摘要： 目的比较老年人与青年人行走时足底压力特征。方法采用足底压力分布测试系统对30 名年龄55~65 岁的老年人及30 名年龄18~23 岁的健康大学生平地自然行走时进行测试，包括足底压力各区域冲量、峰力值、负荷率，以及足跟内侧、外侧接触面积百分比。结果冲量左、右侧比较，老年组7 个区域有显著性差异，大学生组3 个区域有显著性差异；老年组各区域冲量值低于大学生组(P<0.05)。最大峰力值左、右侧比较，老年组6 个区域有显著性差异，大学生组3 个区域有显著性差异；老年组各区域峰力值低于大学生组(P<0.05)。负荷率左、右侧比较，老年组7 个区域有显著性差异，大学生组3 个区域有显著性差异；老年组各区域负荷率小于大学生组(P<0.05)。老年人左、右足均足跟内侧接触面积大于足跟外侧(P<0.05)，且左、右足间有显著性差异(P<0.05)；大学生左、右足均足跟内侧接触面积小于足跟外侧(P<0.05)，左、右足间无显著性差异(P>0.05)。结论老年人足底压力冲量、峰力值、负荷率均低于青年人，左右侧压力分布差异更大。

Abstract: Objective To compare the characteristics of plantar pressure between old and young people walking on flat. Methods 30 persons aged 55-65 years and 30 students aged 18-23 years were measured with a kind of plantar pressure measurement Footscan when they walked naturally, including impulse, max force, load rate of 10 regions, and distribution of the contact area of medial and lateral heels. Results The impulse was significantly different in 7 regions between both sides in the old people, and in 3 regions in the students. The impulse was significantly less in the old people than in the students (P<0.05). The max force was significantly different in 6 regions between both sides in the old people, and in 3 regions in the students. The max force was significantly less in the old people than in the students (P<0.05). The load rate was significantly different in 7 regions between both sides in old people, and in 3 regions in students. The load rate was significantly less in the old people than in the students (P<0.05). The contact area was larger in the medial heel than the lateral heel in old people group (P<0.05), and it was different between left and right foot. While the contact area was smaller in the medial heel than the lateral heel in the students (P<0.05), and there was no difference between left and right foot (P>0.05). Conclusion The impulse, max force, load rate decrease in the old people with the imbalance of distribution of the pressure between left and right.
