Joint range of motion (ROM) is an important assessment to aid diagnostic and clinical decision-making for persons with a wide variety of neuromusculoskeletal conditions. The current clinical standard for assessing ROM is the standard goniometer (SG).
The purpose of this study was to investigate the validity, reliability and time required to assess ROM using a standard goniometer (SG), medical inclinometer (MI), and builder's digital inclinometer (BI).
Cross-sectional study.
Fifty participants with no current shoulder, elbow, or forearm pain limiting movement were assessed by a single tester. The tester measured three repetitions of passive forearm and shoulder rotation with an SG, MI, and BI. Device order was randomized. Time to complete assessment with each device was measured.
BI and MI were significantly faster than the SG (p < 0.001) for all motions. Inclinometer measurements were more reliable (average ICC = 0.933 for MI and 0.919 for BI) than SG measurements (average ICC = 0.822). There was good correlation between MI and BI and mean differences between devices was less than 2°. Correlations between the SG and the inclinometers ranged from poor to fair and mean differences between devices was 4°.
The BI and MI were reliable for measuring forearm and shoulder rotation. The poor correlation between the SG and inclinometers indicates that clinicians should utilize the same device for testing. Because time can be a barrier to clinician assessment, the greater efficiency and reliability of inclinometers warrants consideration as the new measurement standard. Standard patient and inclinometer positioning is recommended to enhance reliability.

关节活动范围（ROM）是一项重要的评估，有助于对患有各种神经肌肉骨骼疾病的患者进行诊断和临床决策。目前评估ROM的临床标准是标准测角仪（SG）。
本研究的目的是调查使用标准测角仪（SG）、医用倾角仪（MI）和建筑用数字倾角仪（BI）评估ROM的有效性、可靠性和所需时间。
横断面研究。
由一名测试者对50名目前没有肩部、肘部或前臂疼痛限制运动的参与者进行评估。测试者使用SG、MI和BI对被动前臂和肩部旋转进行三次重复测量。设备顺序是随机的。测量使用每种设备完成评估的时间。
对于所有动作，BI和MI比SG显著更快（p < 0.001）。倾角仪测量比SG测量更可靠（MI的平均组内相关系数ICC = 0.933，BI的平均ICC = 0.919）（SG的平均ICC = 0.822）。MI和BI之间有良好的相关性，设备之间的平均差异小于2°。SG与倾角仪之间的相关性从差到一般，设备之间的平均差异为4°。
BI和MI在测量前臂和肩部旋转方面是可靠的。SG与倾角仪之间较差的相关性表明临床医生应使用相同的设备进行测试。由于时间可能是临床医生评估的一个障碍，倾角仪更高的效率和可靠性值得考虑作为新的测量标准。建议采用标准的患者和倾角仪定位以提高可靠性。
