Praxis
|
refers to the ability to produce purposeful learned movements.
|
|
Apraxia
|
refers to disturbed ability to produce purposeful, learned movements despite intact mobility usually as a result of Left Hemisphere damage
|
|
Limpmann described three forms of Apraxia
|
Limb kinetic, ideational, and ideomotor
|
|
Limb kinetic
|
loss of kinetic memories for one limb (this form of apraxia is rarely diagnosed)
|
|
Ideational
|
higher level disorder in which the individual movements are intact, but the execution of complex sequential movememts with objects is impaired (e.g. Patient tries to smoke the match instead of the cigarette) some investigators consider ideational apraxia a severe form of ideomotor. (complex movement patterns)
|
|
Ideomotor
|
disturbance in the ability to produce learned movements despite intact mobility, sensation, coordination, and comprehension.(disturbing the timing, sequencing, occurance.
|
|
Apraxia of Speech
|
articulatory disorder that results from difficulty programming the positioning of speech muscles and in sequencing muscle movements for volitional production of speech.
|
|
What type of aphasia tends to co-occur with aphasia
|
ideamotor
|
|
Apraxia is what type of disorder
|
Motor Speech
|
|
Geschwind defined ideomotor apraxia as..
|
inability to to program, sequence, and execute purposeful gestures, either on command or in imitation, subsequent to brain damage.
|
|
Ideamotor manifests itself into two forms
|
Limb and Oral
|
|
Limb Apraxia
|
involves movements of nonparalyzed fingers, wrist, elbow, and sholder.
|
|
Oral Apraxia
|
involves movements of facial, oral, and respiratory structures.
