Variation of Spatiotemporal Parameters in School Children Carrying Different Backpack Loads

Summary

Backpacks (BP) represent the method most used by students to transport external cargo. Previous studies cite that between 4.7% and 38% of children carry daily BP loads greater than 20% of their body mass. The purpose of this study was to analyze spatiotemporal parameters of gait in children using varyingly loaded BPs.

Backpack child's body weight

Children are asked to walk naturally, facing forward, with their hands out of pockets; wearing light, comfortable clothes, with the BP placed correctly. As the children start walking, the researchers select the foot of the first step inside the bars, in the Optogait software. After being instructed to 'walk slowly at a comfortable speed', the children walk from a point two metres in front of the bar and stop at a point two metres behind the last bar, to minimize effects of acceleration and deceleration . A three-minute interval occurs between individual assessments to transmit the data, as well as to prepare for the next assessment. Only steps in the sensor areas are included in the analysis. Recording six to eight strides is reported as sufficient to obtain representative data for unimpaired adults. Subsequently, five experimental conditions are measured: without BP, BP loads of 5%, 10%, 15%, and 20% of body weight. The order of these loaded conditions are random.
