Andersen Children’s Hospital, Odense University Hospital, Odense, Denmark; Department of Paediatrics, Lillebaelt Hospital, Kolding, Denmark; Department of Paediatrics, Hospital of Western Jutland, Esbjerg, Denmark Background: The Cerebral Palsy follow-Up Program (CPUP) is used to ensure consistent examinations of children with cerebral palsy (CP). However, gait function by 3D gait analysis is not evaluated within CPUP. Purpose / Aim of Study: To test the hypothesis that improvements in gait and function following interdisciplinary interventions using 3D gait analysis in the decision-making are superior to those following ‘care as usual’ without gait analysis in young children with CP. Materials and Methods: A pragmatic, single blind, randomised (1:1) controlled trial. Primary outcome was gait function at 52 weeks follow-up evaluated by Gait Deviation Index (GDI) and secondary outcomes were: patient reported outcomes of function, disability and quality of life. Using a minimum clinically important difference of 7.9 (SD 12) GDI points, alpha = 0.05, and 80% power, a total of 60 children were included. Findings / Results: Between-groups change scores were evaluated by a multi- ple regression model. The statistical analysis plan was registered at ClinicalTrails. gov (NCT02160457) and a protocol paper was published ahead. Sixty children (median age 6y11m) with CP at Gross Motor Function Classification System levels I (n = 42) and II (n = 18), were randomised to interventions with or without gait analysis. The categories of interventions were dominated by non- surgical interventions that were applied in 36 to 86% of the participants. No significant or clinically relevant between- group differences in change scores of the primary or secondary outcomes were found. Conclusions: Interdisciplinary interventions using gait analysis did not improve gait or function in the present sample of relatively young and well-functioning children with CP. However, 3D gait analysis may still be relevant in children with higher levels of disability or if a functional diagnosis is needed. 123.
