[Neurodevelopmental outcome of children with idiopathic toe-walking].

Twenty-six children with idiopathic toe-walking (ITW) were evaluated as to their neurodevelopmental outcome by means of a follow-up study. The ages of the subjects at the last follow-up ranged from 3 years and 4 months to 14 years and 10 months (mean: 7 years and 4 months). The neurodevelopmental outcome in the subjects was normal intelligence in 22 (of which 5 were clumsy and 4 were hyperkinetic), and borderline intelligence in 4 (of which 2 were clumsy). Thus, 13 of the 26 cases (50%) had neurodevelopmental problems including clumsiness and hyperkinesia. It is noteworthy that there was a high rate of the neurodevelopmental problems among the children with ITW. The clinical course of children with ITW should be carefully followed-up, and the appropriate care and intervention should be given to them, when the children are found to have these problems.
