Pressure profile similarities between tongue resistance training tasks and liquid swallows

Catriona M. Steele, PhD, et al.


Figure 3. Forest plot showing the overlap in mean and 95% confidence interval for tongue-pressure release slope, measured at posterior palate, during eight different tasks: discrete water swallow (DSW), discrete nectar-thick apple juice swallow (DSANEC), noneffortful saliva swallow (NESS), effortful saliva swallow (ESS), posterior emphasis half-maximumtongue-palate press (PHMAX), PHMAX performed at slow rate (PHMAXSLOW); PHMAX performed at fast rate (PHMAXFAST), and posterior-emphasis maximum isometric tongue-palate press (PMAXTP). Dashed lines outline interval capturing release-slope values for DSW and DSANEC. Tasks with mean and confidence interval boundaries falling outside these lines differ from these bolus swallowing tasks in release slope.

Swallowing problems are a serious concern for many veterans, elderly people, and individuals with strokes or brain injuries. Tongue function is critical for swallowing. Research suggests that tongue resistance exercises can improve strength but not whether they improve swallowing. This study explored how nondisabled people apply tongue pressure to liquids during swallowing and compared these pressure patterns with those seen during different tongue resistance exercises. We identified tongue resistance exercise tasks with similar pressure profiles to nondisabled swallowing. We suggest that treatment should focus on these tasks to have the best chance of improving swallowing.
