ABSTRACT

The involvement of neurological deficits in the vestibular-postural and oculomotor systems of learning disabled children is controversial at two levels. Firstly the theoretical accounts put forward by such writers as A. J. Ayres, C. H. Delacato and H. J. Levinson are either inconsistent with current neurological and neuropsychological theory or too speculative to be acceptable. Secondly there is some debate as to the incidence of such disorders if they are to play any causative role. Neuroanatomical and neurophysiological reviews emphasise the close association of vestibular, proprioceptive oculomotor and cerebellar mechanisms. Vestibular-postural dysfunction was noted in our study across a range of measures. Signs of vestibular-postural dysfunction, reported in younger age groups were apparent in this study's older age group. Poor motor performance, as determined by psychometric assessment or clinically determined as neurological soft signs has been regarded as a predominant feature of minimal brain dysfunction.
