Using the Edinburgh Visual Gait Score to Compare Ankle-Foot Orthoses, Sensorimotor Orthoses and Barefoot on Gait Pattern in Children with Cerebral Palsy: A Cross-Sectional Cohort Study
Abstract Background: Gait analysis is one of the important aspects of evaluation in ambulatory children with cerebral palsy (CP). Typically prescribed for children with CP, ankle-foot orthoses (AFOs) improve gait and alignment through providing support and stability to the ankle complex. An alternative and under-researched orthosis being used in this population is the Sensomotoric orthotic (SMotO), which uses a different approach to correct alignment and improve gait. The Edinburgh Visual Gait Score (EVGS) is a valid, robust, reliable and easy-to-use observational gait analysis scale to measure of gait quality in CP. Improvements to gait could then be attributed to intervention, or regression of gait could be attributed to poor intervention or physical changes. Therefore, the aim of this study was to use the EVGS to determine the effect of SMotOs, AFOs and barefoot on gait pattern in children with CP. Methods: This cross-sectional cohort study investigated the differences in gait quality in children with CP between wearing SMotOs and AFOs through using the EVGS. Video imagery was taken when walking barefoot (where appropriate), in SMotOs and in AFOs for at least 5m at a self-directed pace. Individual scores and averages across the population were recorded. Data was analysed through SPSS statistics software (Version 20) and the Microsoft Office Excel 2007. A one-way ANOVA and post hoc Bonferroni were completed to identify significant differences with the alpha level set at p<.05. Results: One-way ANOVA analyses revealed significant differences between total left (p=0.011) and right (p=0.014) scores between SMotO and AFOs. Overall, results demonstrate improved gait in favour of SMotO vs AFO and that there are no significant differences between being barefoot and wearing AFOs. Conclusions: SMotOs are a viable orthotic option to improve gait in children with CP, but due to small yield of participants, a larger scale, blinded study should be performed to further determine results.
