Which of the following is a common characteristic of both Hypokinetic and Hyperkinetic Dysarthria?

Imprecise consonants is a common characteristic of both Hypokinetic and Hyperkinetic Dysarthria because these types of dysarthria both contribute to difficulties in articulation, leading to a lack of clarity in speech sounds. In Hypokinetic Dysarthria, which is often associated with conditions like Parkinson's disease, muscle rigidity and reduced movement can hinder precise articulation. Similarly, Hyperkinetic Dysarthria, associated with conditions such as chorea or dystonia, can lead to overly variable speech production and errors in articulation due to involuntary movements. This results in both types presenting with imprecise consonants as a significant speech characteristic.

Other characteristics listed are more distinctly associated with specific types of dysarthria. Prolonged speech pauses may be observed in hypokinetic dysarthria, due to hesitation in speech secondary to the reduction in movement. Harsh vocal quality is more typical of spastic dysarthria or can be present in hyperkinetic types but is not a key feature of hypokinetic dysarthria. Increased speech rate is often seen in hyperkinetic dysarthria, particularly with certain movement disorders, but it is not characteristic of hypokinetic dysarthria, where a slower rate is often noted.
