Análise cinemática do andar de crianças transportando mochilas / Kinematics variables during children`s gaint with knapsack

RESUMO

The obiective of this study was to describe the behavior of kinematics variables during children's gait with and without knapsack. The sample was canstituted af four female and two male school children aged between eight and nine. Two cameras with frequency af 60 Hz were used for data callection and Peak Motus system was used in data analysis. No differences in the spatial and temporal variableswere observed when subjects walked with and withaut backpack. These values were in accordance with the literature. Significant differences in velocity, cadence, trunk inclination and hip angle were found between gait with and without backpack. The behavior of hip angle was in accordance with the literature, hawever with greater values in gait using knapsack. This can be consequence of a compensatory posture af the trunk. Otherwise, the pelvis and knee angles did not present significant difference between gait with and without backpack
