Research output: Contribution to journalArticlepeer-review


With the exception of lthe pioneering work by Damste in the mid 1960's and early 70's, no long term quantitative research on voice changes subsequent to drug therapy has been reported. This study reports the effects of a specific cortico-steroid, triamcinolone acetonide, on selected aerodynamic and acoustic parameters reflecting the vocal performance of twenty-one chronic asthmatic steroid dependent individuals. Measurements of the subjects' vocal fundamental frequency, maximum phonation time, oral air volume velocity, and peak intra-oral air pressure during production of selected speech stimuli were made before the introduction of triamcinolone and following the first and second years of drug use. After two years of triamcinolone therapy, significant changes were noted in parameters reflecting laryngeal functioning. Respiratory performance remained unchanged for most subjects. The results are discussed in terms of the possible physiological changes that might have occurred and their implications for the speech-language pathologist and speech scientist in medical management.
