Abstract
DESIGN
A multisite, prospective, and randomized within-subject design study.
SETTING
Five university settings in varied geographical areas in the United States.
PURPOSE
The purpose of this study was to compare lingual pressure generation using the Tongueometer (TO) and the Iowa Oral Performance Instrument (IOPI) in typically aging, community-dwelling adults during three measurement tasks: maximum isometric pressure (MIP), regular effort saliva swallow (RESS) pressure, and effortful saliva swallow pressure (ESP).
PARTICIPANTS
Eighty-seven typically aging, community-dwelling adults (aged 55 years and over) with no self-reported history of swallowing or neurological disorders were recruited to complete this study.
RESULTS
Strong positive associations were found between the lingual pressure generation measures from the TO and IOPI in all tasks in typically aging adults, with Pearson correlations ranging from r = .780 to .874, p < .001. Agreement between the devices (Lin's concordance correlation coefficient) ranged from moderate for the MIP (ρc = .78) and ESP (ρc = .61) tasks to weak agreement for the RESS task (ρc = .47). MIP, RESS pressure, and ESP were lower when measured by the TO compared with the IOPI, p < .001.
CONCLUSIONS
The TO measures lingual pressure generation similarly to the IOPI but pressures register lower when using the TO than the IOPI in typically aging persons. This supports the need for developing normative values specific to the TO device or development of a valid and reliable conversion formula from TO to IOPI normative values. At this time, the clinical use of reference values from the TO should not be generalized to IOPI normative values.
