Motor Speech Midterm
Term | Definition |
---|---|
First step of Speech | Intent |
Second step of speech | Linguistic-symbolic planning |
Third step of speech | Motor Planning |
Fourth Step of speech | Motor Programming |
Fifth Step of Speech | Execution |
Intent | Desire to communicate |
Linguistic-Symbolic Planning | Finding the words to speak |
What results from damage at the level of linguistic/symbolic planning? | Aphasia type impairments |
Motor Planning | What articulators are moving |
What results from damage at the level of motor planning? | Apraxia |
Motor Programming | Programming/sequencing muscle movement for articulation, including rate, tone, tension, and amplitude |
What results from damage at the level of motor programming? | Dysarthria, except for Flaccid |
Execution | Innervation of muscles, the muscles themselves move using CN innervation |
What results from damage at the level of execution? | Flaccid dysarthria |
Dysarthria | Collective group reflecting abnormalities in speech strength, speed, range, steadiness, tone, or accuracy |
Dysarthria is not..... | Failure of linguistic competence |
3 things that are true of all dysarthria | Neurologic in origin, disorder of movement, categorized into different types |
2 ways to categorize dysarthria | Distinguishable perceptual features, underlying neuropathophysiology |
What is Apraxia? | Impaired capacity to plan or program |
Non-neurological disorders | Musculoskeletal deficits, developmental arctic issues, non-neuro voice disorders |
Dimensions of difference for dysarthria | Age of onset, cause, natural course, size of lesion, neuro disease, pathophysiology, speech subsystems involved |
Methods for dysarthria classification | Perceptual and instrumental |
Gold standard of dysarthria classification | Auditory-perceptual |
Supplementary or confirmatory support | Instrumental methods |
Major issue with auditory-perceptual | Subject to unreliability of judgement from clinicians |
Primary goal of speech treatment | Intelligibility |
