The use of selected clinical observation to predict postrotary nystagmus change in learning disabled children

Twenty-six children diagnosed as learning disabled and displaying hypo responsive postrotary nystagmus were divided on the basis of four measures of vestibular-proprioceptive function commonly employed by therapists to evaluate reflex integration and postural mechanism. Data analysis revealed that learning disabled children combined hypo responsive postrotary nystagmus and associated vestibular-proprioceptive deficits were more likely to eveidence increases in postrotary nystagmuch durations following sensory integrative therapy. Results are discussed in terms of the relationship between hyporesponsice postrotary nystagmus and clinical measures to vestibular-proprioceptive functions. The possible existence of separate identifiable syndromes of vestibular processing dysfunction and their respective reponsiveness to sensory integrative therapy are examined.
