RESUMEN
BACKGROUND: Children with cerebral palsy (CP) often demonstrate postural control difficulties. Orthotic management may assist in improving postural control in these children. OBJECTIVE: The purpose of this investigation was to examine the influence of floor reaction ankle foot orthosis (FRAFO) on postural flexion called the crouch position in children with CP. STUDY DESIGN: Quasi-experimental. METHODS: Eight children with spastic diplegic CP and eight matched typically developing children participated in this study. Postural control of children with CP was assessed in a static standing position on a force platform with/without a FRAFO. The parameters used were centre of pressure (CoP) measures, calculated from force platform signals including the standard deviation (SD) of excursion; phase plate portrait and SD of velocity in anteroposterior (AP) and mediolateral (ML) directions. RESULTS: The maximum knee extension was statistically significant in children with CP when barefoot compared to wearing braced footwear (p < 0.05, t = 10.01). AP and ML displacement, AP velocity and AP phase plate portrait of CoP were not statistically significant between children with CP with/without a FRAFO (p < 0.05). CONCLUSION: FRAFO can improve the alignment of the knee, but may not be helpful in improving postural control in children with CP in a short time period.
