文题释义:
正常站立或行走试验:
是一种自然站立或行走的状态,以个人习惯为标准,并在指定的测试步道进行适应    5 min左右,并咨询是否适应步道。
凝视手机站立或行走试验:在正常站立或行走的基础之上,需要志愿者专注于盯着手机进行正常站立或行走试验,并客观的证明长时间站立或行走状态下凝视手机对静态平衡能力、步态特征及下肢关节的影响情况。

 

摘要
背景:
智能手机的科技进步不仅仅带给人们很多便利,同时也使很多人过于依赖应用手机,尤其是青年常常站立或行走的同时凝视手机,这种状态可能会影响青年静态站立平衡以及足底压力步态特征。
目的:观察男性青年在站立或行走过程中凝视于手机对静态平衡、足底压力和步态特征的影响,以期预警长时间站立或行走时凝视手机对人体步态或下肢关节的损害。
方法:选择20名健康男性青年作为测试对象,采用意大利LorAn(型号:MPS)足底压力分布测试系统测试受试者正常站立和行走时的足底压力,休息20 min后,再让该受试者凝视手机10 min,之后再按上述测试流程重复测试一遍。经系统软件得出数据,对2种状态下的相关指标进行比较分析。
结果与结论:①男性青年凝视于手机站立20 s过程中,足底重心轨迹线的波动速度、位移以及轨迹面积明显大于正常站立时(P < 0.05);并且足底区域中的第1跖骨和第2跖骨区域的接触面积、压力峰值以及平均压强也明显大于正常站立时(P < 0.05);而足跟外侧区域的参数明显低于正常站立时(P < 0.05);②男性青年凝视于手机行走过程中行走步长和步速明显小于正常行走时(P < 0.05);双脚支撑的时间和左右脚行走的夹角明显大于正常行走时(P < 0.05);足底区域中的第4跖骨、第5跖骨和足跟外侧的接触面积、压力峰值以及平均压强大小明显大于正常行走时(P < 0.05);③结果提示,男性青年凝视于手机站立的身体重心比正常站立时不稳定并偏向前;男性青年凝视于手机行走已改变了正常行走的步态特征,主要体现于支撑时间变长、步长变短、步速变慢、步行角度增大以及足底外侧压力增大。

Abstract:

BACKGROUND: Smartphones are a double-edged sword, which not only bring convenience, but also result in excessive reliance. Especially the youth often gaze at their phones when standing or walking, which may affect their static standing balance and plantar pressure gait characteristics.
OBJECTIVE: To investigate the influence of staring at mobile phones when standing or walking on the static balance, plantar pressure and gait characteristics in young men, thus informing its negative effect on gait characteristics and lower limb joints. 
METHODS: Twenty health young men were selected, the plantar pressure when normal standing and walking was measured using Loran plantar pressure analysis system (NO. MPS, Italy). After 20 minutes of rest, the same measurement was performed in all participants staring at mobile for 10 minutes during standing or walking. The relative indexes were compared between two conditions after data collection.
RESULTS AND CONCLUSION: When young men staring at mobile phone for 20 seconds during standing, the fluctuation speed, displacement and track area were significantly larger than those during normal standing (P < 0.05); moreover, the contact area, pressure peak and average pressure of the first and second metatarsus in plantar area were significantly larger than those during normal standing (P < 0.05), while the parameters of heel lateral area were significantly lower than those during normal standing (P < 0.05). The stride and speed when staring at mobile phone during walking were significantly smaller than those during normal walking (P < 0.05); the support time of two feet and angle between feet were significantly larger than those during normal walking; the contact area, pressure peak and average pressure of the 4th and 5th metatarsus in plantar area and heel lateral area were significantly larger than those during normal walking. These results suggest that the gravity is less stable and more anterior when young men staring at mobile phone during standing than during normal standing. Staring at mobile phone during walking can alter the gait characteristics, resulting in longer support time, shorter stride, slower step speed, larger walking angle and higher lateral plantar pressure.
