A noninvasive computer-assisted kinematic gait analysis was used to describe flexion and extension movements of 6 joints in Greyhounds at a trot. Distinct patterns of movements were described for each joint studied. The coxofemoral and carpal joints were characterized by a single peak of maximal extension. The femorotibial, tarsal, scapulohumeral, and cubital joints had 2 peaks of maximal extension, with 1 peak preceding stance phase and a second peak within stance phase. A two-factor repeated-measures ANOVA was used to determine the variance in measurement of joint angles in degrees that was attributable to trial repetitions and to differences between dogs. The coxofemoral, femorotibial, tarsal, scapulohumeral, and cubital joints had a mean variance attributable to trial repetition of 6.6 (range, 1.7 to 12.9), and a mean variance attributable to differences between dogs of 5.1 (range, 0.9 to 9.2). The carpus had more variance, with a mean variance attributable to trial repetition of 16.3 (range, 13.3 to 20.5), and that attributable to differences between dogs of 31.8 (range, 20.5 to 46.7). Kinematic gait analysis provided a reliable description of flexion and extension movements in Greyhounds with minimal variance attributable to trial repetitions and to differences between dogs.
采用非侵入性计算机辅助运动步态分析来描述灵缇犬在小跑时6个关节的屈伸运动。对每个研究的关节都描述了不同的运动模式。股髋关节和腕关节的特征是最大伸展时有一个单峰。股胫关节、跗关节、肩胛肱关节和肘关节有两个最大伸展峰，一个峰在站立期之前，第二个峰在站立期内。采用双因素重复测量方差分析来确定以度为单位的关节角度测量值的方差，该方差可归因于试验重复和犬只之间的差异。股髋关节、股胫关节、跗关节、肩胛肱关节和肘关节因试验重复导致的平均方差为6.6（范围为1.7至12.9），因犬只之间差异导致的平均方差为5.1（范围为0.9至9.2）。腕关节的方差更大，因试验重复导致的平均方差为16.3（范围为13.3至20.5），因犬只之间差异导致的平均方差为31.8（范围为20.5至46.7）。运动步态分析为灵缇犬的屈伸运动提供了可靠的描述，因试验重复和犬只之间差异导致的方差最小。
