Types of Dysarthria

Question 1

What are some deviant speech characteristics of Hypokinetic Dysarthria?

Answer 1

Rigidity, Reduced ROM, & fast/repetitive speech movements

Question 2

What causes deviant speech characteristics in Hypokinetic dysarthria?

Answer 2

Comprised function of the basal ganglia

Question 3

What are some speech characteristics of Hypokinetic Dysarthria

Answer 3

Monopitch, reduced stress, monoloudness, imprecise consonants, inappropriate silences, short rushes - unique for this types of dysarthria, harsh vocal quality, breathy voice (continuous), pitch level, variable rate.

Question 4

What are some respiration characteristics of Hypokinetic Dysarthria?

Answer 4

faster than normal breathing, reduced ROM of the respiratory muscles and shallow breath support, reduced VC
(all of these may lead to short rushes of speech and partly account for the soft voice)

Question 5

What are some phonation characteristics of Hypokinetic Dysarthria?

Answer 5

Harsh or breathy voice quality

Question 6

What are some articulation characteristics of Hypokinetic Dysarthria?

Answer 6

Imprecise consonants due to reduced ROM, stop consonants don’t receive full closure, fricatives may have a larger area of constriction, affricates have a combination of these two factors. Repeated phonemes or ‘palilalia’ – a compulsive, increasingly rapid repetition of a word or phrase. Similar to a festinating gait, where the person cannot stop themselves from walking past their destination

Question 7
