Randomized controlled trials

Five of the 12 studies investigated the effect of tongue strength exercise training in individuals with stroke or cancer diagnoses. Findings demonstrated nonsignificant effects of tongue strength exercise training on increased anterior and posterior tongue strength compared to control groups receiving traditional swallowing treatment. Given the small number of studies, varying comparisons and mixed etiologies, further research is warranted.
