【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。结果与结伦:(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(P0.05);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(P0.05);而足跟外侧区域的参数明显低于正常站立时(P0.05);(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(P0.05);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(P0.05);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(P0.05);(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: technological advances in smartphones have not only brought a lot of convenience, but also made many people too dependent on apps, especially when young people often stand or walk while staring at the phone. This state may affect the static balance and plantar pressure gait characteristics of young people. Objective: to observe the effects of male youth staring at mobile phone on static balance, plantar pressure and gait characteristics during standing or walking. Methods: 20 healthy young men were selected as subjects for the study of gait or lower extremity joint damage caused by staring at mobile phone during prolonged standing or walking. The plantar pressure was measured by Loran (Italy) plantar pressure distribution system during normal standing and walking. After 20 min rest, The subjects were asked to stare at their cell phones for 10 minutes, and then repeated the tests according to the above test procedure. The data were obtained by the system software. The relative indexes in two states were compared and analyzed. The results were compared with the velocity of fluctuation of the track of the center of gravity of the plantar during the male youth gazing at the mobile phone for 20 s. The displacement and locus area were obviously larger than that of P0.05 when standing normally, and the contact area of the first metatarsal bone and the second metatarsal bone in the plantar region, The peak pressure and average pressure were also significantly higher than that of normal standing, while the parameters of lateral calcaneal area were significantly lower than those of normal standing (P0.05)) the walking step and speed of male youth staring at mobile phone walking were obviously lower than that of normal walking. The angle between the support time of the feet and the walking angle of the left and right feet is obviously larger than that of the P0.05 in normal walking. The fourth metatarsal bone in the plantar region, the fourth metatarsal bone in the plantar region, The contact area, peak pressure and average pressure of the fifth metatarsal bone and the lateral heel of the foot were significantly higher than those of the normal walking group (P0.05 / 3). The results showed that the body weight of the male youth gazing at the mobile phone standing was unstable and leaning forward compared with the normal standing. The gait characteristics of normal walking have been changed by male youth gazing at mobile phone walking, mainly reflected in the longer support time, shorter step length, slower step speed, greater walking angle and greater lateral pressure on the foot sole.
