Comportamento cinemático de membro superior e tronco durante o andar de crianças transportando mochila de rodinhas

Abstract

The main objective of this study was to investigate possible alterations that can occur in the trunk and in the superior members of the schoolchild, during the gait, when it carries wheel backpack. The studied group was composed of seven children, with five male children and two female children, all they were seven years old. For the procedures of the collection of the kinematics data, two cameras had been used with 60 Hz of acquisition frequency. The cameras were located approximately perpendicular between themselves. In a first moment, it subject had been instructed to walk normally, later loading the wheel backpack with a weight corresponding 10% of its corporal weight and later 20% of the same. Statistical differences had been identified in all studied angular variables when it were compared the situation using wheel backpack with non using it. However, statistical differences had not been found when it were confronted the situations carrying a load of 10% with a load of 20% of the corporal weight.
