Ataxic Dysarthria

Question 4

Name the dysarthria:

Characterized by rigidity, tremor at rest, paucity of movement, slowness, limited range of movement, and limited force of muscle contraction. Neurological damage of portions of basal ganglia (substantia nigra)

Answer 4

Question 5

Name the dysarthria:

Referred to as the slow type. Picture is one of muscle contraction that build up slow producing a distorted posture. Muscles of head, neck, trunk, and proximal limbs typically involved. May be focal or generalized. Basal ganglia damage

Answer 5

Hyperkinetic Dysarthria (Dystonia)

Question 6

Name the dysarthria:

Referred to as quick hyperkinesia. Picture is one of random, unrestrained, rapid, irregular movements. Hypotonia and incoordination. Pattern of clusters is complex.

Answer 6

Hyperkinetic Dysarthria (Chorea)

Question 7
