Intramuscular condition of swallowing‐related muscles using shear‐wave elastography: A preliminary study in healthy adults

Stiffness of the posterior GGM was positively correlated with BMI and that of the GHM was negatively correlated with BMI. Stiffness, as measured using SWE, has the potential to capture the intramuscular characteristics of swallowing-related muscles, particularly the posterior GGM.
