What is the most common voice quality associated with dysarthria in clients with amyotrophic lateral sclerosis?

• A. Harsh, strained voice quality
• B. Breathy voice quality
• C. Clear voice quality
• D. Raspy voice quality

Answer: (A)

The most common voice quality associated with dysarthria in clients with amyotrophic lateral sclerosis (ALS) is characterized as having a harsh, strained quality. This is primarily due to the progressive neurological degeneration that impacts the muscles involved in speaking. In ALS, the motor neurons that control voluntary muscle movements, including those necessary for phonation, become damaged. This leads to a breakdown in the coordination and strength of the vocal cords, often resulting in a strain or tension in the voice. Individuals with this type of dysarthria may struggle to maintain a steady airflow, leading to a voice that sounds tight and strained. The harshness of the voice is notable as it contrasts with other types of voice qualities that may be present in different speech disorders. Understanding this specific voice quality is crucial for speech-language pathologists when assessing and developing therapeutic strategies for clients with ALS.
