| 摘 要： | 通过分析脑力、体力劳动者自然行走过程中峰力值（maxforce，MF）、达峰力值时间（time to max force）、冲量（impulse）等参数特征，探讨职业对足底压力分布的影响。采用比利时Footscan USB2平板式足底压测试系统对50名普通健康脑力劳动者和63名普通健康体力劳动者进行自然行走过程中动态足底压力测试。结果显示：脑力、体力劳动者左脚Toel、Toe2-5、Heel Lateral区域平均峰值（MF）存在显著性差异，右脚Mid foot、Meta5区域MF差异存在非常显著性（P〈0．01），左、右双足平均峰力值（MF）最大值均出现在足跟内侧（Heel Medial）。脑力、体力劳动者足底各区域达峰力值的时间（TMF），左右双足差异均存在非常显著性（P〈0．01）。脑力劳动者与体力劳动者行走过程中左足在Toel、Toe2-5、Meta1、Heel Medial、Heel Lateral区域的冲量（Impulse，IP），体力劳动者明显大于脑力劳动者且具有显著性差异〈0．01），体力劳动者与脑力劳动者的足底MF与足弓接触面积及足角度存在不同程度的相关。结果说明：脑力劳动者与体力劳动者行走过程中左右双足的平均峰力值、接触面积、冲量等参数都存在不同程度的差异，可能与长期从事的职业不同有关，建议经常进行体育锻炼或定制矫形鞋垫，可以缓解足底压力高压区的过度集中，不断维护足健康水平。

| Abstract: | By analyzing characteristics of such parameters as Peak Force(PF),Time to Peak Force(TPF) and Im-pulse of brain and physical workers during natural walking,the authors probed into the effects of occupations on the distribution of pressure of the foot sole.By using flat panel type FOOTSCAN USB2 foot sole pressure test system made in Belgium,the authors performed a dynamic foot sole pressure test on 50 ordinary healthy brain workers and 63 ordinary healthy physical workers during natural walking,and revealed the following findings: between brain and physical workers,there is a significant difference in the average PF of Toe1,Toe2~5 and Heel Lateral areas of the left foot,there is a very significant difference(P<0.01) in PF of Mid Foot and Mata5 areas of the right foot,and the maximum value of the average PK of the left and right feet occurs at Heel Medial;there is a very significant differ-ence(P<0.01) in TPF in various areas of the foot sole of the left and right feet between brain and physical workers;during walking,the Impulse of Toe1,Toe2~5,Meta1,Heel Medial and Heel Lateral areas of the left foot of physical workers is significantly greater than the same of brain workers(P<0.01);PF of the foot sole of physical and brain workers is correlative with instep contacting area and foot angle to different extents.The said findings indicate that there is a difference to different extents in such parameters as average PF,Contacting Area and Impulse of the left and right feet between brain and physical workers,which might relates to the difference of occupations they engage in for a long period of time.The authors suggested that doing physical exercises on a regular basis or wearing a custom made orthopedic insole can release over concentration of foot sole pressure in high pressure areas,and con-stantly maintain the level of foot health. |
