Short phrases may be observed in which type of dysarthria?

Short phrases are commonly observed in spastic dysarthria, which is characterized by increased muscle tone and spasticity affecting the speaking mechanisms. The nature of spastic dysarthria leads to difficulties with the coordination and execution of speech, contributing to a disrupted flow. Individuals with this type of dysarthria may exhibit strained or effortful speech, and their speech may become more choppy, leading to the use of shorter phrases. This is due to the overactivity of muscles, which can affect respiratory control and the timing of speech production, causing individuals to produce less fluid, shorter utterances.

In contrast, other types of dysarthria present with different characteristics. For example, ataxic dysarthria involves coordination problems that can lead to a more irregular speech pattern, flaccid dysarthria is characterized by weak muscle tone that may result in a softer voice and reduced speech clarity, while hyperkinetic dysarthria often features involuntary movements that can disrupt normal speech rhythm and may lead to longer pauses or uneven speech without the same pattern of brevity as seen in spastic dysarthria. Thus, the unique attributes of spastic dysarthria make it the most appropriate choice regarding the use of short phrases in speech.
