This study aims to investigate the concurrent validity and intrarater reliability of the Microsoft Kinect to measure thoracic kyphosis against the Flexicurve. Thirty-three healthy individuals (age: 31±11.0 years, men: 17, height: 170.2±8.2 cm, weight: 64.2±12.0 kg) participated, with 29 re-examined for intrarater reliability 1-7 days later. Thoracic kyphosis was measured using the Flexicurve and the Microsoft Kinect consecutively in both standing and sitting positions. Both the kyphosis index and angle were calculated. The Microsoft Kinect showed excellent concurrent validity (intraclass correlation coefficient=0.76-0.82) and reliability (intraclass correlation coefficient=0.81-0.98) for measuring thoracic kyphosis (angle and index) in both standing and sitting postures. This study is the first to show that the Microsoft Kinect has excellent validity and intrarater reliability to measure thoracic kyphosis, which is promising for its use in the clinical setting.
本研究旨在调查微软Kinect与Flexicurve测量胸椎后凸的同时效度和同一评估者内信度。33名健康个体（年龄：31±11.0岁，男性17名，身高：170.2±8.2厘米，体重：64.2±12.0千克）参与研究，其中29人在1至7天后接受复测以评估同一评估者内信度。在站立和坐姿下，依次使用Flexicurve和微软Kinect测量胸椎后凸。计算后凸指数和角度。微软Kinect在测量站立和坐姿下的胸椎后凸（角度和指数）方面显示出出色的同时效度（组内相关系数=0.76 - 0.82）和信度（组内相关系数=0.81 - 0.98）。本研究首次表明，微软Kinect在测量胸椎后凸方面具有出色的效度和同一评估者内信度，这使其在临床环境中的应用前景广阔。
