There is limited evidence assessing the effect of the Ankle Foot Orthosis (AFO) on gait improvements in diplegic cerebral palsy. In particular, the effect of the AFO on vertical forces during gait has not been reported. Appropriate vertical ground reaction forces are crucial in enabling children with CP to walk efficiently. This study investigated the effect of AFO application on the vertical forces in gait, particularly the second vertical peak in force (FZ2) in late stance. The force data was compared with the barefoot walk. A retrospective analysis of nineteen children (8M,11F) who met inclusion criteria of a diagnosis of spastic diplegic CP, ability to walk independently barefoot and also using bilateral rigid AFOs were included. Gait data were acquired using the Vicon-Nexus ® motion-capture. Resulting ground reaction force data were recorded. Appropriate statistical methods assessed significance between barefoot and AFO dataIntroduction
