Comparative Study on Plantar Pressure Distribution Characteristics in Children of Different Ages and Genders
This study selected 100 male and female students aged 7 and 10 from XX Primary School as subjects.Using the Footscan plate system,plantar pressure data were collected during standing and walking.A one-way ANOVA was used to sta-tistically analyze the data to gain an in-depth understanding of the plantar pressure distribution characteristics in children,comparing differences between left and right feet,age differences,and gender differences.Results:During static standing,the children's center of gravity fell in the rearfoot area,generally in the right rearfoot area,with 10-year-olds having better stat-ic center of gravity control than 7-year-olds.In children's dynamic plantar pressure,the forefoot received the greatest impulse,followed by the heel,and the midfoot received the least.The metatarsal area of the forefoot received a larger impulse.From the perspective of maximum pressure,the heel area experienced the greatest force,and the force distribution in the metatarsal area generally showed M3>M2>M5>M1>M4.As age increased,the force in the heel and third metatarsal areas in-creased,with girls showing this more prominently than boys.Children exhibited an unbalanced gait,with significant left-right differences in the midfoot and heel areas.Specifically,the midfoot values of the left foot were greater than those of the right foot,while the heel values were smaller than those of the right foot,with girls showing these differences more prominently.Conclusion:Seven-year-old children transitioned through the heel strike phase faster and had a quicker step frequency com-pared to 10-year-olds.Girls of the same age group had dynamic plantar pressure characteristics closer to adults than boys.
