The aim of this study was to perform gait analysis using a pressure-sensitive walkway in dogs submitted to high (total) or low amputation (partial) of one forelimb or hindlimb.
A total of 39 dogs met the inclusion criteria. The reasons for the amputations were motor vehicle accidents in 38 dogs and possible limb malformation in 1 dog. The amputee dogs were divided into four groups: G1 ( = 10)-high forelimb; G2 ( = 10)-low forelimb; G3 ( = 9)-high hindlimb; and G4 ( = 10)-low hindlimb. For kinetic evaluation, the dogs were walked across a pressure-sensitive walkway.
In dogs with forelimb amputation, the percentage of body weight (%BW) distribution on the contralateral forelimb was 50.7% in cases of high amputation and 55.5% in cases of low amputation, while the %BW distribution on the hindlimbs, mainly in the ipsilateral hindlimb, was 27.9% in cases of high amputation and 27.1% in cases of low amputation. In cases of high amputation of the hindlimb, the %BW distribution was 71.5% on the forelimbs and 29.7% on the contralateral hindlimb, while in cases of low amputation, the distribution was mainly for the contralateral hindlimb and ipsilateral forelimb. No statistical difference was noted between the amputation levels, except for the contralateral limb in cases of low and high amputation of the hindlimbs concerning the overload percentage and %BW distribution.
The amputation level of one forelimb did not influence the %BW distribution; however, in the hindlimb, this was higher for the contralateral limb in dogs submitted to high amputation.
本研究旨在使用压力感应式步态分析系统对一只前肢或后肢进行高（全）截肢或低（部分）截肢的犬进行步态分析。
共有 39 只犬符合纳入标准。截肢的原因包括 38 只犬的机动车事故和 1 只犬的可能肢体畸形。截肢犬分为四组：G1（=10）-高前肢；G2（=10）-低前肢；G3（=9）-高后肢；G4（=10）-低后肢。为了进行动力学评估，将犬放入压力感应式步态分析系统中行走。
在前肢截肢犬中，高截肢时对侧前肢的体重分布百分比（%BW）为 50.7%，低截肢时为 55.5%，而高截肢时后肢（主要是同侧后肢）的%BW 分布为 27.9%，低截肢时为 27.1%。后肢高截肢时，前肢的%BW 分布为 71.5%，对侧后肢为 29.7%，低截肢时主要分布在对侧后肢和同侧前肢。除了高和低后肢截肢同侧后肢的超重百分比和%BW 分布外，不同截肢水平之间没有统计学差异。
一只前肢的截肢水平不会影响%BW 分布；然而，在后肢中，高截肢犬的对侧肢体的分布更高。
