Cerebral Palsy (CP) is one of the most common reasons for physical disability in children. There are numerous factors that affect the development of this disease which occur predominantly in the perinatal period. The aim of this report is to highlight new possibilities for treating cerebral palsy with stem cells, based on a literature review with the focus on a clinical case from a Child Neurology Department in Lublin, eastern Poland. To date, treatment methods have not had good results. A future alternative is the administration of stem cells. The clinical case presented is evidence that further research is needed to improve this new treatment method. Among all the symptoms of CP, the most important is reduction in muscle tone in the children, and stem cell administration reduces the spasticity. Intensive rehabilitation and support from psychologists and neurologists are still the primary means of improving the performance of patients with CP.
