Apraxia PP Flashcards
What is ataxia?
Disordered movement characterized by over or under shooting of targets, discoordination, jerky slow and imprecise and poorly timed movements. 2/2 cerebllar damage
What is non verbal oral apraxia?
Unable to copy or follow commands to do volitional movements/functions of speech mechanism. This can’t be attributed to poor task comprehension, sensory or neuromuscular deficits (Ex. Sometimes a PT says cough instead of actually coughing)
What is limb apraxia?
Trouble organizing movements of right and left extremities. Sometimes only on demand, in formal testing.
What is apraxia of speech?
An acquired disorder. Hard to plan or program movements for sequential phoneme production for speech. Deficits in assembly, retrieval, and/or activation of motor programs for speech.
What does apraxia result from?
Pathology in left cerebral hemisphere
What other disorders may coexist with apraxia?
Aphasia and dysarthria.
What deficits do not account for apraxic errors?
Language deficits and deficits in muscle tone, strength endurance, coordination
What are signs and symptoms of apraxia of speech (AOS)?
Hard to sit up right, hard to move from one articulatory configuration to another, groping, trial and error behavior, increased errors when the words get longer and the phonemes get complex, their connected speech is poorer than isolated word production, altered suprasegmentals, try to correct themselves, inconsistent error patterns
What are phonemic paraphasias?
Involve the selection and production of the wrong phoneme or speech sound (ex. “T” in speat instead of speak
What do sound errors sound like in apraxia of speech?
Articulatory struggle, mistiming and distortion of sounds. For example, “speech “ being pronounced as stree skee skeech
What should you consider for intervention on someone with AOS?
That people change over time due to neuroplasticity, neural maturation and because of treatment
What are the principles of motor learning?
To maximize the # of response trials per session, to train correct movement patterns, don’t separate movement gestures, frequent short sessions, practice the movement in the context for which it is used, use severity of motor movement as your guide.
What are interfering factors for AOS?
Aphasia, non-verbal oral apraxia, depression, pride/acceptance, frustration, time, expectations
What is motor learning?
Process of getting the ability to produce skilled and refined action (playing an instrument, athletics)
