Motor Disorders Flashcards
AOS 4 most salient characteristics:
1) effortful, trial and error, groping articulatory movements, and attempts at self- correction
2) dysprosody unrelieved by extended periods of normal rhythm, stress, and intonation
3) articulatory inconsistency on repeated productions of the same utterance
4) frequent articulatory errors (substitution, distortion, omission, additions, and repetitions)
T/F: Atrophy and fasciculations are not always seen in flaccid dysarthria but they are not seen in other MSDs
True
Characteristics of Hypokinetic Dysarthria
Facial masking, orofacial tremulousness and reduced ROM on nonspeech AMRs is most common in hypokinetic dysarthria
Monopitch, monoloudness, reduced loudness and stress, a tendency towards a rapid rate
Accelerated rate (only MSD that has this—but may not always be present)
Rapid and blurred AMRs
Most common strategies for achieving compensated intelligibility:
increasing loudness
overarticulation
modifying speech rate
Characteristics of Hyperkinetic Dysarthria
Quick or slow, patterned or unpatterned involuntary movements at rest, during sustained postures, or
AMRs are a strong confirmatory sign
Some hyperkinesias occur only during speech
The MSD where visual observation (of involuntary movements) is most useful/diagnostic
Helps to distinguish it from the irregularity seen in ataxic dysarthria
Unpredictable and variably involuntary movements affecting speech are key
Only MSD where abnormal noises can interfere with speech or be produced at rest
