Decreased Maximal Tongue Protrusion Length May Predict the Presence of Dysphagia in Stroke Patients.

Objective: To investigate the relationship between maximal tongue protrusion length (MTPL) and dysphagia in post-stroke patients.

Methods: Free tongue length (FTL) was measured using the quick tongue-tie assessment tool and MTPL was measured using a transparent plastic ruler in 47 post-stroke patients. The MTPL-to-FTL (RMF) ratio was calculated.
