无症状扁平足与正常足的足底压力和足弓形态对比研究

目的　通过与正常足青年女性对比分析得出无症状扁平足足底压力和足弓形态的特征。 方法　利用Zebris足底压力测量仪对正常足组（12例）和扁平足组（12例）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。 结果 双足直立时，扁平足组与正常足组的足底压力差异无显著意义（P>0.05）；单足直立时，扁平足组的前足负重比例增大；步行时，扁平足组与正常足组足底压力中心运动轨迹有明显区别。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（P<0.05），而且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（P<0.05）。 结论 无症状扁平足单足直立和行走状态的足底压力和足弓形态与正常足相比有明显区别，为评价、诊断和预防无症状扁平足提供定量化数据。

The asymptomatic flatfoot and normal foot of the young female:the relationship of plantar pressure and plantar arch form

Objective To explore anatomic difference of the asymptomatic flatfoot and normal foot of the young female,and characterize the relationship of plantar pressure and plantar arch form.Methods Using Zebris-system,the static and dynamic plantar pressures of normal feet(twelve cases) and flat feet(twelve cases) were measured,as well,the lateral X-ray projection of the two groups under the weight bearing and non-weight bearing conditions were used to test the plantar arch shape,followed by the statistical analysi...
