The aim of this study was to evaluate the pressure distribution under three different types of harnesses used for guide dogs (designated H1, H2 and H3). The dogs (n = 8) led a trainer through a course including a range of exercises (straight line, curve left, curve right, upstairs and downstairs). All dogs were clinically sound and showed no sign of lameness. The pressures beneath the harnesses were determined by sensor strips and related to the gait. In all harnesses, the highest pressures were found in the right sternal region (H1 2.02 ± 0.6N/cm(2); H2 1.76 ± 0.4N/cm(2); H3 1.14 ± 0.5 N/cm(2)). In all other regions, the pressures were in the range of 0-1.32 N/cm(2). The right and left sternal regions were almost constantly loaded. Contrary to previous assumptions, the back regions had minimal loading. This investigation demonstrated that there were significant differences among the harnesses.
本研究的目的是评估用于导盲犬的三种不同类型背带（分别指定为H1、H2和H3）下的压力分布情况。这些狗（n = 8）带领训练员完成一系列训练项目，包括直线行走、向左转弯、向右转弯、上下楼梯。所有的狗临床状况良好，没有跛行迹象。背带下方的压力通过传感条测定，并与步态相关。在所有背带中，右侧胸骨区域压力最高（H1为2.02±0.6N/cm²；H2为1.76±0.4N/cm²；H3为1.14±0.5N/cm²）。在所有其他区域，压力范围为0 - 1.32N/cm²。左右胸骨区域几乎持续承受负荷。与之前的假设相反，背部区域负荷最小。这项研究表明，不同背带之间存在显著差异。
