摘　　要：目的应用足底压力成像技术,建立足底压力动态图像分析系统。方法设计制作玻璃全反射足底压力成像装置,实验拟合压力图像灰度与压力函数关系,采用视频图象计算机处理分析的方式,动态采集、分析一个步态周期全过程的足底压力分布及变化规律。结果在骨科足趾游离移植术供趾足功能改变、先天性马蹄内翻足早期肌力平衡手术远期疗效研究、三关节融合术治疗小儿麻痹的后遗马蹄内翻足手术效果评定、先天性髋关节脱位和拇外翻的动态足底压力分布等分析应用中,取得对手术及治疗具指导价值的结果。结论该系统简便易行,灵敏度高,对临床不同年龄、不同腿足畸形具有广泛的适应性。Objective We devised a sole stress imaging apparatus by using direct visualization techniques, establishment of a computer video image processing system for measurement of stress distribution in the sole. Methods Developed an imaging apparatus for measurement of pressure under the foot by means of planter pressure direct imaging technique, and conducted experiments to determine the functional relationship between the images and plantar pressures.With use of a computer video image processing system,we collected values of dynamic measurement and analyzed the distribution of the pressure and its changes during the entire process of a gait cycle. Results We have used the system in assessment of the changes in function of the donor foot after 2nd toe to hand transfer,for evaluation of long term results of surgically treated clubfeet by achieving dynamic balance at an early stage, as well as in analysis of dynamic distribution of the plantar pressure following correction by triple arthrodesis of polio derived equinovarus,correction of unilatersl congenital hip dislocation of the, and hallux valgus,providing a valuable guidance for formulating surgical strategy and treatment plan. Conclusion This system is applicable to subjects of different age with a wide range of foot length, and to patiens with a spectrum of injuries and affections of foot and let.
