 This study found that the prototype device used to measure tongue force had a strong correlation, are greater than 0.97, and an excellent reliability, ICC 0.90, when compared to the algometer. Additionally, the inter-rater reliability analysis showed an excellent ICC, 0.93, with a 95% CI of 0.86 to 0.97 and a MDC 90 of 6.26n. Therefore, the results suggest that the prototype device can be used as a reliable tool for measuring tongue force in clinical settings.
