摘要:

文题释义:
运动捕捉技术:应用高速摄像机实时捕捉记录人体运动关键点的空间坐标变化轨迹,通过处理软件建立运动模型,对动作进行时空参数和运动学参数分析,探索运动规律。
各自由度的运动能力:自由度为质点在空间运动的方向,髋关节可以围绕冠状轴、矢状轴、垂直轴做前屈与后伸、外展与内收、旋内与旋外运动,具有3个自由度。运动能力指运动所具备的能力,包括运动幅度、速度、角速度、加速度等,分析运动能力,可为评估关节功能、科学锻炼、制定康复方案提供理论依据。

背景:髋关节结构复杂,在支持体质量、日常活动中起着重要的作用,尚无客观评估其运动能力的方法。
目的:分析髋关节在围绕矢状轴、冠状轴、垂直轴运动过程的时空参数,总结运动参数变化规律。
方法:选择30名受试者,通过三维动作捕捉系统,捕捉受试者髋关节前屈、后伸、外展、内收、旋内、旋外及复位的运动轨迹,计算分析不同自由度运动中的最大幅度与角度变化。
结果与结论:①通过建立髋关节运动模型,获得髋关节在矢状面、冠状面、水平面的活动范围,计算出各平面的运动极值;②导出不同平面运动中角度-时间的变化曲线,总结出髋关节运动的变化规律:髋关节在矢状面上的屈伸范围远大于冠状面的内收外展及水平面上的旋内、旋外活动;髋关节在前屈、后伸、外展、旋外运动的主动阶段角加速度较大,复位运动中加速度较小;③提示基于运动捕捉技术建立运动学模型,分析运动学数据,可为髋关节功能的准确评估、运动损伤的预防及康复、体育训练、生物力学分析等研究提供一定借鉴。

Abstract: BACKGROUND: The hip joint is a complex structure, and plays an important role in supporting weight and daily activities, and there is no objective way to assess its athletic ability.
OBJECTIVE: To analyze the time and space parameters of hip joint in the process of motion around sagittal axis, coronal axis and vertical axis, and to summarize the variation rules of motion parameters.
METHODS: Thirty subjects were selected to capture the movement track of hip forward flexion, backward extension, abduction, adduction, rotation in, rotation out and reduction through three-dimensional motion capture system, calculate and analyze the maximum amplitude and angle changes in different degrees of freedom movement.
RESULTS AND CONCLUSION: (1) By establishing the motion model of the hip joint to obtain the range of motion of the hip in the sagittal plane, coronal plane and horizontal plane. The extreme values of the motion of each plane were calculated. (2) The angle-time change curve of the motion of the hip in different planes was exported. The change rule of the motion of the hip was summarized: the flexion and extension range of the hip on sagittal plane was much larger than the adduction and abduction of the coronal plane and inward and outward rotation on a horizontal plane. The angular acceleration of the hip joint was larger in the active stages of forward flexion, backward extension, abduction and outward rotation, and the acceleration was smaller in the resetting movement. (3) The establishment of kinematic model based on motion capture technology and the analysis of kinematic data can provide some references for the accurate assessment of hip function, and the prevention or rehabilitation of injuries, sports training, biomechanical analysis and other studies.
