Multidimensional Effects of Solid and Hinged Ankle-Foot Orthosis in Children With Cerebral Palsy

PURPOSE: To compare the effect of solid (SAFO) and hinged (HAFO) ankle-foot orthoses in children with cerebral palsy spastic diplegia and true equinus and jump gait. METHODS: Participants were 26 children (13 wore SAFO and 13 wore HAFO) aged 4 to 14 years classified as Gross Motor Function Classification System levels I to III. Children were tested on standardized measures of body structure and function, activity, and participation. RESULTS: Children wearing HAFO reached further in standing than those wearing SAFO. Among children who walked without an assistive device, children wearing HAFO had greater stride length and faster velocity. Mean Gross Motor Function Measure and Pediatric Evaluation of Disability Inventory mobility scores did not differ between groups. The cost-to-benefit ratios showed parents preferred HAFO. CONCLUSIONS: Among children with true equinus and jump gait, the effects of HAFO were greater in children who walked without an assistive mobility device.
