Postrotatory nystagmus duration as a function of communication disorders.
The purpose of this study was to explore the relationship between functioning of the vestibular system, measured by duration of postrotatory mystagmus, and specific communiccation disorders (articulation, speech and language, and language). A total of 190 children participated in the study, 173 of which were included in the final data analysis. The findings revealed a depressed mean duration of postrotatory nystagmus in all categories of communication disorders when compared to the control group. In addition, the language group had a sig;ificantly lower mean duration of postrotatory nystagmus when compared to the articulation and speech and language groups. Although the test measure did discriminate between groups, it did not discriminate well between children within groups.
