Objective outcome measures capable of tracking different aspects of functional recovery in dogs with acute intervertebral disc herniation are needed to optimize physical rehabilitation protocols. Normal, pre-injury distribution of body weight in this population is unknown. The aims of this study were to quantify static weight distribution (SWD) using digital scales and to establish the feasibility of different scale methods in neurologically normal, mature, chondrodystrophic small breed dogs predisposed to intervertebral disc herniation.
Twenty-five healthy, mature dogs were enrolled with a mean age of 4.6 years (SD 2.7) and a mean total body weight of 11.5 kg (SD 3.6). SWD for the thoracic and pelvic limbs and between individual limbs was acquired in triplicate and expressed as a percentage of total body weight using commercially available digital scales in four combinations: two bathroom, two kitchen (with thoracic and pelvic limbs combined), four bathroom and four kitchen (with limbs measured individually). SWD was also obtained using a pressure sensing walkway for comparison to scale data. Feasibility for each method was determined and coefficients of variation were used to calculate inter-trial variability. Mean SWD values were compared between methods using an ANOVA. The two bathroom scales method had the highest feasibility and lowest inter-trial variability and resulted in mean thoracic and pelvic limb SWD of 63 % (SD 3 %) and 37 % (SD 3 %), respectively. Thoracic limb mean SWD was higher for the PSW compared to any of the scale methods (p < 0.0001).
SWD in a population of healthy chondrodystrophic dogs was simple to obtain using inexpensive and readily available digital scales. This study generated SWD data for subsequent comparison to dogs recovering from acute intervertebral disc herniation.
需要能够跟踪患有急性椎间盘突出的狗的功能恢复的不同方面的客观结果测量方法，以优化物理康复方案。在该人群中，正常的、受伤前的体重分布情况尚不清楚。本研究的目的是使用数字秤来量化静态体重分布（SWD），并确定不同秤方法在易患椎间盘突出的神经正常、成熟、软骨发育不良的小型犬中的可行性。
25 只健康、成熟的犬被纳入研究，平均年龄为 4.6 岁（标准差 2.7），平均体重为 11.5 公斤（标准差 3.6）。采用市售数字秤以四种组合方式（两种浴室秤、两种厨房秤（将胸、后肢合并）、四种浴室秤和四种厨房秤（将四肢分别测量））重复测量三次，以总体重的百分比表示胸、后肢和四肢之间的 SWD，并与压力感应步态分析系统进行比较。还通过压力感应步态分析系统获得了 SWD，以与秤数据进行比较。确定了每种方法的可行性，并使用变异系数计算了试验间的变异性。使用方差分析比较了不同方法之间的平均 SWD 值。两种浴室秤方法的可行性最高，试验间变异性最低，导致平均胸、后肢 SWD 分别为 63%（标准差 3%）和 37%（标准差 3%）。与任何秤方法相比，PSW 系统的平均胸肢 SWD 更高（p<0.0001）。
使用价格便宜且易于获得的数字秤可以简单地获得健康的软骨发育不良犬的 SWD。本研究产生了 SWD 数据，以便后续与患有急性椎间盘突出症的狗进行比较。
