Using a system for motion analysis, linear correlation of speed and forelimb lameness was measured in 16 horses trotting on a treadmill at a minimum of three different trotting speeds. Forelimb lameness was determined as asymmetry of vertical head motion during left and right forelimb stance. In seven horses with a moderate forelimb lameness (head motion asymmetry >40%), lameness increased significantly with trotting speed. In a further seven horses with mild or subclinical forelimb lameness (head motion asymmetry <40%) and in two horses with a moderate forelimb lameness, no significant correlation between speed and motion asymmetry was found. The results indicate that moderate forelimb lameness measured as head motion asymmetry depends on the speed at which the measurements are taken. If head motion asymmetry is measured at two trotting speeds, it can be standardized to any speed within the trotting speed range.
使用运动分析系统，在16匹马以至少三种不同小跑速度在跑步机上小跑时，测量了速度与前肢跛行的线性相关性。前肢跛行被确定为左右前肢站立期间垂直头部运动的不对称性。在7匹患有中度前肢跛行（头部运动不对称>40%）的马中，跛行随着小跑速度显著增加。在另外7匹患有轻度或亚临床前肢跛行（头部运动不对称<40%）的马和2匹患有中度前肢跛行的马中，未发现速度与运动不对称之间存在显著相关性。结果表明，以头部运动不对称测量的中度前肢跛行取决于测量时的速度。如果在两个小跑速度下测量头部运动不对称，则可以将其标准化为小跑速度范围内的任何速度。
