    摘要 目的 比较三踝骨折术后患者不同步行状态时患侧和健侧足底压力特征,并与健康受试者进行对比。方法 对12例三踝骨折术后恢复期患者和23例健康受试者不同步行状态的足底压力特征进行测试,包括足底10个区域峰值压强、接触面积、接触时间百分比。结果(1)患侧与健侧对比,平地步行的患侧第3-5趾骨区域峰值压强小于健侧,患侧中足区域接触面积小于健侧;内翻斜面时患侧第3-5趾骨区域峰值压强、接触面积小于健侧;外翻斜面时患侧第3-5趾骨区域峰值压强、接触面积、接触时间百分比小于健侧,后足区域峰值压强显著大于健侧。(2)患者与健康受试者对比,在三种步行状态时,患者第2跖骨、第3跖骨、第2趾骨、第3-5趾骨区域的峰值压强均小于正常者,患者第1趾骨、第2趾骨、第3-5趾骨区域的接触面积均小于正常者,患者第2趾骨、第3-5趾骨接触时间百分比小于正常者,中足、后足的接触时间百分比大于正常者。结论 三踝骨折术后患者双侧足底压力特征存在不对称性。与正常者对比,患者在步行支撑相的足底压力异常。患者在外翻斜面运动控制能力、稳定性较正常者有所下降。外翻斜面的足底压力测试能够用于评估患者踝功能。

    Abstract:

    Abstract: Objective To analysis the plantar pressure features of the injured and healthy sides at different stress positions after the Trimalleolar fracture surgery, and compare these characteristics with healthy subjects. Methods Twelve Trimalleolar fracture patients and twenty-three healthy subjects were recruited. Each subject was tested for plantar pressure at different stress positions. The evaluation indices were peak pressure, contact area and contact time percentage. Results (1) In neutral position, the peak pressure of the 3-5th toe in the affected foot was smaller than that in the healthy side; in the inversion position, the peak pressure and contact area of the 3-5th toe area were smaller than those in the healthy side; in the eversion position, the peak pressure, contact area and contact time of the 3-5th toe were smaller than those in the healthy side, and the peak pressure of the hindfoot area was larger than that in the healthy side. (2) In the three position, the peak pressures of the second and third metatarsus bones , the second toe, the 3-5th toe, the contact area of the 1-5th toe and the contact time percent of the second toe, the 3-5th toe area were all smaller than those of healthy subjects, the contact time of the hindfoot and mid-foot area were all smaller than those of healthy subjects. Conclusions The plantar pressure characteristics of Trimalleolar fracture patients are asymmetrical. Compared with healthy subjects, the plantar pressure features of patients are abnormal. Compared with healthy subjects, the motor control ability and stability of patients at eversion stress positions are decreased. The plantar pressure characteristics at ankle eversion could be used to evaluate ankle joint function.
