Advances in mobile technology have led to the development of smartphones, whose applications present numerous utilities, such as the analysis of human movement based on inertial sensors. The purpose of this review was to investigate validity and reliability of smartphones in assessing the kinematics of the human spine.
A systematic search was performed on MEDLINE, Embase, Scopus, and LILACS databases, as well as manual searches. The included studies evaluated psychometric properties of smartphones in assessing kinematic variables of the spine (range of motion [ROM], speed, and acceleration). Two independent reviewers performed the selection, reading, data extraction, and risk of bias assessment of the studies.
Of the 2651 articles initially found, 9 were included and had their results for ROM analyzed. The meta-analyses for validity showed very high correlation coefficients in the evaluation of cervical flexion, extension, and lateral flexion; high ones in the evaluation of cervical rotation; and also high ones for intrarater and interrater reproducibility of all cervical movements. The meta-analyses for interrater reproducibility showed high correlation coefficients in the evaluation of lumbar flexion and very high ones for intrarater reproducibility.
The use of smartphones for assessing the ROM of cervical flexion, extension, and lateral flexion and lumbar flexion is feasible. Their use for assessing thoracic rotation is potentially viable, but further validation studies are still needed to ensure a safe use. There is a lack of validation studies that evaluate the applicability of this device in assessing other kinematic characteristics, such as speed and acceleration.
移动技术的进步催生了智能手机的发展，其应用具有诸多实用功能，例如基于惯性传感器的人体运动分析。本综述旨在研究智能手机在评估人体脊柱运动学方面的有效性和可靠性。
在 MEDLINE、Embase、Scopus 和 LILACS 数据库以及手动搜索中进行了系统搜索。纳入的研究评估了智能手机评估脊柱运动学变量（运动范围[ROM]、速度和加速度）的心理测量特性。两名独立的审查员进行了研究的选择、阅读、数据提取和偏倚风险评估。
在最初发现的 2651 篇文章中，有 9 篇被纳入，其 ROM 分析结果被纳入。验证的荟萃分析显示，在评估颈椎前屈、伸展和侧屈时具有非常高的相关系数；在评估颈椎旋转时具有高相关系数；在评估所有颈椎运动的内部和外部可重复性时也具有高相关系数。在评估腰椎前屈和内部可重复性时，内部可重复性的荟萃分析显示出高相关系数。
使用智能手机评估颈椎前屈、伸展和侧屈以及腰椎前屈的 ROM 是可行的。在评估胸椎旋转方面，它具有潜在的可行性，但仍需要进一步的验证研究来确保安全使用。缺乏验证研究来评估该设备在评估其他运动学特征（如速度和加速度）方面的适用性。
