The aim of this study was to determine the influence of the schoolbag carriage on pattern changes in plantar pressure during walking among schoolchildren in the first grade. The sample consisted of 127 schoolchildren, 48.8% male (N = 62) and 51.2% female (N = 65), with a mean age of 6.7 (± 0.5) years. The mean schoolbag weight was 4.2 kg (± 0.7), which represented a 16.9% (± 3.9) of the body weight, thus exceeds the upper limit of 15% of the body weight and can affect the posture by a general way. This study has shown a statistically significant influence of the school bag on changes in plantar pressure pattern when walking in relation to walking without the schoolbag. Using a t-test for large dependent samples and by setting statistical significance at p ≤ 0.05, a significant increase was noticed in peak pressure for the forefoot (p = .000; 17.1%), midfoot (p = .000; 5.7%) and the hindfoot (p = .004; 3.9%) as well as in average pressure for the midfoot (p = .005; 6.2%). Also, due to the compensatory mechanisms, while carrying the bag, a statistically significant increase in the contact surface at the forefoot (p = .000; 3.6%) and the midfoot (p =. 000, 8.8%) occurs. Changes in the distribution of pressure between the different parts of the foot are a source of potential foot problems which is why the results of this study have a high applicability in the prevention of foot pathology in the future.

一年级学童行走时书包搬运对足底压力模式变化的影响

这项研究的目的是确定书包支架对一年级学童走路时足底压力模式变化的影响。样本由127名学童组成，男性48.8％（N = 62）和51.2％女性（N = 65），平均年龄为6.7（±0.5）岁。书包的平均重量为4.2千克（±0.7），占体重的16.9％（±3.9），因此超过了体重15％的上限，并且可以通过一般方式影响姿势。这项研究表明，与不带书包走路相比，书包对走路时足底压力模式变化具有统计学上的显着影响。通过对大量依赖样本进行t检验并通过将统计显着性设置为p≤0.05，可以发现前脚的峰值压力显着增加（p = .000； 17。1％），中足（p = .000; 5.7％）和后足（p = .004; 3.9％）以及中足的平均压力（p = .005; 6.2％）。同样，由于具有补偿机制，在携带袋子时，前脚（p = .000； 3.6％）和中脚（p =。000，8.8％）的接触面发生统计上显着的增加。足部不同部位之间压力分布的变化是潜在的足部问题的根源，这就是为什么本研究的结果在将来预防足部病理学方面具有高度适用性的原因。6％）和中足（p =。000，8.8％）发生。足部不同部位之间压力分布的变化是潜在的足部问题的根源，这就是为什么本研究的结果在将来预防足部病理学方面具有高度适用性的原因。6％）和中足（p =。000，8.8％）发生。足部不同部位之间压力分布的变化是潜在的足部问题的根源，这就是为什么本研究的结果在将来预防足部病理学方面具有高度适用性的原因。
