Age of walking in the cognitively impaired

Age levels for independent walking were compared for groups of children with varying degrees of intellectual impairment, but without other neurologic handicaps. All walked independently, save for 13.5 per cent of the profoundly retarded. Although mental retardation was associated with a delay in walking, subgroups existed at all levels that walked at a normal age. This suggests that the cognitive level is not the sole determinant for the achievement of this milestone.
