A Comparative Study On The Walking Gait Of The Ice Pavement And The Common Road

Based on the biomechanical study of healthy elderly snow walking gait,in order to investigate the biomechanical characteristics of the elderly mechanism of snow and ice road,to prevent the elderly fall,is of great significance to develop effective intervention measures.Study on the selection of Quintic motion capture and analysis system and Footscan insole system to obtain kinematic parameters and pressure distribution of plantar pressure parameters in elderly patients with normal pavement and snow on the road,and carries on the comparative analysis,the research conclusions are as follows:5.1 when the elderly walk on the ice and snow road,the time of a gait cycle is reduced,the supporting period is relatively increased,and the swing period is greatly reduced.5.2 on the ice and snow road walking step value decreased significantly,the value of the step width decreased significantly(P < 0.05),the speed of walking was greatly reduced.5.3 walk on the ice road trunk angle range significantly lower(P < 0.01),compared to the range of motion of hip and normal walking slightly;range of knee joint and ankle joint activities range than normal walking decreased more significantly;step angle values were significantly reduced,suggesting that the ice walking step,walking pattern steady posture.5.4 the changes of the plantar pressure center on the X axis and the Y axis on the ice and snow road were reduced,and the center of gravity of the foot pressure was more concentrated in the middle of the human foot5.5,the ice and snow road walking heel peak pressure is low,and the pressure at T1 foot thumb on the part of the ice,walking very significantly higher than normal walking(P<0.05);T1,T2-T5,M4 parts of the impulse value was significantly higher than that of ordinary walking.
