摘　　要：探讨高原世居藏族与移居汉族健康青年足底压力分布规律,比较两个民族青年人群足底压力特征差异。为构建高原人群步态数据库提供基础数据。运用意大利MPS足底压力测试系统对经过筛选的西藏大学在校世居与移居高原健康青年160人进行双足足底压力测试,对获取的数据进行统计学分析。结果表明:(1)站立时男性接触面积、女性峰值压强、平均压强、足弓指数在民族间存在差异(P<0.05);行走时女性接触面积和足轴角在民族间存在差异(P<0.05)。(2)男性第1趾(T1)、第2~5趾(T2~5)、第5跖骨(M5)区域的接触面积、T1、T2~5、第2跖骨(M2)区域的压力峰值、足中部(MF)区域的峰值压强以及T1、T2~5、第1跖骨(M1)、M2、第3跖骨(M3)、第4跖骨(M4)、M5区域的冲量在民族间存在差异(P<0.05);女性T1、T2~5、M4、M5、足跟内侧(MH)、足跟外侧(LH)区域的接触面积,T1、T2~5、M2区域的压力峰值,T1、M1、M4区域的峰值压强,T1、T2~5、M4区域的平均压强,以及T1、T2~5、M1、M2、M5、MH区域的冲量在民族间存在差异(P<0.05)。(3)足弓指数、压力峰值(T1、T2~5、M2)和冲量(T1、T2~5、M1、M2、M4、M5)与民族呈现显著的相关性。世居藏族与移居汉族青年足底压力测试指标存在显著差异,且足底各区域参数的分布规律不同。两个民族的健康青年足底压力分布具有其独特性。This paper explored the distribution pattern of plantar pressure in healthy young people of Tibetan and Han nationality in the plateau and compared the differences in the plantar pressure characteristics between the two nationality groups,which provides basic data for constructing a gait database for plateau populations.Using the Italian MPS plantar pressure testing system,plantar pressure tests were conducted on 160 selected healthy young people residing and migrating to high altitude in Tibet University,and the obtained data were statistically analyzed.The results are as follow:(1)there are differences in male contact area,female peak pressure,average pressure,and arch index between nationality groups when standing(P<0.05),and there are differences in female contact area and foot axis angle between nationality groups during walking(P<0.05).(2)There are differences in male contact area(Toe1,Toe2-5,Meta5),peak force(T1,T2-5,Meta2),peak pressure(Mid Foot)and impulse(T1,T2-5,Meta1,M2,Meta3,Meta4,M5)among nationality groups(P<0.05),and there are differences in female contact area(T1,T2-5,M4,M5,Medial Heel,Lateral Heel),peak force(T1,T2-5,M2),peak pressure(T1,M1,M4),average pressure(T1,T2-5,M4)and impulse(T1,T2-5,M1,M2,M5,MH)among nationality groups(P<0.05).(3)Arch index,peak force(T1,T2-5,M2),and impulse(T1,T2-5,M1,M2,M4,M5)are significantly correlated with nationality.There is significant difference in plantar pressure test indicators between Tibetan and Han nationality,and the distribution pattern of plantar parameters varies among different regions.The unique characteristics were found in the plantar pressure distribution of healthy young people from two nationality groups.
