ABSTRACT
Following an unfortunate iatrogenic incident, a 65 year old woman suffered hyponatremia and extrapontine myelinolysis which left her with severe disabilities, including quadriplegia and dysarthria. This case report describes acoustic analysis of her voice, speech, and language which was done using PRAAT software. She had severe dysphonia, and her speech involved slow and inaccurate articulator movements. Hypernasality was observed with an overall reduction in speech intelligibility. Hyperadduction of the true and false vocal cords during voice production was also observed. Speech therapists, as part of a multidisciplinary health team, are of great importance in the functional rehabilitation of such patients.
