An application to measure static quadruped load distribution would be highly beneficial in the assessment of rehabilitation and lameness in many small animal patients. The scope of this study was to analyze the effects of confinement, location and local environment on the measurement of static quadruped load distribution as measured by the Quadruped Biofeedback System in normal dogs in order to better prescribe the use of this system. A prospective study of 20 healthy adult dogs was performed to evaluate effects on measurement on quadruped load distribution. Data collection in the form of mean load per extremity was recorded four times in five positions for a total of 20 measurements for each limb. A replicated cross-over design in which a mixed effect, repeated measures analysis of variance was used to test for main effects of treatment and end as well as their interaction. The effects of right vs. left within each end and for each end was analyzed for each treatment and significance of p < 0.01 was established. Measurements were taken from 20 healthy adult dogs with no obvious lameness at the time of data collection. Analysis by end suggests that measurements were affected in similar manners in comparable locations. Each method demonstrated consistency in measurement without any significant influence by day or session, suggesting that one standardized method be established for measurement. With standardization, the Quadruped Biofeedback System has potential use as a reliable instrument for the measurement of quadruped load distribution in dogs.
一种用于测量静态四足动物负荷分布的应用程序，在评估许多小动物患者的康复情况和跛行方面将非常有益。本研究的范围是分析限制、位置和局部环境对正常犬类使用四足生物反馈系统测量静态四足动物负荷分布的影响，以便更好地规定该系统的使用方法。对20只健康成年犬进行了一项前瞻性研究，以评估对四足动物负荷分布测量的影响。以每个肢体的平均负荷形式收集数据，在五个位置记录四次，每个肢体总共进行20次测量。采用重复交叉设计，其中使用混合效应、重复测量方差分析来测试治疗和结束的主要效应及其相互作用。分析了每种治疗方法在每个末端以及每个末端内左右之间的影响，并确定了p < 0.01的显著性。测量取自20只在数据收集时无明显跛行的健康成年犬。按末端分析表明，在可比位置的测量受到类似方式的影响。每种方法在测量中都表现出一致性，不受日期或时段的任何显著影响，这表明应建立一种标准化的测量方法。通过标准化，四足生物反馈系统有潜力作为一种可靠的仪器用于测量犬类的四足动物负荷分布。
