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.
