Abstract

Objectives: To evaluate the validity and reliability of a smartphone-based application against inertial sensors to measure head repositioning (by using joint position sense -JPS) and cervical range of motion (ROM).

Methods: JPS and cervical ROM were evaluated for neck flexion, extension and both-sides lateral flexion in thirty-one volunteers. Participants were simultaneously evaluated with inertial sensors and the smartphone application. A total of 248 angles were compared for concurrent validity. Inter-tester and intra-tester reliability were evaluated through scoring of images with the smartphone application by two testers, and re-scoring images by the same tester.

Results: Very high correlation was observed between both methods for ROM in all neck movements and JPS in left-side lateral flexion (r>0.9), and high for JPS in the rest of movements (r>0.8). Bland-Altman plots always demonstrated absolute agreement. Inter-and intra-tester reliability was perfect for JPS and ROM in all the neck movements (ICC>0.81).

Conclusions: This smartphone-based application is valid and reliable for evaluating head repositioning and cervical ROM compared with inertial sensors in healthy and young adults. Health professionals could use it in an easier and portable way in field conditions.

基于智能手机的头部复位和颈椎活动范围应用程序的并发有效性和可靠性。

目的:评估基于智能手机的应用程序对惯性传感器测量头部重新定位(通过使用关节位置感-JPS)和颈椎运动范围(ROM)的有效性和可靠性。方法:对31例志愿者进行JPS和颈椎ROM对颈部屈曲、伸展和两侧侧屈的影响评估。参与者同时使用惯性传感器和智能手机应用程序进行评估。共比较248个角度的并发效度。测试者之间和测试者内部的信度通过两名测试者用智能手机应用程序对图像进行评分，以及由同一名测试者对图像进行重新评分来评估。结果:两种方法在所有颈部运动中的ROM与左侧侧屈时的JPS有很高的相关性(r>0.9)，其余运动中的JPS有很高的相关性(r>0.8)。布兰德和奥特曼的情节总是表现出绝对的一致。在所有颈部运动中，JPS和ROM的测者间和测者内信度都很好(ICC>0.81)。结论:与惯性传感器相比，这种基于智能手机的应用程序可以有效可靠地评估健康和年轻人的头部复位和颈椎ROM。卫生专业人员可以在野外条件下以更方便和便携的方式使用它。
