Gait Posture. 2019 Feb;68:357-362. doi: 10.1016/j.gaitpost.2018.12.018. Epub 2018 Dec 15.
It is important to quantify a static posture to evaluate the need for and effectiveness of interventions such as physical management, physiotherapy, spinal orthosis or surgical treatment on the alignment of body segments. Motion analysis systems can be used for this purpose, but they are expensive, require a high degree of technical experience and are not easily accessible. A simpler method is needed to quantify static posture.
Assess validity and inter and intra rater reliability using an iPad with a 3-D camera to evaluate posture and postural deformity.
A 3-D model of a lying posture, created using an iPad with a 3-D camera, was compared to a Qualisys motion analysis system of the same lying posture, the latter used as the gold standard. Markers on the trunk and the leg were captured by both systems, and results from distance and angle measurements were compared.
All intra-class correlation coefficient values were above 0.98, the highest systematic error was 4.3 mm for length measurements and 0.2° for angle measurements.
A 3-D model of a person, with markers on anatomical landmarks, created with an iPad with a 3-D camera, is a valid and reliable method of quantifying static posture.
An iPad with a 3-D camera is a relatively inexpensive, valid and reliable method to quantify static posture in a clinical environment.
量化静态姿势对于评估诸如物理治疗、物理疗法、脊柱矫形器或手术治疗等干预措施对身体各节段排列的必要性和有效性非常重要。运动分析系统可用于此目的，但它们价格昂贵，需要高度的技术经验且不易获得。需要一种更简单的方法来量化静态姿势。
使用配备3D摄像头的iPad评估姿势和姿势畸形，评估其有效性以及评分者间和评分者内的可靠性。
将使用配备3D摄像头的iPad创建的仰卧姿势3D模型与相同仰卧姿势的Qualisys运动分析系统进行比较，后者用作金标准。两个系统都捕捉了躯干和腿部的标记，并比较了距离和角度测量的结果。
所有组内相关系数值均高于0.98，长度测量的最高系统误差为4.３毫米，角度测量为0.2°。
使用配备3D摄像头的iPad创建的带有解剖标志点标记的人体3D模型，是量化静态姿势的一种有效且可靠的方法。
配备3D摄像头的iPad是在临床环境中量化静态姿势的一种相对便宜、有效且可靠的方法。
