of electrical stimulation was quantified by the use of a visual analogue scale. An isokinetic dynamometer (Cybex) was used to assess peak torque. Paired t-test demonstrated that inferential stimulation was perceived to be significantly less uncomfortable than low-frequency stimulation and that inferential stimulation produced a significantly greater peak torque of muscle contraction than low-frequency stimulation. This study indicates that inferential stimulation can produce an electrically induced muscle contraction which is stronger and less unpleasant than low-frequency stimulation.

[干扰与低频。两种肌肉电刺激方法的比较[j]。
本研究的目的是确定在20名健康受试者中,推断或低频刺激是否能产生更强、更少痛苦的股四头肌收缩。两种电流都使用了50赫兹的脉冲速率。通过使用视觉模拟量表来量化每种电刺激所经历的感知不适感。等速测功机(Cybex)用于评估峰值扭矩。配对t检验表明,与低频刺激相比,推理刺激产生的肌肉收缩峰值扭矩明显大于低频刺激。这项研究表明,推理刺激可以产生电诱导的肌肉收缩,这种收缩比低频刺激更强烈,更不令人不愉快。
