摘要

目的关节活动范围（ROM）是决定肌肉骨骼系统功能的因素之一。该参数必须能够以精确和可重复的方法测量和记录。本研究的目的是检验一种可穿戴运动传感器，即惯性测量单元（imu）传感器，在测量膝关节主动屈曲运动角度方面的有效性和可靠性。方法本研究是一项观察性验证研究，纳入70名年龄在18-25岁之间的健康科学学院学生。参与者的主要膝关节ROM由两位评分者用数字角计（Meloq EasyAngle）和可穿戴运动传感器（MetaMotionRL）测量。结果共纳入70例患者，其中女性40例，男性30例，平均年龄21.03±1.34岁。结果显示，评分内的ICC为0.959，评分间的ICC为0.961。在Meloq EasyAngle和MetaMotionRL运动传感器的第一等级测量中发现极好的相关性（ICC: 0.934, %95CI[0.894-0.959]）。此外，用数字测角仪测量的评分者膝关节ROM与用可穿戴运动传感器测量的评分者膝关节ROM之间存在显著的相关性(p <；0.05)。综上所述，可穿戴运动传感器MetamotionRL是一种有效可靠的测量膝关节ROM的方法。IMU运动传感器的使用对于在评估和康复干预期间监测和优化下肢运动学具有潜在的重要意义。

Validity and reliability of wearable motion sensors in knee joint range of motion measurement

Objective

Joint range of motion (ROM) is one of the factors that determine the function of the musculoskeletal system. This parameter must be able to be measured and recorded in an accurate and repeatable method. The aim of this study is to examine the validity and reliability of a wearable motion sensor, which is an inertial measurement units (IMUs) sensor, in measuring knee joint active flexion movement angles.

Methods

The study, an observational validation study, included 70 Health Sciences Faculty students between the ages of 18–25. The dominant knee joint ROM of the participants was measured by two raters with a digital goniometer (Meloq EasyAngle) and wearable motion sensors (MetaMotionRL).

Results

70 participants (40 female, 30 male) with an average age of 21.03 ± 1.34 years were included in the study. Intra-rater ICC was found to be 0.959 and inter-rater ICC was 0.961. An excellent correlation was found in the first rater's measurements of the Meloq EasyAngle and MetaMotionRL motion sensors (ICC: 0.934, %95CI [0.894–0.959]). Additionally, a significant correlation was found between the raters’ knee joint ROM measured with a digital goniometer and their ROM measured with a wearable motion sensor (p < 0.05).

Conclusion

It was concluded that the MetamotionRL device, a wearable motion sensor, is a valid and reliable method for measuring knee joint ROM. The use of IMU motion sensors is considered potentially important for monitoring and optimizing lower extremity kinematics during assessment and rehabilitation interventions.
