BACKGROUND/OBJECTIVE: The reported incidence of scoliosis among adolescents in China differs according to screening method owing to the lack of uniformity and limitations of certain techniques. We aimed to design, develop, and validate a non-invasive, accurate, portable, fast, and automated tool that would enable the measurement and storage of data during scoliosis screening.
We designed a new portable electronic scoliosis screening device (PESSD)-for the identification of adolescent scoliosis based on ergonomics theory. The device measured the axial deflection angle of the trunk of the human body using a built-in angle sensor. Data obtained using the PESSD, a traditional scoliometer manual ruler, and X-ray measurement of the Cobb angle were compared.
The PESSD exhibited more sensitive detection of small-angle scoliosis and improved repeatability compared with the scoliometer. The data obtained using the PESSD showed good correlation with Cobb angle data measured from X-ray images. All patients who were indicated to be positive for scoliosis using the PESSD were found to have clinically identifiable scoliosis from X-ray examination.
The PESSD may be able to achieve early detection of scoliosis in adolescents. It is non-invasive, highly precise, portable, easy to use, and offers automated data storage and traceability. This study is a pilot or preliminary validation study. With further, more in depth studies, the PESSD has excellent potential for transformation into an effective tool for use in large-scale screening programs for adolescent scoliosis in schools and communities.
This article is about designing a new portable electronic scoliosis screening device based on ergonomics theory. Because there are currently no uniform screening methods and standards, the results in this article could facilitate the adoption of a uniform screening tool into large-scale screening programs for adolescent scoliosis in schools and communities, preliminary examination in hospitals, and self-testing at home after parent training.
背景/目的：由于某些技术缺乏统一性和局限性，中国青少年脊柱侧弯的报告发病率因筛查方法而异。我们旨在设计、开发并验证一种非侵入性、准确、便携、快速且自动化的工具，以便在脊柱侧弯筛查期间进行数据测量和存储。
我们基于人体工程学理论设计了一种新型便携式电子脊柱侧弯筛查设备（PESSD），用于识别青少年脊柱侧弯。该设备使用内置角度传感器测量人体躯干的轴向偏转角。比较了使用PESSD、传统脊柱侧凸计手动尺以及X线测量Cobb角所获得的数据。
与脊柱侧凸计相比，PESSD对小角度脊柱侧弯的检测更敏感，且重复性更好。使用PESSD获得的数据与从X线图像测量的Cobb角数据具有良好的相关性。所有经PESSD检测显示脊柱侧弯呈阳性的患者，经X线检查均发现有临床可识别的脊柱侧弯。
PESSD可能能够实现青少年脊柱侧弯的早期检测。它是非侵入性的、高度精确的、便携的、易于使用的，并且提供自动化的数据存储和可追溯性。本研究是一项试点或初步验证研究。随着进一步更深入的研究，PESSD具有极好的潜力转化为一种有效的工具，用于学校和社区青少年脊柱侧弯的大规模筛查项目。
本文是关于基于人体工程学理论设计一种新型便携式电子脊柱侧弯筛查设备。由于目前没有统一的筛查方法和标准，本文的结果可能有助于将一种统一的筛查工具应用于学校和社区青少年脊柱侧弯的大规模筛查项目、医院的初步检查以及家长培训后的家庭自检。
