How is articulation affected in spastic dysarthria?

• A. Clear consonants and vowels
• B. Imprecise consonants and vowel distortion
• C. Consistent speech sounds
• D. Perfectly articulated words

Answer: (B)

In spastic dysarthria, articulation is characterized by imprecise consonants and vowel distortion due to the hypertonicity and spasticity of the muscles involved in speech production. The neurological underpinnings of this type of dysarthria lead to increased muscle tone and reduced range of motion, which can result in difficulty with movements necessary for speech articulation. This affects the clarity and precision of both consonants and vowels, leading to the distortion of speech sounds.

The other options do not accurately reflect the characteristics of spastic dysarthria. Clear consonants and vowels would suggest a high level of precision and control that is not typically present in this condition. Similarly, the notion of consistent speech sounds or perfectly articulated words contradicts the hallmark imprecision associated with spastic dysarthria. Therefore, the answer highlighting imprecise consonants and vowel distortion accurately captures the articulation challenges faced by individuals with spastic dysarthria.
