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 (<jats:italic>\u03c1<\/jats:italic><jats:sub>c<\/jats:sub>) was used to calculate level of agreement, with <jats:italic>\u03c1<\/jats:italic><jats:sub>c<\/jats:sub> interpreted as \u2018poor\u2019 if &lt;0.90, \u2018moderate\u2019 if 0.90 to &lt;0.95, \u2018substantial\u2019 if 0.95 to &lt;0.99, and \u2018excellent\u2019 if \u22650.99.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>539 trials were analyzed.
