Computer assisted gait analysis allows for the objective examination of ground reaction forces as well as the kinematic analysis of gait. At present it is unclear if there are relevant differences in the gait pattern of the hind limb of dogs during the walk on treadmill and force plate. Thus, aim of this study was the comparison of canine hind limb joint angles and certain kinematic gait cycle parameters like cadence, step and stride time as well as step length during the walk on force plate and treadmill. 19 adult dogs of different breeds were analysed. Extension and flexion of hip, stifle and hock, hip ab- and adduction and range of motion (ROM) were evaluated. Furthermore joint angles at the moment of maximum load were identified. Considering the joint angles and gait cycle parameters there were no significant differences between force plate and treadmill, except for the hip angles, the hock angle at the moment of maximum load as well as for cadence and stride time. Whereas all flexion/extension joint angles, except the maximum hock joint angle, showed a moderate to good correlation, the ROM of the analysed joint angles was in maximum moderate. In summary it could be demonstrated that the gait pattern of the canine hind limb shows similarities on force plate and treadmill. Nevertheless significant differences of certain parameters exist and in total only a fair to moderate correlation of the data between treadmill and force plate could be shown. Therefore the results of this study provide important information for the comparative interpretation of canine gait analysis carried out on force plates and treadmills.
计算机辅助步态分析可对地面反作用力进行客观检查，并对步态进行运动学分析。目前尚不清楚犬在跑步机和测力板上行走时后肢的步态模式是否存在相关差异。因此，本研究的目的是比较犬后肢关节角度以及某些运动学步态周期参数，如步频、步幅和步长，以及在测力板和跑步机上行走时的步长。对19只不同品种的成年犬进行了分析。评估了髋、膝和跗关节的伸展和屈曲、髋关节的内收和外展以及活动范围（ROM）。此外，还确定了最大负荷时刻的关节角度。考虑到关节角度和步态周期参数，除了髋关节角度、最大负荷时刻的跗关节角度以及步频和步幅时间外，测力板和跑步机之间没有显著差异。除最大跗关节角度外，所有屈伸关节角度均显示出中度至良好的相关性，所分析关节角度的活动范围最大为中度。总之，可以证明犬后肢的步态模式在测力板和跑步机上表现出相似性。然而，某些参数存在显著差异，总体而言，跑步机和测力板之间的数据仅显示出中等至中等程度的相关性。因此，本研究结果为在测力板和跑步机上进行的犬步态分析的比较解释提供了重要信息。
