The purpose of this study was twofold: first, to compare normal adults and adults demonstrating dysarthria on three measures of oral sensation and perception; and second, to determine whether sensory deficit in the dysarthric Ss, if present, was significantly related to severity of dysarthria and speech intelligibility. Results indicate the dysarthric Ss displayed significant oral sensory and perceptual deficit on all three measures; however, correlations among oral sensory and perceptual deficit, severity of dysarthria, and speech intelligibility were not significant.
