This study aimed at validating Iowa Oral Performance Instrument (IOPI), a tongue pressure measurement tool, as a screening tool of oropharyngeal dysphagia in Hong Kong geriatric population. 8 dysphagic and 26 non-dysphaic elderly who aged 60 or above were recruited for oral motor examinations, trial swallow tests and the measurements of tongue peak pressure with IOPI. The results showed a significant difference in the tongue peak pressure between dysphagic and non-dysphagic group, a high inter- and intra-rater reliability of the measurement and a strong correlation between tongue peak pressure and the rating of oral motor examination. The result supported that the measurement of tongue peak pressure is a valid and reliable screening method of oropharyngeal dysphagia.published_or_final_versionSpeech and Hearing SciencesBachelorBachelor of Science in Speech and Hearing Science
