Cerebral palsy prevalence and risk factors clinical manifestation when the children were young, especially spastic hemiplegia, which means that the prevalence of CP may be under-represented. This work was supported by grants from the Health Industry Special Scientific Research Project (grant number 201002006) and the Henan provincial science and technology research project (grant number 201203053). We thank the paediatricians, rehabilitation physicians, and staffs in Zhengzhou, Xinxiang, Zhumadian, Kaifeng, Sanme- nxia, Shangqiu, Luohe, Puyang, Luoyang cities who helped in the epidemiological investigation.
