研究了9例受试者胫骨前肌肌电信号电极-皮肤界面阻抗的变化。使用符合SENIAM推荐的表面肌电信号数据收集的双极电极配置记录表面肌电信号。使用由PC和阻抗转换电路组成的定制设备在一对双极电极之间进行阻抗测量。阻抗装置能够同时应用和记录由两个电极之间传递的已知正弦波组合构成的波形。在两个小时的时间里，每15分钟记录一次30秒，记录每位受试者踝关节背屈时最大自主力的10%。在每次表面肌电信号记录前后立即测量阻抗。所有受试者均给予书面知情同意。
Changes in the impedance at the electrode-skin interface of SEMG electrodes on the tibialis anterior were assessed in nine subjects. SEMG signals were recorded using a bipolar electrode configuration that conformed to the SENIAM recommendations for SEMG data collection. Impedance measurements were made between a pair of bipolar electrodes using a custom-built device consisting of a PC and an impedance conversion circuit. The impedance device enabled the simultaneous application and recording of a waveform constructed of a known combination of sinusoids passed between the two electrodes. SEMG recordings at 10% of each subject's maximal voluntary force during ankle dorsiflexion were made for a 30-s period every 15-min over a two hour period. Impedance was measured immediately before and after each SEMG recording. All subjects gave their written informed consent.
