Children with cerebral palsy (CP) present a variety of motor impairments and activity limitations. Plastic ankle-foot orthoses (pl-AFO) are frequently prescribed to improve their gait. However, their use limit forward propulsion generation, which explains why children tend to remove their pl-AFO during recreational activities,including running and jumping. While the benefits of physical activity are proven for these children, there is no data about pl-AFO impact across a range of locomotor activities. Biomechanically optimized dynamic carbon fiber AFOs (c-AFO) are now available and may improve propulsion features in comparison with usual pl-AFOs. The investigators aim to compare the AFO-specific effects (pl-AFO vs c-AFO) on propulsion (during walking, running and jumping), to explore the consequences on social participation, as well as to evaluate the effect on the hemiparetic CP child's perception and adherence of wearing each AFO. In this prospective, multicenter, randomized controlled trial with a crossover design, 38 hemiparetic CP children from 8 to 15 years old will be evaluated with their usual pl-AFO and with a c-AFO. The pragmatic clinical approach of this study is expected to provide data to guide and optimize AFO prescription and use, while enhancing understanding of these devices and their adaptation to the actual physical activity of CP children.
