What is a defining feature of prosodic excess in spastic dysarthria?

• A. Reduced speech rate and increased pitch variability
• B. Equal stress and slow rate of speech
• C. Short phrases with high volume
• D. Monopitch with rapid speech

Answer: (B)

A defining feature of prosodic excess in spastic dysarthria is characterized by equal stress and a slow rate of speech. Prosodic excess refers to the unnatural rhythm and intonation patterns that can occur in this type of dysarthria, where speech sounds monotonous and effortful. In spastic dysarthria, the speech mechanism is often impaired due to the inability to properly control the muscles involved in speech production, leading to the characteristic equal stress across syllables and a slower delivery of speech.

This is important to identify because it contrasts with other speech characteristics that may be present in different types of dysarthria, where speech might be more rapid or vary in pitch and stress. By understanding these patterns, clinicians can better diagnose and treat individuals with spastic dysarthria, focusing on strategies that address the prosodic features of their speech.
