Technological advances have given smartphones the capabilities of sensitive clinical measurement equipment at lesser cost and higher availability. The Clinometer is a smartphone application that can be used to measure the joint range of motion in a clinical setting, but psychometric properties of the tool's use measuring cervical range of motion (CROM) are not established.
The purpose of this study was to examine the validity and intrarater reliability of the Clinometer application for the measurement of CROM (ie, flexion, extension, rotation, lateral flexion) and to determine the minimal detectable change and SEM.
A blinded, repeated-measures correlational design was employed.
The study was conducted collaboratively between 2 athletic training clinics.
A convenience sample of healthy adults ages 18-30 years were recruited. Participants with any history in the last 3 months of cervical or thoracic pathology, pain, or any musculoskeletal injury were excluded.
Three repetitions of each motion were measured by a primary researcher with a goniometer. The same researcher then conducted 3 blinded measurements with the Clinometer application following the same procedure. A second researcher, blinded to the goniometer measurements, recorded the results. Thirty minutes later, testing was repeated with the application. The Pearson correlation was calculated to determine validity of the application compared with goniometry.
The measurements between devices had moderate to excellent concurrent validity, with the coefficients ranging between 0.544 and 0.888, P < .01. Test-retest reliability of the CROM measurement using the application was moderate to excellent, with intraclass correlation coefficients ranging between .774 and .928. Across all movements, the SEM ranged from 1.17° to 2.01°, and the minimal detectable change ranged from 1.18° to 2.02°.
The Clinometer application is a valid and reliable instrument for measuring active CROM.

技术进步使智能手机具备了成本更低、可用性更高的敏感临床测量设备的功能。Clinometer 是一款智能手机应用程序，可用于在临床环境下测量关节活动范围，但该工具用于测量颈椎活动范围（CROM）的心理测量学特性尚未确定。
本研究旨在检验 Clinometer 应用程序测量 CROM（即屈曲、伸展、旋转、侧屈）的有效性和内部测试者可靠性，并确定最小可检测变化和 SEM。
采用盲法、重复测量相关设计。
本研究在 2 个运动训练诊所之间合作进行。
招募了年龄在 18-30 岁之间的健康成年人的便利样本。排除了在过去 3 个月内有颈椎或胸段病史、疼痛或任何肌肉骨骼损伤的参与者。
由一名研究人员使用量角器测量每种运动的 3 次重复。然后，同一名研究人员按照相同的程序，使用 Clinometer 应用程序进行 3 次盲测。第二位研究人员，对量角器测量结果不知情，记录结果。30 分钟后，应用程序再次进行测试。Pearson 相关系数用于确定应用程序与量角器相比的有效性。
设备之间的测量具有中度到高度的同时有效性，相关系数在 0.544 到 0.888 之间，P <.01。使用应用程序进行 CROM 测量的重测信度为中度到高度，组内相关系数在 0.774 到 0.928 之间。在所有运动中，SEM 范围为 1.17°到 2.01°，最小可检测变化范围为 1.18°到 2.02°。
Clinometer 应用程序是测量主动 CROM 的有效且可靠的工具。
