Children require less gait kinematic adaptations to pull a trolley than to carry a backpack. Gait & Posture, 52, 189-193.10.1016/j.gaitpost.2016.11.041https://hdl.handle.net/10433/22369CAS15/00191 FECYT -- FPU13/00162 FECYT -- EST15/00019To 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 child’s 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 signi cant 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.application/pdfenLoadStudentsGaitWheeled backpackjournal articlerestricted access
