Stair walking is more demanding locomotion than level walking and can aggravate discomfort of the foot. The purpose of this study is to analyze plantar pressure distribution and pressure patterns during gait cycle at stair walking compared to level walking. Thirty-five healthy males with 23.4 ± 2 years old were included in this study after examining normality. They performed level walking, stair ascending, and descending in same type of shoes. Measurements of in-shoe plantar pressure including peak pressure, pressure-time integral were done by Pedar-X system, masked 7 regions. Also, pressures in each region throughout the gait cycle were analyzed from each type of walking. Statistical analysis was performed using repeated measure one way analysis of variance. Peak pressure in all regions except for the midfoot was higher during level walking than stair walking. Pressure-time integral in the forefoot, midfoot during stair ascending, and the forefoot during stair descending was higher than level walking. In gait cycle, first peak was produced in the heel and the second peak was produced in the hallux during level walking, whereas during stair ascent, the heel and midfoot were in first peak, and the second peak was in the hallux. During stair descent, the first peak were in the forefoot and the midfoot, and the second peak was in the forefoot. In healthy young male adults, forefoot and midfoot are significant regions in the way that they have higher pressure burdens than other foot regions during stair walking.
上楼梯行走比平地行走对身体的要求更高，并且会加重足部不适。本研究的目的是分析与平地行走相比，上楼梯行走时步态周期中的足底压力分布和压力模式。在检查正常后，35名年龄在23.4±2岁的健康男性被纳入本研究。他们穿着同类型的鞋子进行平地行走、上楼梯和下楼梯。通过Pedar-X系统对鞋内足底压力进行测量，包括峰值压力、压力-时间积分，覆盖7个区域。此外，还分析了每种行走方式在整个步态周期中每个区域的压力。使用重复测量单因素方差分析进行统计分析。除中足外，所有区域的峰值压力在平地行走时均高于上楼梯行走时。上楼梯时前足、中足以及下楼梯时前足的压力-时间积分高于平地行走。在步态周期中，平地行走时足跟产生第一个峰值，拇趾产生第二个峰值，而上楼梯时，足跟和中足产生第一个峰值，拇趾产生第二个峰值。下楼梯时，第一个峰值在前足和中足，第二个峰值在前足。在健康的年轻男性成年人中，前足和中足是重要区域，因为在上楼梯行走时它们比足部其他区域承受更高的压力负担。
