Range of motion (ROM) measurement is an important part of physical therapy assessment and patient progress. Smartphones are user-friendly instruments and if proven to be reliable and valid, clinicians can use them for a variety of tasks including ROM measurement.
To determine concurrent validity and intra- and inter-rater reliability of the PhysioMaster application in measuring cervical ROM in both Android and iOS operating systems.
Forty-five healthy individuals (age 31.75 ± 11.94 yrs; 18 men, 27 women) completed this study. Two raters measured cervical ROM, three times each, using an Android phone for intra-rater and inter-rater reliability. With an interval time of 1-7 days after the first session, measurements were repeated by one of the raters once to measure intersession reliability. Validity was estimated by one of the raters using iPhone and Android phones one at a time while 3D motion analysis (3DMA) recorded cervical movements simultaneously. For reliability, intraclass correlation coefficient (ICC), and for validity, Pearson correlation coefficient and Bland-Altman plots were used.
ICC values of ≥0.76 and ≥0.84 demonstrated excellent intra-rater and inter-rater reliability, respectively. For concurrent validity, correlation between each phone and 3DMA was nearly perfect for all movements (0.93 ≤ r ≤ 0.97).
PhysioMaster appears to be a valid and reliable application for measuring cervical ROM in healthy individuals.
运动范围（ROM）测量是物理治疗评估和患者进展的重要组成部分。智能手机易于用户使用，如果被证明可靠且有效，临床医生可以将其用于各种任务，包括 ROM 测量。
确定 PhysioMaster 应用程序在 Android 和 iOS 操作系统中测量颈椎 ROM 的同时效度和内部及外部评分者信度。
45 名健康个体（年龄 31.75±11.94 岁；18 名男性，27 名女性）完成了这项研究。两名评分者使用 Android 手机进行三次颈椎 ROM 测量，以评估内部和外部评分者信度。在第一次测量后的 1-7 天间隔时间内，其中一名评分者重复测量一次以评估组间信度。一名评分者使用 iPhone 和 Android 手机依次进行测量，同时 3D 运动分析（3DMA）同时记录颈椎运动，以评估有效性。对于可靠性，使用组内相关系数（ICC），对于有效性，使用 Pearson 相关系数和 Bland-Altman 图。
ICC 值≥0.76 和≥0.84 分别表明了极好的内部和外部评分者信度。对于同时效度，每种手机与 3DMA 之间的相关性在所有运动中都近乎完美（0.93≤r≤0.97）。
PhysioMaster 似乎是一种用于测量健康个体颈椎 ROM 的有效且可靠的应用程序。
