摘　　要：目的测量业余马拉松运动员的足底压力,分析后踝撞击综合征与足底压力分布的相关性,从而为业余马拉松爱好者提供有益指导。方法纳入35例业余马拉松运动员,其中18例MRI显示双足正常,17例MRI显示单足或双足存在后踝撞击综合征。采用芯康Footscan平板式足底压力测试系统对业余马拉松运动员进行测试,静态站立测试时,分为正常组、单足后踝撞击组、双足后踝撞击组。裸足行走时,分为正常组、双足后踝撞击组、单足后踝撞击组、单足代偿组。静态站立测试双足X轴重心偏移值,裸足行走时测量第1跖骨区域峰值压强和足弓内侧步态周期停止时间。结果静态站立测试时,双足后踝撞击组X轴重心偏移值明显小于正常组,差异有统计学意义(P<0.05);单足后踝撞击组与双足后踝撞击组、正常组X轴重心偏移值差异无统计学意义(P>0.05)。裸足行走测试时,组间第1跖骨区域峰值压强差异有统计学意义(P<0.05),单足代偿组峰值压强明显大于正常组、单足后踝撞击组及双足后踝撞击组。裸足行走测试时,单足后踝撞击组足弓内侧步态周期停止时间明显短于单足代偿组、双足后踝撞击组,差异有统计学意义(P<0.05)。结论后踝撞击综合征对足底压力的分布存在影响,进而可能加剧足踝关节损伤。足底压力分布特征分析有助于了解业余马拉松跑步运动员的足踝关节损伤情况,帮助其规范训练并指导踝关节保护,从而降低踝关节损伤风险。Objective To measure plantar pressures in amateur marathon runners and analyze the correlation between posteri-or ankle impingement syndrome and the distribution of plantar pressures,so as to provide useful guidance for amateur marathon runners.Methods Thirty-five amateur marathon runners were included,of whom 18 had normal feet on MRI and 17 had pos-terior ankle impingement syndrome in one or both feet on MRI.The amateur marathon runners were tested with the CoreCon Footscan Flatbed Plantar Pressure Test System.During the static standing test,they were divided into normal group,monopedal posterior ankle impingement group and bipedal posterior ankle impingement group.When walking barefoot,it was divided into normal group,bipedal posterior ankle impingement group,monopedal posterior ankle impingement group,and monopedal com-pensation group.Bipedal X-axis center of gravity offset values were tested in static standing,and peak pressure in the lst meta-tarsal region and the stopping time of the medial arch gait cycle were measured during barefoot walking.Results During the static standing test,the X-axis center of gravity offset values of the bipedal posterior ankle impingement group were significant-ly smaller than those of the normal group,and the difference was statistically significant(P<0.05);whereas the differences in the X-axis center of gravity offset values between the monopedal posterior ankle impingement group and the bipedal posterior ankle impingement group,the monopedal posterior ankle impingement group and the normal foot group,were not statistically significant(P>0.05).During the barefoot walking test,the difference in peak pressure in the lst metatarsal region between the groups was statistically significant(P<0.05),and the pressure in the monopedal compensatory group was significantly greater than that in the normal group,monopedal posterior ankle impingement group,and bipedal posterior ankle impingement group,and the difference was statistically significant(P<0.05).During the barefoot walking test,
