The aim of this study is to test the hypothesis, that improvements in gait pattern following individually tailored interventions guided by instrumented 3-dimensional gait analysis are superior to those used in 'care as usual'.
Children with cerebral palsy (CP) who walk independently often have an altered gait pattern. Interdisciplinary interventions in terms of orthopaedic surgery, spasticity management, physical therapy and orthotics aim to improve the gait pattern. Standardised measurements are used in the Cerebral Palsy follow-Up Program to assess walking. However, these measurements do not describe features in the gait pattern reflecting underlying neuro-musculoskeletal impairments. This can be done with instrumented 3-dimensional gait analysis (IGA). It has never been investigated whether interdisciplinary interventions designed to address impairments identified by IGA result in improved gait pattern compared with 'care as usual' without IGA in children with CP. The aim of this study is to test the hypothesis, that improvements in gait pattern following individually tailored interventions guided by IGA are superior to those used in 'care as usual'. A prospective, single blind, randomised, parallel group study will be conducted. Participants will be recruited from the Cerebral Palsy follow-Up Program. Children aged 5 to 9 years with spastic CP, classified at Gross Motor Function Classification System levels I or II will be included. The interventions under investigation are 1) Individually tailored interdisciplinary intervention addressing impairments identified by IGA and 2) 'care as usual' (interdisciplinary interventions without IGA). The primary outcome is gait pattern measured by the Gait Deviation Index. Secondary outcome measures are, walking performance and patient-reported outcomes of functional mobility, health-related quality of life and overall health, pain and participation. Explorative outcome measures include walking performance, gait pattern, behavior of health care providers and the applied interventions. The primary endpoint for assessing the outcome of the two interventions will be 52 weeks after start of intervention. A follow up will also be performed at 26 weeks after start of intervention; however, exclusively for the patient-reported outcomes. To our knowledge, this is the first randomised controlled trial comparing the effects of an individually tailored interdisciplinary intervention designed to address impairments identified by IGA versus 'care as usual' in children with CP. Consequently, the study will provide novel evidence for the use of IGA in interdisciplinary interventions.

Individually tailored interdisciplinary intervention based on measures performed as part of the Cerebral Palsy follow-Up Program and other clinical examinations AND instrumented gait analysis The instrumented gait analysis consists of four steps: 1. Instrumented gait analysis (data collection with a 8-camera Vicon T40 system (Vicon, Oxford, UK) and 2 force plates (AMTI, OR6-7-1000) 2. Impairment-Focused Interpretation 3. Recommendation for interdisciplinary interventions 4. Dissemination of recommendations The two modalities differs in the use of IGA, but the study is not indented to document the effect of IGA alone, but to document the difference in the effects of the interdisciplinary interventions, when IGA is implemented to the experimental group.

Change from baseline in Gait Deviation Index
Gait Deviation Index (GDI) is based upon kinematic data from the Instrumented Gait Analysis, and is an quantitative index that summarises the overall gait pattern into a single score for each patient by comparison with non-pathological gait. A GDI value of 100 represents the absence of gait pathology, and each 10-point decrement below 100 indicates one standard deviation from normal gait kinematics. For the primary outcome measure, the median of five trials for each leg will be used to calculate the average of both legs to provide a single index for each child.
Time frame: Baseline, 52 weeks
Change from baseline in 1-minute walk test
Walking performance is assessed with the 1-minute walk test. The test measure the distance in meters, when the child walks as fast as possible.
Time frame: Baseline, 52 weeks
Change from baseline in Mobility Scale of the Pediatric Evaluation of Disability Inventory
The Mobility Scale of the Pediatric Evaluation of Disability Inventory evaluates the child's functional mobility in everyday activities with regard to functional skills and caregiver assistance. The Paediatric Evaluation of Disability Inventory will be applied as a parental questionnaire, allowing comparison of the child's functional skills over time for each of the two dimensions.
Time frame: Baseline, 52 weeks
Change from baseline in Pediatric Quality of Life Inventory Cerebral Palsy Module
The Pediatric Quality of Life Inventory Cerebral Palsy Module is a measure of health-related quality of life, specifically designed for children with CP. The Pediatric Quality of Life Inventory Cerebral Palsy Module is based upon the parents' report and measures physical, emotional, social and school functioning.
Time frame: Baseline, 52 weeks
