Abstract
Objective: To measure repeatability within and between sessions of the Timed Up and Go (TUG) test in geriatric dogs and investigate associations between TUG times and home activity as measured by accelerometry.
Methods: Geriatric dogs were recruited in April 2024 to perform 2 sessions of TUG testing 20 days apart. Each session consisted of 3 trials separated by 1-minute rest periods. Dogs wore collar-mounted accelerometers between sessions. Client-specific outcome measures, including Canine Brief Pain Inventory and Liverpool Osteoarthritis for Dogs, were compared between sessions to ensure functional stability. Repeatability was evaluated using intraclass correlation and Bland-Altman approaches.
Results: 30 dogs were enrolled, of which 24 (median age, 13 years; median weight, 26 kg) met inclusion criteria for analyses. For all within- and between-sessions testing, coefficients of repeatability were < 1.63 seconds, intraclass correlation coefficients were > 0.92, and coefficients of variation were < 10%. Vigorous activity was negatively correlated with TUG times for both sessions (ρ = -0.5). No differences in client-specific outcome measures between sessions and no other correlations between activity measures and TUG times were detected.
Conclusions: The TUG test is repeatable within and between sessions in functionally stable geriatric dogs; however, differences of 2 seconds or less may represent normal variation. In-clinic TUG times correlate to vigorous activity at home, and both measures may be reflective of short-duration maximal capacity effort.
Clinical relevance: This study further supports the TUG test as a reliable and valid measure of canine geriatric function.
目的：测量老年犬的上跑时间（Timed Up and Go， TUG）测试内和之间的重复性，并研究TUG时间与加速度计测量的家庭活动之间的关系。方法：于2024年4月招募老年犬，每隔20天进行2次TUG测试。每组由3个试验组成，中间间隔1分钟的休息时间。狗在训练间隙戴着项圈上的加速度计。客户特定的结果测量，包括犬短暂疼痛量表和犬利物浦骨关节炎，在会议之间进行比较，以确保功能稳定性。使用类内相关性和Bland-Altman方法评估重复性。结果：共纳入30只犬，其中24只(中位年龄13岁；中位体重26公斤)符合纳入分析标准。组内和组间试验的重复性系数< 1.63秒，组内相关系数< 0.92，变异系数< 10%。剧烈运动与TUG次数呈负相关（ρ = -0.5）。在会话之间，客户特定的结果测量没有差异，在活动测量和TUG时间之间没有发现其他相关性。结论：在功能稳定的老年犬中，TUG测试可重复进行；然而，2秒或更短的差异可能代表正常变化。门诊TUG次数与家中剧烈活动相关，两种测量都可能反映短时间的最大能力努力。临床相关性：本研究进一步支持TUG测试作为犬老年功能可靠有效的测量方法。
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.
