Abstract

This study explores the effect of a program of sensory integration therapy, with emphasis on vestibular stimulation activities, on the duration of postrotary nystagmus in three learning-disabled children. The single-subject methodology employed allowed a more individualistic and longitudinal investigation of nystagmus patterns in the three subjects. The graphic and statistical analysis of the data revealed that two of the three subjects evidenced significant changes in postrotary nystagmus durations over the 25-week period of the study. Subject 1, with initially low nystagmus durations, displayed an increase in duration, whereas subject 2, with initially normal postrotary nystagmus durations, exhibited a response decline in nystagmus durations. The postrotary nystagmus durations of subject 2 remained relatively stable across both the baseline and intervention periods. The therapeutic implications of the findings are discussed, and areas in need of additional investigation are highlighted.
