Abstract: Cerebral palsy is a neuromuscular disease that is often complicated by nutritional problems in children and adolescents. At the same time, violations of the nutritional status are a frequent manifestation of the underlying disease, worsen its course and reduce the effectiveness of rehabilitation. The currently used classification of forms of cerebral palsy does not reflect the overall severity of the disease, expressed in the degree of impairment of motor functions, which is important in clinical practice. The article discusses the possibility of using the GMFCS classification to assess the severity of movement disorders in children with cerebral palsy.
