apraxia Flashcards
apraxia of speech
neurogenic speech disorder with deficits in motor planning and programming
features of apraxia
-slow overall speech rate
-increased sound distortions or distorted sound substituitons with increased utterance length or increased syllable/word articulatory complexity
-sound distortions
-groping
limb-kinetic apracia
-loss of kinetic functions for one limb
-usually their right hand, but can be other limbs
ideational apraxia
deficits in the execution of complex sequential movements. some consider it a severe form of ideomotor apraxia (pa ta ka)
ideomotor apraxia
deficits in execution of learned movements in spite of intact mobility, sensation, coordination, and comprehension (know how to cough, pucker, etc. but cant on command)
assessment of limb apraxia
-begin with least challenging tasks (pucker lips, smile)
-gestural tasks should include trails with imitation, trials on commands, and self generated trials
assessment of oral apraxia
-begin with least challenging gestures (nonrespiratory intransitive gestures) (close lips, stick out tongue)
-elicit responses under different conditions (with modeling, following commands, and self-generated trials)
primary diagnostic criteria
-slow rate of speech, including lengthened sound segments and intersegment durations
-sound distortions
-distorted, perceived sound substitutions
-inconsistent errors
-prosodic errors
nondiscriminative characteristics of AOS
-articulatory groping
-perseverative errors
-increasing errors with increasing word length
-deficits in speech initiation
-automatic speech better than propositional speech
treatment effects are examined based on 2 variables
-response generalization
-stimulus generalization
response generalization
-treatment effects are assessed based on performance of either untrained examples of trained behaviors
stimulus generalization
treatment effects are carried over outside of the therapy session (home, store, etc.)
general treatment categories
-articulatory kinematics
-rate.rhythm
-AAC
-intersystemic facilitation/reorginzation
response elaboration training *
clinican encourages client to produce an utterance of choice in response to picture stimuli. clinican then uses reinforcement, modeling, and forward chaining to expand the utterance
-use for aphasia and apraxia
modified version of RET*
focus on increasing language production and techniques to promote speech production. this does not include specfic treatment techniques for apraxic speech production errors
