【摘要】：运用足底压力测试与影像学X线测量结合的足踝数字化无损测评系统,对比分析无症状扁平足者与正常足者在足底压力和足弓形态上的生物力学差异。受试为青年学生,其中正常足者12人(男女各6人,左右足共24只,其中左足12只,右足12只),无症状扁平足者12人(男女各6人,左右足共24只,其中左足12只,右足12只)。利用Zebris足底压力测量仪对正常足组和无症状扁平足组进行直立状态和行走状态下的足底压力测试,并拍摄其负重位和非负重位的侧位X线片进行足弓形态测量,测量数据进行统计学分析,从而对比得出无症状扁平足与正常足足弓和足底压力方面的生物力学差异。结果表明:双足直立时,无症状扁平足组与正常足组的足底压力差异无显著意义(P0.05);单足直立时,无症状扁平足组的足前负重比例增大;步行时,无症状扁平足组与正常足组足底压力的峰值相比差异显著(P0.05)。无症状扁平足组负重位与非负重位的足弓形态各参数有显著差异(P0.05),而且无症状扁平足组负重位与正常足组负重位的足弓形态有显著差异(P0.05)。非负重状态和双足直立状态下,无症状扁平足表现出一定的隐匿性。单足直立和行走状态下,无症状扁平足的足底压力和足弓形态与正常足相比有明显差异。应用FA-DNTS测量评价足踝生物力学性能,方法简单,实用,易于推广。
[Abstract]:The digital nondestructive evaluation system of ankle was used to compare and analyze the biomechanical differences between the asymptomatic flat foot and the normal foot on the plantar pressure and the shape of the arch by using the digital nondestructive evaluation system based on foot pressure test and X-ray radiography. The subjects were young students. Among them, there were 12 normal feet (6 male and 6 male, 24 left foot), 12 left foot, 12 right foot and 12 asymptomatic flat foot (6 male and 6 male, 24 left foot, including 12 left foot). The plantar pressure of normal foot group and asymptomatic flat foot group were measured by Zebris plantar pressure measuring instrument in 12 right foot. The plantar pressure of normal foot group and asymptomatic flat foot group were measured under standing and walking conditions, and the lateral radiographs of weight bearing position and non-weight bearing position were taken to measure the shape of foot arch. The biomechanical differences between asymptomatic flat foot and normal foot arch and plantar pressure were obtained by statistical analysis of the measured data. There was no significant difference in plantar pressure between the asymptomatic flat foot group and the normal foot group. There was significant difference in the peak of plantar pressure between the asymptomatic flat foot group and the normal foot group (P 0.05). There were significant differences in the arch shape parameters between the asymptomatic flat foot group and the non-load position group, and there was significant difference between the asymptomatic flat foot group and the normal group. There was a significant difference in the arch shape of the foot in the weight-bearing position of the foot group (P 0.05). The foot pressure and arch shape of the asymptomatic flat foot were significantly different from those of the normal foot under the condition of standing and walking. The method of FA-DNTS measurement to evaluate the biomechanical properties of foot and malleolus was simple. Practical and easy to popularize.
