Background:According to literature, little is known regarding the effects of orthotic management of flatfoot on kinetics of vertical jump.Objectives:To compare the kinetic and temporal events of two-legged vertical jumping take-off from a force plate for heading a ball in normal and flexible flatfoot subjects with and without insole.Study design:A functional based interventional controlled study.Methods:Random sampling method was employed to draw a control group of 15 normal foot subjects to a group of 15 flatfoot subjects. A force platform was used to record kinetics of two-legged vertical jump shots.Results:Results indicate that insole did not lead to a significant effect on kinetics regarding anterior-posterior and mediolateral directions (p > 0.05). Results of kinetics related… Continue reading →
