【摘要】：背景:三維步態(tài)分析作為一種客觀步態(tài)評估方法越來越廣泛應(yīng)用于臨床檢測。但尚缺乏統(tǒng)一的標(biāo)準(zhǔn)來衡量正常人的步態(tài)特征。目的:檢測中國正常青年人自然行走步態(tài)數(shù)據(jù),為臨床上異常步態(tài)的分析提供參考依據(jù)。方法:應(yīng)用英國Vicon三維運(yùn)動(dòng)捕捉系統(tǒng),對100名正常青年人進(jìn)行步態(tài)測試,得到時(shí)空參數(shù)、運(yùn)動(dòng)學(xué)參數(shù)、運(yùn)動(dòng)力學(xué)參數(shù)。結(jié)果與結(jié)論:正常青年人左右側(cè)(髖、膝、踝關(guān)節(jié)的活動(dòng)角度和垂直地板反力)曲線分布規(guī)律基本一致;髖、膝、踝關(guān)節(jié)活動(dòng)角度(最初著地角度、最大屈曲角度、最大伸展角度、矢狀面最大活動(dòng)范圍)和垂直地板反力參數(shù)(第1波峰值、谷值、第2波峰值)的左右側(cè)相比,差異無顯著性意義(P0.05)。說明建立的中國正常人步態(tài)數(shù)據(jù),可供臨床步態(tài)分析參考使用。
[Abstract]:Background: as an objective gait evaluation method, 3D gait analysis is more and more widely used in clinical detection. However, there is still a lack of uniform standards to measure the gait characteristics of normal people. Objective: to detect natural gait data of Chinese normal young people and to provide reference for clinical analysis of abnormal gait. Methods: the gait of 100 normal young people was measured by Vicon three-dimensional motion capture system, and the parameters of time and space, kinematics and kinematics were obtained. Results and conclusion: the distribution of the motion angle of the hip, knee, ankle joint and the vertical floor reaction were basically the same in the normal young people, the motion angle of the hip, knee and ankle joint (the initial landing angle, the maximum flexion angle) were basically the same. There was no significant difference between the left and right sides of the maximum stretching angle, the sagittal maximum range and the vertical floor reaction parameters (the first wave peak, the valley value, the second wave peak) (P0.05). The gait data can be used for clinical gait analysis.
