Ultrasonographic Measurements of Tongue Thickness and Swallowing Dysfunction in Amyotrophic Lateral Sclerosis: A Feasibility Study

Tongue ultrasonography may serve as a radiation-free method to preliminarily assess bulbar involvement in ALS. Tongue thickness was most specifically associated with dysphagia outcomes, particularly MBSImP. Given the feasibility design and small sample size, larger longitudinal studies are warranted to confirm its clinical utility in monitoring the progression of dysphagia in patients with ALS.
