Then, the aim of the study is to evaluate the efficacy of robotic-assisted therapy in children with cerebral palsy by evaluating the 3 fields of the ICF (International Classification of Functioning, Disability and Health) and performing a prospective randomized controlled single blind trial. Therefore, all patients will benefit from a classical rehabilitation as a basis. Furthermore, patients of the control and experimental groups will receive a supplement of classical rehabilitation and robotic-assisted therapy, respectively.
