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.
