Abstract:
BACKGROUND:Body mass is a critical factor affecting plantar pressure,and the systematic study on plantar pressure with different body mass has not been reported.OBJECTIVE:To measure the plantar pressure of normal people with different body weight,so as to provide reference for the application of plantar pressure.METHODS:Totally 80 healthy people with different body weight were enrolled,and the dynamic plantar pressure was measured by the Footscan 2 meter flat foot pressure distribution system (RSscan,Belgium).The participants were divided into four groups (n=20 per group) according to the classification criteria for prevention and control of overweight and obesity in Chinese adults,such as underweight,normal weight,overweight group,and obesity groups,and a comparative analysis was conducted.RESULTS AND CONCLUSION:(1) The peak pressure and impulse of each region of the foot were significantly increased with body mass index increasing (P ＜ 0.05).Compared with the normal weight people,the pressure of the part foot area of the overweight subjects and each part foot area of the obese subjects were significantly increased (P ＜ 0.05).(2) The percentage of the medial plantar contact area accounting the total contact area of the foot was significantly increased with body mass index increasing (P ＜ 0.01);the percentage in the obese group was significantly higher than that in the normal group (P ＜ 0.05).(3) These results show that the plantar pressure and impulse are increased in overweight and obese subjects due to weight gain,and foot will appear with pathological changes with time going.Obese people suffer from arch drop due to weight gain,and increase in contact area of midfoot,which are easy to cause flatfoot.Overweight especially obese,should pay attention to control weight,do appropriate exercise,wear suitable shoes,protect the foot,further to prevent the occurrence of foot injury and flatfoot.
