Shear wave elastography is a quantitative method for assessing tongue dysfunction in bulbar-onset amyotrophic lateral sclerosis

Key Points

• Tongue dysfunction is assessed quantitatively using shear wave elastography, providing important insights on bulbar-onset ALS.
• A significant finding is the link between the degree of tongue dysfunction and the progression of bulbar-onset amyotrophic lateral sclerosis.
• This observational analysis method employs elastography to measure tissue stiffness, focusing on tongue muscle assessment.
• These findings highlight the potential of shear wave elastography as a critical tool for diagnosing and monitoring tongue-related issues in ALS.
