Abstract：
[Purpose] Belt electrode-skeletal muscle electrical stimulation (B-SES) is a novel electrical muscle stimulation treatment that causes less pain and discomfort and induces contraction in a wider skeletal muscle area than conventional electrodes. However, the stimulation intensity depends on patients\' subjectivity. In the present study, B-SES and an expiratory gas device were combined to analyze the kinesiophysiological data associated with changes in subjective intensity. [Participants and Methods] Seventeen healthy participants were recruited. The subjective intensities were set to four conditions (weak, normal, strong, and maximum tolerated intensity), and the stimulation was performed in each condition in the \"metabolic mode\" (frequency, 4 Hz; pulse width, 250 µs). The primary outcome was metabolic equivalents (METs), and this data were compared for each condition. [Results] METs generated by B-SES were 2.0 (1.0) for weak intensity, 2.7 (1.2) for normal intensity, 3.9 (1.3) for strong intensity, and 5.0 (1.3) for the tolerance limit intensity; differences detected between all subjective intensities were statistically significant. [Conclusion] These findings show that objective intensities of >3 METs, as recommended in rehabilitation prescriptions, can be achieved when the subjective intensity is set at strong or maximum tolerated. Treatment with B-SES may provide a viable alternative to therapeutic exercise.
摘要：
[目的]带电极-骨骼肌电刺激(B-SES)是一种新型的电肌肉刺激治疗方法,与传统电极相比,其引起的疼痛和不适更少,并在更宽的骨骼肌区域引起收缩。然而,刺激强度取决于患者的主观性。在本研究中,将B-SES和呼气气体装置结合起来分析与主观强度变化相关的运动生理数据。[参与者和方法]招募17名健康参与者。主观强度设置为四个条件(弱，正常,坚强,和最大耐受强度)，并且在每种条件下以“代谢模式”(频率，4Hz;脉冲宽度,250µs）。主要结果是代谢当量（MET），并对每种情况下的数据进行了比较。[结果]对于弱强度，B-SES产生的MET为2.0(1.0)，2.7（1.2）正常强度，3.9（1.3）强度强，和5.0（1.3）的公差极限强度；所有主观强度之间检测到的差异具有统计学意义。[结论]这些发现表明，>3MET的客观强度，根据康复处方的建议，当主观强度设置在强或最大耐受时，可以实现。B-SES治疗可能为治疗性锻炼提供可行的替代方案。
