步态分析可以增强临床实践。然而，由于需要昂贵的设备，而这些设备在临床环境中并不总是可用，因此其使用受到限制。最近的证据表明，微软 Kinect 可能提供一种低成本的步态分析方法。本报告的目的是批判性地评估描述使用 Kinect 作为步态分析工具的并发有效性的文献。对 PubMed、CINAHL 和 ProQuest 数据库进行了在线检索。其中包括使用 Kinect 和另一种金标准设备评估步行的研究，并且包括至少一个时空或运动学测量的数值发现。我们的检索共找到 366 篇论文，从中检索到 12 篇相关研究。结果表明 Kinect 仅对某些时空步态参数有效。 Kinect测量的运动学参数虽然跟随关节轨迹的变化趋势，但有效性较差，误差较大。总之，Kinect 可能有潜力用作测量步态时空方面的工具，但应建立标准化方法，并且需要对健康受试者和临床参与者进行未来的检查，以便将 Kinect 整合为临床步态分析工具。
Gait analysis may enhance clinical practice. However, its use is limited due to the need for expensive equipment which is not always available in clinical settings. Recent evidence suggests that Microsoft Kinect may provide a low cost gait analysis method. The purpose of this report is to critically evaluate the literature describing the concurrent validity of using the Kinect as a gait analysis instrument. An online search of PubMed, CINAHL, and ProQuest databases was performed. Included were studies in which walking was assessed with the Kinect and another gold standard device, and consisted of at least one numerical finding of spatiotemporal or kinematic measures. Our search identified 366 papers, from which 12 relevant studies were retrieved. The results demonstrate that the Kinect is valid only for some spatiotemporal gait parameters. Although the kinematic parameters measured by the Kinect followed the trend of the joint trajectories, they showed poor validity and large errors. In conclusion, the Kinect may have the potential to be used as a tool for measuring spatiotemporal aspects of gait, yet standardized methods should be established, and future examinations with both healthy subjects and clinical participants are required in order to integrate the Kinect as a clinical gait analysis tool.
