Quantitative Evaluation of the Effects of Ankle Foot Orthosis on Gait in Children with Cerebral Palsy Using the Gait Profile Score and Gait Variable Scores
Ankle foot orthoses (AFOs) are often used in children with Cerebral Palsy (CP) to facilitate and optimise their impaired gait pattern. The aim of this study was to assess quantitatively the effects of AFOs on gait in CP using a summary measure obtained by Gait Analysis (GA): the Gait Profile Score (GPS) with its Gait Variable Scores (GVSs).
A total of 21 children with CP (hemiplegic group: 11 children; diplegic group: 10 children) were evaluated barefoot and wearing AFOs using GA; GPS with its GVSs were calculated from GA data. The results evidenced that in diplegic children significant improvements when wearing AFOs were observed at pelvic tilt and ankle dorsi-plantarflexion GVS values; no changes were found as for GPS. The plegic side of hemiplegic children improved significantly globally with AFO, as displayed by the reduction of GPS value; in addition, some reductions were observed in terms of pelvic rotation and obliquity, knee flex-extension and ankle dorsi-plantarflexion GVSs. Significant changes appeared at some GVS values of the non-plegic side, too.
Our results showed that, compared with barefoot gait, AFOs enhanced gait strategy in diplegic and hemiplegic children with CP. While GPS, together with GVSs, seems to be a useful method for evaluating immediate effects of AFOs in hemiplegia, in diplegia the improvements are evident only in some GVSs (pelvic tilt and ankle dorsi-plantarflexion) but not in GPS.
