Official Title: Quantified Analysis of the Movements of the Upper Limb of Children With Hemiparesis Participating in the Stress Induced Therapy Program
Brief Summary: In France, Cerebral Palsy (CP) affects 1 in 450 births. It results from lesions of the brain, before, during, or shortly after birth. These non-progressive lesions cause muscle impairments, responsible for activity limitations. These muscle impairments include muscle stiffness, and muscle weakness. Children with Unilateral CP (UCP) have these impairments on only one side of the body. To compensate for activity limitations with their impaired arm, these children over-use their non-impaired arm. The objective of constraint-induced therapy (CIT) is to minimize this asymmetry which deteriorates mobility on the impaired side, by forcing the child to only use its impaired arm several hours a day during several weeks of therapy. It is known using clinical tests that this therapy improves the overall motor function of the impaired arm. However, the underlying mechanisms are yet unknown. An understanding of these mechanisms would suggest ways to maximize the effectiveness of this therapy, which requires a significant commitment from the child and its family. The investigaors propose in this project a quantitative and objective evaluation of the effect of CIT on the movements of the impaired arm of children with UCP. The investogators focus their analysis on muscle activation, to assess which aspect of muscle impairments is modified by CIT. To this end, the investigators will use sensors identical to those already used in clinics for the Quantified Gait Analysis of children with CP, recognized since 2006 by the Haute Autorité de Santé as providing key supplementary data in the evaluation of complex gait disorders. Results from this study will provide leads to optimize CIT. Some children could for example benefit from CIT paired with treatments to reduce muscle stiffness or to strengthen muscles
