The aim of this study was to prove whether fluctuation of walking velocity during gait cycle is an effective index of walking ability or is not. the subject for the gait analysis are 10 healthy person, 9 person with hemiplegia, 13 person with knee osteoarthritis and 7 person with hip osteoarthritis.Result from the analysis reveal that the relative walking velocity calculated from the acceleration of hip is affected by the section length of pairwise linear regression, and condition of the appropriate section is proposed. the results obtained in this gait analysis indicated increasing standard deviation of walking velocity during a gait cycle with average walking velocity and suggest that variation coefficient is more useful for an evaluation index of the walking ability than the standard deviation.

本研究的目的是证明步态周期中步行速度的波动是否是步行能力的有效指标。步态分析对象为10名健康人、9名偏瘫患者、13名膝骨关节炎患者和7名髋骨关节炎患者。分析结果表明，根据髋部加速度计算出的相对行走速度受截面长度的影响的成对线性回归，并提出了适当部分的条件。步态分析中获得的结果表明，在平均步行速度的步态周期内，步行速度的标准偏差不断增加，这表明变异系数比标准偏差更适合作为步行能力的评估指标。
