【摘要】：目的了解小学生背负不同载荷书包时对身体、姿势及足底压力的影响,探讨大载荷书包对学生生长发育的危害。方法运用比利时Footscan insole足底压力测试系统和SONY-HDR-CX390摄像机对16名10岁男性小学生进行不同载荷(相等于其体重5%,10%,15%,20%的书包)书包下足底压力测试和身体姿势拍摄,而后采用Footscan 7.0软件和Adobe photoshop CS5图像处理软件进行分析。结果学生未背书包以及书包重量分别为体重的5%,10%,15%,20%时,行走时身体前倾角度分别为(2.48±0.64)°,(2.91±0.57)°,(3.52±0.55)°,(4.42±0.61)°,(5.04±0.57)°;各载荷情况下与不背书包时前倾角比较,差异均有统计学意义(t值分别为-8.337,-25.165,-36.838,-66.168,P值均0.01)。随载荷量的增加,学生左、右足各区域峰值压强也增加,但第1趾骨和第1,2,3跖骨4区域峰值压强增加幅度较大,足跟内、外侧和第4、5跖骨区域增幅相对较小;各载荷情况与不背书包各区域峰值压强比较,差异大多有统计学意义(P值均0.05)。结论随着学生背负重量的增加,足底压力增大,并可能导致跖骨前横弓下降,不利于学生足弓发育。
[Abstract]:Objective To investigate the effects of different loads on the body , posture and plantar pressure of pupils with different loads , and to explore the harm to the growth and development of students with large loads . The results showed that the body anteversion angles were ( 2.48 卤 0.64 ) 掳 , ( 3.52 卤 0.55 ) 掳 , ( 4.42 卤 0.61 ) 掳 , ( 5.04 卤 0.57 ) 掳 , respectively . The results showed that the front rake angle of the students was ( 2.48 卤 0.64 ) 掳 , ( 4.42 卤 0.61 ) 掳 , ( 5.04 卤 0.57 ) 掳 , respectively . The difference was statistically significant ( t = - 8.337 , - 25.165 , - 36.838 , - 66.168 , P - value 0.01 ) . The peak pressure in the left and right foot of the students increased with the increase of the load , but the peak pressure in the first and the second , third metatarsal bones increased significantly . The difference of the peak pressure in the heel , the lateral and the fourth and fifth metatarsal regions was relatively small .
