【摘要】：当今社会人口老龄化程度不断加深,亟需建立一套科学、健全的养老评估体系。建立养老评估体系的前提是对老年人的能力做出客观评估,因此利用评估设备对老年人的肢体运动进行检测分析并研究一种量化的评估方法尤为重要。在此背景下,本文利用Vicon三维运动捕捉及步态分析系统对老年人的肢体运动进行检测分析,提出了一种基于AHP-模糊综合评估模型的老年人肢体运动能力评估方法并开发相应的评估系统。首先,依据关节运动学的相关知识分析人体肢体运动机理,提取出对人体运动影响较大的关节及部位;并结合国际功能、残疾和健康分类(ICF)标准,分析老年人日常生活能力的影响因素,提出了适用于老年人群的肢体运动能力评估指标体系。其次,以该评估指标体系为依据,利用Vicon三维运动捕捉及步态分析系统这一检测设备来对受试者进行实验数据的采集与分析,从而为评估方法的研究提供量化标准与数据支持。再次,以评估指标体系与检测数据为基础,进行评估方法的研究。该方法融合了层次分析法(AHP)与模糊综合评价法(FCM),依据层次分析法研究各评估指标对肢体运动能力的影响程度,依据老年受试者的实验数据,通过模糊综合评价法来对老年受试者的肢体运动能力进行综合评估。最后,在分析了系统功能期望的基础上,将该评估方法应用到评估系统的开发中,达到了对受试者的肢体运动能力进行客观评估的目的。通过系统功能测试,系统评估结果与评估方法得到的预期结果一致。因此,本评估系统可以完成对老年受试者肢体运动能力的综合评估。
[Abstract]:Nowadays, the aging degree of the population is deepening, it is urgent to establish a set of scientific and sound old-age assessment system. The premise of establishing an old-age assessment system is to make an objective assessment of the ability of the elderly, so it is particularly important to use the assessment equipment to detect and analyze the limb movement of the elderly and to study a quantitative assessment method. Under this background, this paper uses Vicon three-dimensional motion capture and gait analysis system to detect and analyze the limb movement of the elderly. In this paper, a fuzzy comprehensive evaluation model based on AHP- is proposed to evaluate the limb motor ability of the elderly, and a corresponding evaluation system is developed. Firstly, according to the relative knowledge of joint kinematics, the movement mechanism of human limbs is analyzed, and the joints and parts which have great influence on human motion are extracted. Combined with the (ICF) standard of international classification of function disability and health this paper analyzes the influencing factors of the ability of daily living of the elderly and puts forward an index system for the assessment of motor ability of the limbs in the elderly population. Secondly, based on the evaluation index system, the Vicon three-dimensional motion capture and gait analysis system is used to collect and analyze the experimental data of the subjects, so as to provide quantitative standard and data support for the study of the evaluation method. Thirdly, based on the evaluation index system and test data, the evaluation method is studied. This method combines the analytic hierarchy process (AHP) and the fuzzy comprehensive evaluation (FCM),) to study the influence of each evaluation index on limb motor ability according to the analytic hierarchy process (AHP), and according to the experimental data of the elderly subjects. The method of fuzzy comprehensive evaluation was used to evaluate the limb motor ability of elderly subjects. Finally, on the basis of analyzing the functional expectations of the system, the evaluation method is applied to the development of the evaluation system, and the objective evaluation of the subjects' limb motor ability is achieved. Through the system function test, the result of the system evaluation is consistent with the expected result of the evaluation method. Therefore, the evaluation system can complete the comprehensive evaluation of the limb motor ability of the elderly subjects.
