Abstract
Objective: To evaluate the significance of leash attachment and device positioning along the collar of a commercial triaxial accelerometer (FitBark 2) on physical activity measurements during leashed walks in dogs.
Methods: 10 medium- to large-breed healthy dogs (1 to 11 years old) were enrolled for a 3- to 14-day period. Dogs were fitted with 2 collars with 2 devices on each (dorsolateral leash [LL], dorsolateral no leash [L-NL], ventral leash [VL], ventral no leash [V-NL]) that were worn during 6 to 11 walks where the leash was only attached to 1 designated collar. Device outputs (ie, total and average BarkPoints) were analyzed using Pearson correlation and mixed models.
Results: There was a very high correlation between all devices. Using mixed models, activity outputs did not differ between devices on leashed collars compared to their nonleashed counterparts (LL vs L-NL, VL vs V-NL) or between devices on the nonleashed collar (L-NL vs V-NL). Total and average BarkPoints differed significantly between devices on the leashed collar (LL vs VL). The total BarkPoints difference between LL and VL remained unchanged with increasing walk duration, and thus the percentage difference decreased over time.
Conclusions: Triaxial accelerometry can be used to monitor the activity of dogs during routine walks without significant interference of the leash attachment or the device position along the collar.
Clinical relevance: Leash attachment and device orientation are important variables to validate accurate long-term physical activity measurements.
目的：评价牵链附着和沿商用三轴加速度计（FitBark 2）项圈定位对狗在牵链散步时身体活动测量的意义。方法：选取10只1 ~ 11岁的中大型健康犬，为期3 ~ 14天。狗被安装了2个项圈，每个项圈上有2个装置（背外侧牵引[LL]，背外侧无牵引[L-NL]，腹侧牵引[VL]，腹侧无牵引[V-NL]），在6到11次散步中，狗只被拴在一个指定的项圈上。使用Pearson相关和混合模型分析设备输出（即总BarkPoints和平均BarkPoints）。结果：各器械间有很高的相关性。使用混合模型，拴环上的设备与未拴环上的设备（LL vs L-NL, VL vs V-NL）或未拴环上的设备（L-NL vs V-NL）之间的活动输出没有差异。总BarkPoints和平均BarkPoints在系带项圈上的设备之间存在显著差异（LL和VL）。随着行走时间的增加，LL和VL之间的总BarkPoints差异保持不变，因此百分比差异随着时间的推移而减少。结论：三轴加速度计可用于监测狗在日常散步时的活动，而不受牵引带连接或设备沿项圈位置的明显干扰。临床相关性：牵链附着和设备方向是验证准确的长期身体活动测量的重要变量。
期刊介绍：
The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
