【摘要】 目的:分析不同体力活动水平健康老年人自然步行下足底压力特征,为足底压力的应用研究提供量化的理论依据。方法:选取60～65岁高、低体力活动水平老年人各16人,采用Footscan足底压力检测系统测量足底压力峰值、压力冲量、接触面积、负荷率等参数。结果:低体力活动水平组左足M₃区域及右足T₁、T_2～5、M₂、M₃、M₄区域压力峰值及冲量值大于高体力活动水平组,具有显著性差异（P<0.05）;低体力活动水平组足底T_2～5、M₃、MF、HM区域接触面积较高体力活动水平组有显著增加。结论:体力活动水平低的老年人足底缓冲能力弱,并且存在局部承担受力过高现象;老年人进行适量的体力活动,可以改善足底压力分布,预防足部损伤的发生。更多还原

【Abstract】 Objective:by analyzing the characteristics of plantar pressure of healthy elderly people with different levels of physical activity under natural walking,this paper provides a quantitative theoretical basis for the application of plantar pressure.Methods:16 elderly people aged 60-65 with high and low level of physical activity were selected,and the parameters of plantar pressure peak,pressure impulse,contact area and load rate were measured by Footscan plantar pressure detection system.Results:the peak pressure and impulse values of M₃ area of left foot and T₁,T_2～5,M₂,m₃,M₄ area of right foot in low physical activity level group were higher than those in high physical activity level group,with significant difference （P<0.05）;the plantar contact area of T_2～5,M₃,MF,HM area in low physical activity level group was significantly increased than that in high physical activity level group.Conclusion:the old people with low level of physical activity have weak plantar buffering ability,and there is a phenomenon that the local bearing force is too high;the old people with moderate physical activity can improve the plantar pressure distribution and prevent the occurrence of foot injury.更多还原
