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 |
