In order to study the mechanism of lameness transfer from fore- and hindlimb lamenesses 2 hypotheses were investigated. Hypothesis 1: Horses with a true supporting limb lameness in one hindlimb show a false supporting limb lameness in the ipsilateral forelimb. Hypothesis 2: Horses with a true supporting limb lameness in one forelimb show a false supporting limb lameness in the contralateral hindlimb. Fourteen horses with fore- or hindlimb lameness were used for this study. Each horse was measured at the trot on a treadmill with standardised speed, before and after diagnostic blocks (9 horses), or with and without induced lameness (5 horses). The head acceleration asymmetry (HAAS) and the sacrum acceleration asymmetry (SAAS) were used for quantification of fore- and hindlimb lameness respectively. Changes were documented by changes of the HAAS or the SAAS. In all 4 horses with a true hindlimb lameness a synchronous false lameness of the ipsilateral forelimb was documented. In 6 of 10 horses with a forelimb lameness a lameness transfer could be assessed according to hypothesis 2. The results of this study show, that horses with a true severe lameness in the forelimb show a false lameness in the contralateral hindlimb, and horses with a true hindlimb lameness show a false lameness in the ipsilateral forelimb. This indicates that the location of the truly lame limb can be deduced from the distribution of 2 lamenesses on a sagittal or diagonal axis.
为了研究前肢和后肢跛行的跛行转移机制，对2种假设进行了调查。假设1：一侧后肢存在真正支撑肢跛行的马匹，同侧前肢会出现假支撑肢跛行。假设2：一侧前肢存在真正支撑肢跛行的马匹，对侧后肢会出现假支撑肢跛行。本研究使用了14匹有前肢或后肢跛行的马。每匹马在跑步机上以标准化速度小跑时进行测量，在诊断性阻滞前后（9匹马），或在诱导跛行前后（5匹马）。头部加速度不对称（HAAS）和骶骨加速度不对称（SAAS）分别用于量化前肢和后肢跛行。通过HAAS或SAAS的变化记录变化情况。在所有4匹有真正后肢跛行的马中，记录到同侧前肢同步出现假跛行。在10匹有前肢跛行的马中，有6匹可以根据假设2评估出跛行转移。本研究结果表明，前肢存在真正严重跛行的马，对侧后肢会出现假跛行，后肢存在真正跛行的马，同侧前肢会出现假跛行。这表明可以根据矢状轴或对角轴上两种跛行的分布推断出真正跛行肢体的位置。
