Abstract: Objective：To analyze the motor function and prognosis of different subtypes of dyskinetic cerebral palsy.Methods：A retrospective survey of 46 cases of dyskinetic cerebral palsy who were treated in Nanhai Affiliated Maternity and Children Hospital of Guangzhou TCM University from January 2005 to October 2009 was carried out.Based on the clinical characteristics,all the patients were divided into 3 types:dystonic type,chorea-athetoid type and athetoid-spastic type.Files of GMFCS classification and GMFM-88 assessment were collected and analyzed.Results：There was significant difference of GMFCS levels among the 3 types.Chorathetoid type had the highest level and the athetoid-spastic type had the lowestF=71.596,P<0.001).Each functional area of GMFM-88 scale in athetoid-spastic type was significantly lower than that of the Chorea-athetoid type(P<0.001).The scale of standing position,walking,running and jumping area of dystonic type was significantly lower than that of Chorea-athetoid type(P<0.001).Conclusions：Most children of Chorea-athetoid type can obtain their own walking ability before 4 years old.Some children of dystonic type can obtain their own walking ability.Children of athetoid-spastic type have significant motor delay compared with other types and have difficulty in obtaining their own walking ability
