Characterizing motor speech disorders

Question 1

What are the variables of interest in an oral mech?

Answer 1

size, position, strength, speed, ROM, steadiness, tone, accuracy

Question 2

What is the modified feeding approach for an oral mech?

Answer 2

strategic placement of food designed to elicit movements of targeted structures

Question 3

How do you test for nonverbal oral apraxia?

Answer 3

look for palatal elevation during crying, laughing;
ROM of structures during yawning, vocal play
volume/loudness during vocal play, crying to infer respiratory support

Question 4

What are the different types of DDK?

Answer 4

AMR: repetition of a single syllable
SMR: repetition of a syllable sequence

Question 5

People with AOS are better at which type of DDK?

Answer 5

AMR

Question 6

Can we use DDK to make inferences about speed or regularity of tongue movement for connected speech?

Answer 6

no. ROM unrelated to DDK rate or regularity.

Question 7

What are some ways to evaluate respiratory-laryngeal functions?

Answer 7

low tech manometer
cough (weakness could be bad adductor and/or poor respiratory support)
grunt/glottal coup

Question 8

What are some measures used to characterize motor speech disorders?

Answer 8

vowel prolongation, auditory perceptual evaluation of speech breathing, auditory perceptual evaluation of voice, articulation (perceptual and instrumental measures), contextual speech , intelligibility, functional communication

Question 9

What are some measures of intelligibility?

Answer 9

interval scaling/percent estimates
PCC (children)
orthographic transcription from spontaneous speech
Direct Magnitude Estimation (DME)
Visual analog scale
Published tests

Question 10

What is the difference between intelligibility and comprehensibility?

Answer 10

intelligibility: how well can a listener understand the ACOUSTIC SIGNAL? (indexing functional impairment (of speech system??))
comprehensibility: how well can a listener understand? (includes content I guess?) (indexing disability)

Question 11

What are some issues with the DAB method of classification?

Answer 11

many symptoms and clusters of characteristics to master
clinician listening experience required
symptoms may be variable
similar symptoms may result from different disease processes
measurement reliability
