Abstract：
We assessed the feasibility of implementing a virtually guided Neuromuscular Electrical Stimulation (NMES) protocol over the tibialis anterior (TA) muscle while collecting heart rate (HR), Numeric Pain Rating Scale (NPRS), and quality of contraction (QoC) data. We investigated if HR, NPRS, and QoC differ ON and OFF the TA motor point and explored potential relationships between heart rate variability (HRV) and the NPRS. Twelve healthy adults participated in this cross-sectional study. Three NMES trials were delivered ON and OFF the TA motor point. HR, QoC, and NPRS data were collected. There was no significant difference in HRV ON and OFF the motor point (p > 0.05). The NPRS was significantly greater OFF the motor point (p < 0.05). The QoC was significantly different between motor point configurations (p < 0.05). There was no correlation between the NPRS and HRV (p > 0.05, r = -0.129). We recommend non-electrical methods of measuring muscle activity for future studies. The NPRS and QoC can be administered virtually. Time-domain HRV measures could increase the validity of the protocol. The variables should be explored further virtually to enhance the protocol before eventual ICU studies.
摘要：
我们评估了在收集心率（HR）的同时在胫骨前（TA）肌肉上实施虚拟引导的神经肌肉电刺激（NMES）方案的可行性，数字疼痛评定量表（NPRS），和收缩质量(QoC)数据。我们调查了HR,NPRS,和QoC在TA运动点的ON和OFF之间存在差异，并探索了心率变异性（HRV）与NPRS之间的潜在关系。12名健康成年人参加了这项横断面研究。三个NMES试验在TA运动点进行了开和关。HR,QoC,收集NPRS数据。HRVON和OFF运动点差异无统计学意义(p>0.05)。NPRS明显大于运动点（p<0.05）。运动点配置之间的QoC存在显着差异（p<0.05）。NPRS与HRV无相关性(p>0.05,r=-0.129)。我们建议在未来的研究中使用非电学方法测量肌肉活动。可以虚拟地管理NPRS和QoC。时域HRV措施可以提高协议的有效性。在最终的ICU研究之前，应进一步探索变量以增强协议。
