Tibial Impact Accelerations in Gait of Primary School Overweight and Obese Children and Normal Weight Children: The Effect of Speed and Visual Biofeedback.

Tibial stress fractures are associated with increased lower extremity loading at initial foot-ground contact, reflected in high peak positive acceleration (8 g) of the tibia in adults. The use of visual biofeedback has been suggested to reduce mean peak positive acceleration of the tibia. There is no reported data on peak positive acceleration of the tibia in children and obese children during walking and running. The aims of this study were 1) To compare overweight and obese children`s mean peak positive acceleration to normal weight children, 2) To determine if the real-time visual feedback effects can reduce mean peak positive acceleration responses in obese children across a range of gait speeds.
