To transport school materials, trolleys have been proposed for children as an
alternative to carrying a backpack. However, there is limited evidence comparing
the adaptations associated with carrying school trolley versus backpack. This study compared the effects of carrying a backpack and pulling a trolley on gait
kinematics in children.
Fifty-three students were evaluated. Children walked at
self-selected speeds across a walkway with no bag (control), carrying a backpack
with the 15% of childs body weight (%BW) and pulling a trolley with the same
load. Spatiotemporal gait parameters and 3D kinematics of lower extremities and
thorax were computed. No significant differences were obtained in spatiotemporal
parameters between pulling a trolley and control. Carrying a backpack resulted in
larger kinematics gait alterations than pulling the trolley compared to control.
In conclusion, pulling a school trolley (15%BW) was more similar to not carrying
a bag than carrying a backpack of the same load during level walking.
