{"doi":"10.1002/lary.30782","title":"Concurrent Validity of the <scp>IOPI</scp> and Tongueometer Orofacial Strength Measurement Devices","abstract":"Objective(s) This study examined the concurrent validity of two orofacial strength manometers: (1) the Iowa Oral Performance Instrument (IOPI) – the current, gold standard orofacial manometer; and (2) the Tongueometer – a newly‐available, lower cost, orofacial manometer. Methods This study compared IOPI and Tongueometer pressure readings across three experimental conditions. Experiment 1 compared full setup (manometer + tongue bulb) pressure readings between the IOPI and Tongueometer. Experiment 2 compared IOPI tongue bulb and Tongueometer tongue bulb pressure readings, while controlling for manometer. Experiment 3 compared IOPI manometer and Tongueometer manometer pressure readings, while controlling for tongue bulb. Pressures were applied manually within a laboratory setting. Lin's concordance correlation ( ρ c ) was used to calculate level of agreement, with ρ c interpreted as ‘poor’ if &lt;0.90, ‘moderate’ if 0.90 to &lt;0.95, ‘substantial’ if 0.95 to &lt;0.99, and ‘excellent’ if ≥0.99. Results 539 trials were analyzed. There was a median absolute difference of 2.4 kPa in pressure readings between the IOPI and Tongueometer full setups (manometer + tongue bulb). Correlations revealed substantial agreement between IOPI and Tongueometer full setups (experiment 1: n = 292; ρ c = 0.986), tongue bulbs (experiment 2: n = 146; ρ c = 0.987–0.992), and manometers (experiment 3: n = 101; ρ c = 0.970). Conclusions Differences in pressures were consistently observed between the Tongueometer and IOPI. Despite these differences, substantial agreement was present. These data suggest the Tongueometer may be a valid, lower cost alternative to the IOPI for objectively assessing orofacial strength in clinical practice.
