摘要
目的:研究大学生在静态站立和步态行走过程中凝视手机对步态特征、足底压力和下肢生理结构的影响。方法:运用文献资料法、实验法、数理统计法,利用MedTrack足底压力分布板测试系统测试34名大学生凝视手机站立和行走时的足底压力。结果:(1)静态站立中,凝视手机时足底重心轨迹线和轨迹面积显著大于正常站立。(2)动态行走过程中,凝视手机时行每分钟步数明显减缓;左右脚行走触地时间和双脚支撑的时间明显增加;其左侧足底M2、M5和HM以及右侧足底T2~5、M2、M4的峰值压力,以及左右侧足底M5、LH的接触面积明显高于正常行走时。结论:凝视手机行走和站立时的姿态会影响足底压力的分布改变其步态特征,会加大身体重心在支撑面的晃动,使身体保持正常形态所需肌肉活动量增多,出现了肌肉的代偿现象,容易产生损伤和疲劳,在有突发事件时容易跌倒且损伤的风险增大。
The objective of this paper is to investigate the effects of mobile phone gaze on gait characteristics,plantar pressure,and lower limb physiological structure in college students during static standing and gait walking.Methods:Using the methods of literature review,experimentation,and mathematical statistics,the MedTrack plantar pressure distribution board test system was used to test the plantar pressure of 34 college students while standing and walking with and without staring at the mobile phone.Results:(a)In static standing,the trajectory line and the trajectory area of the plantar center of gravity when staring at the phone were significantly larger than those in normal standing.(b)During dynamic walking,the average walking speed and steps per minute decreased significantly while staring at the phone.The time of walking with left and right feet and the time of supporting with both feet increased significantly.The peak pressure of M2,M5 and HM on the left foot and T2-5,M2 and M4 on the right foot,and the contact area of M5 and LH on the left and right foot were significantly higher than those in normal walking.Conclusion:The posture of walking and standing while staring at the mobile phone can affect the distribution of plantar pressure and change the gait characteristics,increase the sway of the body's center of gravity on the support surface,increase the amount of muscle activity required to maintain the normal shape of the body,and cause muscle compensation phenomenon,which is prone to injury and fatigue.
