GM1 Acupoint Injection Improves Mental Retardation in Children with Cerebral Palsy.

To study the clinical effectiveness and mechanism of GM1 acupoint injection therapy on mental retardation for children with cerebral palsy (CP). A total of 90 children with CP were divided into acupoint injection group (group A), subcutaneous injection group (group B), and control group (group C). Another 30 healthy children were set as a healthy control group (group D). The Mental Developmental Index (MDI), Psychomotor Developmental Index (PDI), and hemodynamic parameters in the cerebral arteries were measured before and after treatment. After three treatment courses, the MDI and PDI in groups A, B, and C were increased, and the increase in group A was most obvious (P < 0.05). Peak systolic velocity, mean velocity, and end-diastolic velocity were also elevated in group A, and after three treatment courses, resistance index decreased with a statistical significance (P < 0.05). However, there were no significant changes in groups B and C (P > 0.05). For all groups, neuron-specific enolase levels decreased and total superoxide dismutase increased after treatment. Acupoint injection therapy combined with conventional rehabilitation therapy demonstrated significant effects on cerebral hemodynamic conditions for children with CP.
