This study investigated differences in kinematic and temporospatial variables in treadmill-naïve dogs when introduced to treadmill trotting and the time required to for them to become habituated to the treadmill. Twenty-four healthy Labrador retrievers, with an age range of 22-36 months and with no history of orthopaedic disease, were included in the study. A motion capture system registered kinematic variables of the carpus, elbow, tarsus and stifle, along with stride time and stance duration, at 240 Hz. Six sessions, each lasting 8-10 min, walking and trotting on the treadmill were performed with each dog, with three sessions on each of two consecutive days. The between-stride variability of total angular displacement of the carpus, elbow, stifle and tarsus, as well as the stride and stance time, was higher during the day 1 trotting sessions than in the last session of day 2. These stabilised to non-significant levels before the second session on the second day of measurements and thus habituation was achieved.
本研究调查了初次接触跑步机的犬只在开始跑步机小跑时的运动学和时空变量差异，以及它们适应跑步机所需的时间。24只健康的拉布拉多猎犬被纳入研究，年龄在22至36个月之间，无骨科疾病史。一个运动捕捉系统以240Hz的频率记录腕关节、肘关节、跗关节和膝关节的运动学变量，以及步幅时间和站立时间。每只狗在跑步机上进行6次时长为8至10分钟的行走和小跑，连续两天每天各进行3次。腕关节、肘关节、膝关节和跗关节总角位移的步幅间变异性，以及步幅和站立时间，在第1天的小跑过程中高于第2天的最后一次训练。在测量的第二天第二次训练前，这些变量稳定到无显著差异的水平，从而实现了适应。
