Cerebral Palsy Hypoxic-Ischemic Encephalopathy Intracranial Hemorrhage

This study evaluates the safety and preliminary efficacy of autologous bone marrow mononuclear cell transplantation combined with rehabilitation in children with neurological sequelae caused by hypoxic-ischemic brain injury or intracranial hemorrhage. Participants in the intervention group will receive autologous bone marrow aspiration, mononuclear cell transplantation via intrathecal route, and rehabilitation, while the control group will receive rehabilitation alone. Outcomes will be compared between groups over follow-up time points.
