Abstract：
With concerns about accurate diagnosis through telehealth, the Kinect sensor offers a reliable solution for movement analysis. However, there is a lack of practical research investigating the suitability of a Kinect-based system as a functional fitness assessment tool in homecare settings. Hence, the objective of this study was to evaluate the feasibility of using a Kinect-based system to assess physical function changes in the elderly.
The study consisted of two phases. Phase one involved 35 young healthy adults, evaluating the reliability and validity of a Kinect-based fitness evaluation compared to traditional physical examination using the intraclass correlation coefficient (ICC). Phase two involved 665 elderly subjects, examining the correlation between the Kinect-based fitness evaluation and physical examination through Pearson\'s correlation coefficients. A Kinect sensor (Microsoft Xbox One Kinect V2) with customized software was employed to capture and compute the movement of joint centers. Both groups performed seven functional assessments simultaneously monitored by a physical therapist and the Kinect system. System usability and user satisfaction were assessed using the System Usability Scale (SUS) and Questionnaire for User Interface Satisfaction (QUIS), respectively.
Kinect-based system showed overall moderate to excellent within-day reliability (ICC = 0.633-1.0) and between-day reliability (ICC = 0.686-1.0). The overall agreement between the two devices was highly correlated (r ≧ 0.7) for all functional assessment tests in young healthy adults. The Kinect-based system also showed a high correlation with physical examination for the functional assessments (r = 0.858-0.988) except functional reach (r = 0.484) and walking speed(r = 0.493). The users\' satisfaction with the system was excellent (SUS score = 84.4 ± 18.5; QUIS score = 6.5-6.7).
The reliability and validity of Kinect for assessing functional performance are generally favorable. Nonetheless, caution is advised when employing Kinect for tasks involving depth changes, such as functional reach and walking speed tests for their moderate validity. However, Kinect\'s fundamental motion detection capabilities demonstrate its potential for future applications in telerehabilitation in different healthcare settings.

摘要：
背景：由于担心通过远程医疗进行准确诊断，Kinect传感器为运动分析提供了可靠的解决方案。然而,缺乏实践研究来调查基于Kinect的系统在家庭护理设置中作为功能适合度评估工具的适用性.因此，本研究的目的是评估使用基于Kinect的系统评估老年人身体功能变化的可行性.
方法：本研究分为两个阶段。第一阶段涉及35名年轻健康成年人，使用组内相关系数（ICC）评估基于Kinect的适合度评估与传统体检相比的信度和效度。第二阶段涉及665名老年受试者，通过皮尔逊相关系数检验基于Kinect的体能评价与体检之间的相关性。使用带有定制软件的Kinect传感器（MicrosoftXboxOneKinectV2）来捕获和计算关节中心的运动。两组均由物理治疗师和Kinect系统同时进行了7项功能评估。使用系统可用性量表（SUS）和用户界面满意度问卷（QUIS）评估系统可用性和用户满意度，分别。
结果：基于Kinect的系统显示出总体中等至出色的日内可靠性（ICC=0.633-1.0）和日内可靠性（ICC=0.686-1.0）。对于年轻健康成年人的所有功能评估测试，两种设备之间的总体一致性高度相关（r≥0.7）。除了功能范围（r=0.484）和步行速度（r=0.493）外，基于Kinect的系统还显示出与功能评估的身体检查高度相关（r=0.858-0.988）。用户对系统的满意度良好（SUS评分=84.4±18.5；QUIS评分=6.5-6.7）。
结论：Kinect用于评估功能表现的信度和效度通常是有利的。尽管如此，对于涉及深度更改的任务，请谨慎使用Kinect，如功能延伸和步行速度测试，以获得中等有效性。然而,Kinect的基本运动检测功能证明了其在不同医疗保健环境中的远程康复中的未来应用潜力。
