使用10只临床健全的成年狗在跑步机上行走，每天三次，在三个不同的日子里，确定重复测量的垂直地面反作用力（GRF）变量的可靠性。测定各肢体的峰值垂直力、垂直冲量和站立期持续时间，并分析日内、日间和犬间的显著差异。使用随机效应模型（包括犬、不同日期、试验和四肢）确定GRF方差的贡献。ANOVA未显示日内和日间变量的任何显著差异，但确实显示了犬间的差异。差异主要见于不同的狗，而不同的日子和试验是不太重要的因素。得出的结论是，由跑步机系统确定的地面反作用力是合适的，并在犬步态分析中提供了可重复的参数。这样的跑步机/测力板系统允许以恒定速度行走的狗的所有四条腿的同时测量。(c)2005爱思唯尔有限公司保留所有权利。
The reliability of repeated measurements of vertical ground reaction force (GRF) variables was determined using 10 clinically sound adult dogs walking on a treadmill three times daily on three different days. Peak vertical force, vertical impulse and duration of stance phase of each limb were determined and analysed for significant differences within and between days and between dogs. Contributions to the variance of GRF were determined using a random effect model including dogs, different days, trials and extremities. ANOVA did not show any significant differences in variables within and between days, but did reveal differences between dogs. Variance was mainly seen in different dogs, whereas different days and trials were less important factors. It was concluded that the ground reaction forces determined by a treadmill system are suitable and provide reproducible parameters in canine gait analysis. Such treadmill/force plate systems allow the simultaneous measurement of all four legs of dogs at a constant velocity walk. (c) 2005 Elsevier Ltd. All rights reserved.
