Abstract:
BACKGROUND:Human plantar pressure can reflect the health status of the lower limbs and even the whole body,which is an important basis for gait analysis,and body mass index is an important influencing factor. OBJECTIVE:To investigate the effect of body mass index on plantar pressure. METHODS:Twenty young college students from Xuzhou Medical University,including 10 males and 10 females aged 19-21 years,were selected as test subjects and divided into three groups according to the body mass index value:overweight group(body mass index>25 kg/m2,n=3),lean group(body mass index<18 kg/m2,n=4),and normal group(body mass index 18-25 kg/m2,n=13).A natural walking gait test was carried out on the three groups of subjects with a Zebris pressure distribution measurement plate to obtain the complete gait cycle parameters.The time proportion of support time phase,peak pressure,time to peak force,peak force and impulse volume were analyzed and the correlation between each parameter and the body mass index was analyzed by Person analysis. RESULTS AND CONCLUSION:(1)Compared with the other two groups,the time proportion of support time phase of subjects in the overweight group was relatively small,while the time proportion in the foot heel contact period and forefoot extension period was relatively large.There was a positive correlation of the time proportion of the foot heel contact period and forefoot extension period with body mass index,while there was a negative correlation between the time proportion of the arch support period and body mass index.(2)The peak pressure of the left arch and palm of the foot of the subjects of the overweight group was higher than that of the normal group,and the peak pressure of the left and right palm of the foot of the lean group was lower than that of the normal group.The peak pressure was positively correlated with the body mass index during the foot heel contact period.There was a significant positive correlation between the peak pressure of the left foot and body mass index during the arch support period as well as the peak pressure of both feet and body mass index during the forefoot extension period.(3)Plantar peak force time in the order of the gait cycle in increasing order:heel
