摘　　要：目的 :对国人在行走和站立时足底应力分布进行研究。方法 :对 53例正常人受试者检测步态间期和行走、站立时的足底足跟、第 1～ 5跖骨头和趾七个区的应力分布进行测量。结果 :步态间期为 0 .667(s) ,行走时上述 7区的应力分别为 (1 83 .3± 47,1 61± 36 ,2 57.2± 51 ,1 99.2± 48,1 31 .8± 2 5 ,1 2 0 .4± 1 9,2 0 4± 62 )kPa;静态足底 7区应力 (kPa)分布和所占总应力的百分率各为 1 61kPa(46 .68% ) ,1 1 8.1kPa(34 .2 4 % ) ,1 4kPa(4.0 6 % ) ,9kPa(2 .61 % ) ,5kPa(1 .45 % ) ,1 8kPa(5 .2 2 % )和 1 9.8kPa(5 .74% )kPa。还对重心运行曲线在足底应力图上进行分析。结论 :此系列数据是分析诊断国人足病和下肢疾患和客观指标 ,对诊断。Objective:To study on the human foot pressure distribution of walking(dynamic) and standing(static).Methods: For quantitative measuring and real time processing of walking and standing 53 normal human feet plantar pressure distribution and the time on the seven areas of the foot,heel,heads of lst to fifth metatarsus and great toe(Gt) were presented.Results: Fifty three feet plantar pressure images were obtained at a rate of a frame during a single step of walking and standing drawed and stored in the memory.These frams could be displayed on a colour monitor and plotted either as colour isopressure contours drawings.The time duration of the one step under the foot is 0.667(second),and the pressures in the seven areas above mention in walking are(183.3±47,161±36,257.2±51,199.2±48,131.8±25,120.4±19 and 204±62)kPa,and in standing and it's percent in whole pressure are 161 kPa (46.68%),118.1(34.24%),14(4.06%),9(2.61%),5(1.45%),18(5.22%) and 19.8(5.74%),And the line of the on the foot plantar colour drawing in walking ever was measured and analysed. Conclusion:An important significance of the results and system were found for diagnosis,treatment,surgical designed and outcome evaluation distribution of the foot disorders.
