Brief Summary

A randomized, controlled, and evaluator-blinded trail will be carried out comparing CIMT with or without AOT on sensorimotor outcome in children with unilateral CP aged 5 to 12 years. Additionally the potential role of neurological factors, including the anatomical characterization of the brain lesion, structural/functional connectivity and cortical reorganization, on treatment response will be investigated.

Detailed Description

Background: Problems in upper limb (UL) function in children with unilateral cerebral palsy (UCP) are traditionally trained with motor execution treatment models, such as Constraint Induced Movement Therapy (CIMT). However new approaches based on a neurophysiological model such as action observation training (AOT) may provide new opportunities for enhanced motor learning.

Aim: The aim of study is to investigate the effects of an intensive treatment model consisting of CIMT and AOT compared to CIMT alone on UL function in children with UCP. Additionally the potential role of neurological factors (including the anatomical characterization of the brain lesion, structural/functional connectivity and cortical reorganization) on treatment response will be analysed.

Methods/Design: A randomized, controlled, evaluator-blinded trial (RCT) will be conducted in 40 children between 5 and 12 years of age. Before randomization, children are stratified according to their House Functional Classification Scale, age and type of cortical reorganization. The Intervention is accomplished during a 2-week day camp in which the children receive intensive therapy for six hours a day on 9 out of 11 consecutive days (54 h) including AOT or placebo observation training (POT) (15h). During the AOT the children in the experimental group watch video sequences showing goal-directed actions and subsequently execute the observed actions with the affected UL. Children in the POT group perform the same actions after watching computer games without biological movements.

Outcome assessments include qualitative and quantitative measures of UL sensorimotor function across the International Classification of Functioning, Disability and Health (ICF). The primary outcome measure is the Assisting Hand Assessment (AHA). The medical imaging protocol includes structural Magnetic Resonance Imaging (MRI), Diffusion Kurtosis Imaging (DKI), resting state functional MRI (rs-fMRI) and Transcranial magnetic stimulation (TMS). The timeline for the assessment is T0 (1-1.5 month before the camp onset), T1 (before the intervention), T2 (after the intervention) and T3 (6 months after the intervention). Linear mixed models will be used to study time effects of the interventions and the interaction with neurological variables as covariates.

GroupInterventionDescription
CIMT + AOTAction observation trainingIn a 2-week day camp model children receive constraint-induced movement therapy for six hours a day, for 9 out of 11 consecutive days. All children wear a tailor made hand splint on the unaffected upper limb for 6 hours per day while performing unimanual exercises individually or in a group based on shaping and repetitive practice. Action observation training consists of 15 sessions of 1 hour. Children watch video sequences showing goal-directed actions and subsequently execute the observed actions with the affected upper limb.
