Multiple obstacle avoidance induces a higher potential of falls among older adults. This study attempted to add other important measurements by investigating the pressure-related gait parameters when stepping over multiple obstacles on a portable pressure-sensing walkway. Twenty-six young and 26 older participants were recruited in this study. A portable pressure-sensing Zeno walkway and cyclogram intersection point analysis method was introduced to collect both spatial–temporal and pressure-related gait parameters. Older adults significantly reduced foot integrated pressure of the leading leg when stepping over the second obstacle compared with young adults (p = .0078). A significantly larger cyclogram intersection point shift in medial–lateral direction was found in older adults than in young adults (p = .024) when stepping over the second obstacle, especially in the lateral direction. The results of this study showed that a pressure-sensing walking combined with cyclogram intersection point method could detect foot pressure distribution differences caused by aging.

多重障碍物回避导致老年人跌倒的可能性更高。本研究试图通过调查在便携式压力感应人行道上跨过多个障碍物时与压力相关的步态参数来增加其他重要测量值。本研究招募了 26 名年轻参与者和 26 名年长参与者。引入了一种便携式压力感应 Zeno 人行道和圆图交叉点分析方法来收集时空和压力相关的步态参数。与年轻人相比，老年人在跨过第二个障碍物时显着降低了前腿的足部综合压力 ( p  = .0078)。与年轻人相比，老年人在内侧-外侧方向上的环图交叉点偏移明显更大（p  = .024) 当跨过第二个障碍物时，尤其是在横向方向上。本研究结果表明，压力感应步行结合圆图交点法可以检测因老化引起的足部压力分布差异。
