A preliminary investigation was conducted into the relationship of the Southern California Sensory Integration Tests (SCSIT), the Southern California Postrotary Nystagmus Test (SCPNT), and clinical observations accompanying these tests to evaluations in otolaryngology, ophthalmology, and audiology. The subjects were two children with vestibularly based sensory integrative dysfunction. The results revealed that there was no agreement between the results of the SCPNT and the otolaryngological evaluation. There was some agreement between the ophthalmology evaluation and the clinical observations accompanying the SCSIT. Both subjects scored poorly in two areas of auditory processing. Possible reasons for these results are discussed as well as implications for occupational therapy research and practice.
