摘要:


文题释义:

惯性传感器:由加速度计、陀螺仪和磁传感器以及融合算法(例如卡尔曼滤波器)组成。可以将惯性传感器附加到身体关节部分,用来估计该部分在空间中的运动。当与相邻肢体上的其他惯性传感器结合使用时,可以系统地进行运动学分析。可不依赖任何外部基础设施和其他环境信息,是一种经济高效的选择,并为相关研究提供了新的方向。
膝关节功能评估:主要通过相关设备在膝关节运动过程中对关节角度和时间特征进行测量,用于监测步态力学、下肢关节活动范围和肌肉力量。重点是以有意义的数据(如角度、活动范围、运动和方向)的形式跟踪和记录关节活动,这些数据可以用来估计膝关节健康状态并提供反馈。

背景:全球老龄化进程的加速及术后患者的科学康复计划等需求使医生迫切需要一种有效且低成本进行早期诊断肢体疾病的解决方案。惯性传感器因其体积小、成本低,并且与金标准(3D运动捕捉系统)相比仍然具有较高的准确性等优点在近年来倍受关注。此类监测关节活动和健康状况的可穿戴设备可以记录并提取重要参数,从而尽早治疗与运动有关的问题。
目的:总结近年来可穿戴惯性传感器在评估膝关节功能中的应用与进展,并对该领域未来发展前景及所面临的挑战进行了展望。
方法:以“Wearable, Inertial Sensors,Knee Joint, Rehabilitation, Kinesiology”为英文检索词,以“可穿戴,惯性传感器,膝关节,康复,运动学”为中文检索词,使用计算机在CNKI、万方数据库、PUBMED、FMRS检索关于惯性传感器评估膝关节的相关文章,时间要求为2005至2021年,并进行系统的归纳、总结和分析,对可穿戴惯性传感器在人体膝关节功能评估应用的研究新进展及挑战进行全面阐述。

结果与结论:通过可穿戴惯性传感器有望以非侵入性的方式跟踪和评估膝关节功能,可用以跌倒检测和预防、运动员成绩评估和康复进展等动态评估。惯性传感器有助于肢体疾病的早期诊断,并在需要时进行更有效的医疗干预,以促进术后患者早期功能恢复。可穿戴惯性传感器对人体膝关节功能的评估应用研究虽然取得较大进展,但是其存在的某些问题限制和阻碍了其在临床上的应用。未来需要更多工作从医学、用户和商业的角度来提高系统的接受度。

Abstract: BACKGROUND: With the acceleration of the global aging process and the scientific rehabilitation plan of postoperative patients, we urgently need an effective and low-cost solution for early diagnosis of limb diseases. Inertial sensor has attracted much attention in recent years, because of its small size, low cost and high accuracy compared with the gold standard (3D motion capture system). Such wearable devices that monitor joint activity and health can record and extract important parameters to treat exercise-related problems as soon as possible.
OBJECTIVE: To summarize the application and progress of wearable inertial sensors in the evaluation of knee function in recent years, and look forward to the future development prospects and challenges in this field.
METHODS: Search words were “wearable, inertial sensors, knee Joint, rehabilitation, kinesiology” in English and Chinese. Relevant literature on inertial sensor evaluation of knee joint published from 2005 to 2021 was searched by computer in CNKI, Wanfang database, PubMed and FMRS database. Systematic summary, summary and analysis were conducted to comprehensively describe the new progress and challenges in the research on inertial sensor evaluation of human knee joint. 
RESULTS AND CONCLUSION: The inertial sensor is expected to track and evaluate knee joint function in a non-invasive way, which can be used for dynamic evaluation of fall detection and prevention, athlete performance evaluation and rehabilitation progress. Inertial sensors contribute to the early diagnosis of limb diseases and carry out more effective medical intervention when needed to promote the early functional recovery of postoperative patients. Although great progress has been made in the application of wearable inertial sensor to evaluate the function of human knee joint, some problems limit and hinder its clinical application. In the future, more work is needed to improve the acceptance of the system from a medical, user and business point of view.

Key words: wearable, inertial sensor, knee joint, rehabilitation, kinesiology
