The relationship between age of walking and two factors of severity of intellectual disability and clinical types (autism, Down syndrome, epilepsy, and "residual") in children with mental retardation was investigated. Subjects were 118 children whose disabilities ranged from severe to mild. Measures by clinical type were significant, and the differences of any two clinical types except between children with epilepsy and the "residual" group were significant, but severity of intellectual disability was not significant. Most children with autism (27 subjects, 93%) walked by the normal time limit of 18 months. Only 3 children (11%) with Down syndrome began to walk within that limit, and 9 of them (33%) walked after 2 years of age. In the "residual" group (including children with epilepsy), 37 children (60%) walked within the normal limit but 15 (25%) only after 2 years of age.
研究了智力发育迟缓儿童开始走路的年龄与智力残疾严重程度及临床类型（自闭症、唐氏综合征、癫痫和“其他”）这两个因素之间的关系。研究对象为118名残疾程度从重度到轻度的儿童。按临床类型分类的测量结果具有显著差异，除癫痫患儿与“其他”组之间外，任何两种临床类型之间的差异均具有显著性，但智力残疾严重程度差异不显著。大多数自闭症儿童（27名受试者，93%）在18个月的正常时限内开始走路。唐氏综合征儿童中只有3名（11%）在该时限内开始走路，其中9名（33%）在2岁以后开始走路。在“其他”组（包括癫痫患儿）中，37名儿童（60%）在正常时限内开始走路，但15名（25%）在2岁以后才开始走路。
