摘要

在过去十年中,表面肌电图在动物运动领域的应用大幅增加。然而,对于马匹的数据收集方法还没有达成共识。本研究旨在开始制定双极电极位置的建议,以收集马匹在执行动态任务时的表面肌电数据。研究人员使用线性电极阵列收集了三匹马在跑步机上小跑时的 21 块浅表肌肉数据。对数据进行了定量(信噪比(SNR)和变异系数(CoV))和定性(是否存在串扰和激活模式)评估,以比较和选择每块肌肉的电极位置。关于CoV,肌肉和马匹之间的差异比肌肉内部的差异更大。本研究首次尝试为马匹动态收缩时肌肉活动测量的双极电极位置提出建议。研究结果可能有助于提高马匹生物力学研究结果的可靠性和可重复性。

Towards standardisation of surface electromyography measurements in the horse: Bipolar electrode location

The use of surface electromyography in the field of animal locomotion has increased considerably over the past decade. However, no consensus exists on the methodology for data collection in horses. This study aimed to start the development of recommendations for bipolar electrode locations to collect surface electromyographic data from horses during dynamic tasks.

Data were collected from 21 superficial muscles of three horses during trot on a treadmill using linear electrode arrays. The data were assessed both quantitatively (signal-to-noise ratio (SNR) and coefficient of variation (CoV)) and qualitatively (presence of crosstalk and activation patterns) to compare and select electrode locations for each muscle.

For most muscles and horses, the highest SNR values were detected near or cranial/proximal to the central region of the muscle. Concerning the CoV, there were larger differences between muscles and horses than within muscles. Qualitatively, crosstalk was suspected to be present in the signals of twelve muscles but not in all locations in the arrays.

With this study, a first attempt is made to develop recommendations for bipolar electrode locations for muscle activity measurements during dynamic contractions in horses. The results may help to improve the reliability and reproducibility of study results in equine biomechanics.
