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.MethodsThis 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 (ρc) was used to calculate level of agreement, with ρc interpreted as ‘poor’ if <0.90, ‘moderate’ if 0.90 to <0.95, ‘substantial’ if 0.95 to <0.99, and ‘excellent’ if ≥0.99.Results539 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; ρc = 0.986), tongue bulbs (experiment 2: n = 146; ρc = 0.987–0.992), and manometers (experiment 3: n = 101; ρc = 0.970).ConclusionsDifferences 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.Level of EvidenceLevel 2 Laryngoscope, 133:3123–3131, 2023
