【摘要】：目的:探討一種便攜式步態(tài)分析系統(tǒng)在時(shí)空參數(shù)、多關(guān)節(jié)角度值的信度。方法:選取30例健康青年,由2名評(píng)估者進(jìn)行便攜式步態(tài)分析,記錄步頻、步幅、步速、步長(zhǎng)等時(shí)空參數(shù)和行走時(shí)矢狀面、水平面和冠狀面各關(guān)節(jié)活動(dòng)角度的最大值,采用相關(guān)系數(shù)進(jìn)行重測(cè)信度和測(cè)量者間信度的比較,評(píng)估其測(cè)量信度。結(jié)果:時(shí)空參數(shù)、矢狀面最大角度值組內(nèi)相關(guān)系數(shù)(ICC)均0.75,信度良好;水平面、冠狀面最大角度值ICC無顯著性差異或信度差。結(jié)論:該便攜式步態(tài)分析系統(tǒng)分析時(shí)空參數(shù)、矢狀面最大角度值信度良好,可良好地反映步行功能,有較好的評(píng)估價(jià)值;水平面及冠狀面關(guān)節(jié)角度值信度較低,應(yīng)用時(shí)需謹(jǐn)慎。
[Abstract]:Objective: to explore the reliability of a portable gait analysis system in space-time parameters and multi-joint angle values. Methods: a total of 30 healthy young people were selected for portable gait analysis. The spatial and temporal parameters such as gait frequency, gait, gait speed and step size were recorded, and the maximum angle of motion of sagittal plane, horizontal plane and coronal plane were recorded. Correlation coefficient was used to compare test retest reliability and inter-test reliability to evaluate the measurement reliability. Results: the time-space parameters, the correlation coefficient (ICC) of sagittal plane maximum angle group were all 0.75, the reliability was good, but there was no significant difference or poor reliability in horizontal plane and coronal maximum angle value ICC. Conclusion: the portable gait analysis system has good reliability of maximum angle value on sagittal plane, which can well reflect walking function and has better evaluation value, while the reliability of horizontal plane and coronal joint angle value is lower, so it needs to be careful in application.
