摘要：

背景：研究认为造成老年人跌倒的相关危险因素包括肌肉无力、步态、平衡能力、视觉及认知功能障碍等。
目的：对比分析老年人自然步态下足底压力的特征。
方法：运用比利时Footscan足底压力分布测试系统分别对30名老年男性和30名青年男性进行自然行走步态测试，进行对比分析，认识老年人足底压力的变化特征。
结果与结论：老年组左、右足各区域峰力值小于青年组(P < 0.05)；老年组左、右足足底各区域的负荷率均小于青年组(P < 0.05)；老年组与青年组左足足底各区域的冲量统计学比较在第1趾骨、第2~5趾骨、第1跖骨、第2跖骨、第4跖骨、足跟内侧、足跟外侧7个区域差异有显著性意义(P < 0.05)，右足足底各区域的冲量统计学比较在10个区域差异均有显著性意义(P < 0.05)。结果说明老年人足底压力分布特征与青年人有较大区别，这些区别可能是增加老年人跌倒风险的重要因素。

Abstract:

BACKGROUND: Risk factors for fall injury in the elderly include muscle weakness, gait, balance ability, and visual and cognitive dysfunction.
OBJECTIVE: To learn the characteristics of foot pole pressure in the elderly with nature gait.
METHODS: Flat panel type Footscan foot pole pressure test system (Belgium) was used to study the difference between old men (n=30) and young men (n=30) during natural walking. The data were contrasted and analyzed to learn the characteristics of foot pole pressure in the elderly.
RESULTS AND CONCLUSION: The peak torque of foot and load rate in the old men were lower than those in the young men (P < 0.05). In comparison of impulse in the left foot, the disparity appeared in seven districts (P < 0.05), including toe 1, toes 2-5, meta 1, meta 2, meta 3, heel medial and heel lateral. In the right foot, there were significant differences in impulse in all 10 districts (P < 0.05). The results showed that the characteristics of foot pole pressure in the elderly significantly differ from those in the young, and these differences may be the important factors to increase the fall risk in the elderly.
