OBJECTIVE: To study the therapeutic effects of neural stem cell transplantation on cerebral palsy rats. METHODS: Twenty-four rats were randomly divided into three groups: control group, model group and transplantation group. Animal models of cerebral palsy were made in the latter two groups. One week after modeling, rats in the transplantation group were injected 1 mL stem cell suspension (1×105) via the jugular vein, and rats in the control and model group were given the same volume of normal saline. Toe distance, step length and elevated body swing test in rats were detected, and histopathological changes in the rat brain were observed 3 weeks after transplantation. RESULTS AND CONCLUSION: In the model group, the toe distance and step length of the front left palm were significantly lower than those of the front right palm (P 0.05). Compared with the model group, the toe distance and step
