Which apraxia is an Inability to make precise or isolated movements with fingers, hand, arm, or leg, with Inaccurate or clumsy distal limb movements? Limb-kinetic apraxia
Which apraxia is difficulty with the "how to," where the pt is unable to imitate another person’s gesture, to perform the appropriate action in response to a visually presented object, or to carry out a movement using the actual object? ideomotor - can still perform action without thinking about it - affects timing, sequencing, amplitude, configuration and limb position in space
Which apraxia is difficulty with the "what to do," where the pt is unable to create a plan for a specific movement? ideational
What are 4 other types of apraxia? Dissociation (cannot gesture normally to command but can use tools/objects); Conceptual (cannot recall use of tools/objects); Bucco-facial (unable to move face on command); Speech (unable to plan or coordinate speech)
What system is affected with apraxia? The praxis system: 1.brain regions that are involved in taking in processed sensory input 2. obtaining stored information about tools, gestures, and actions 3. translating these into a motor output
What are some differential dx's from apraxia? Rule out comprehension deficit, muscle weakness, sensory impairment, tone abnormality, other movement disorder
How would you Dx apraxia? present a tool and ask pt what it is or how to use it or ask pt to copy gesture
What factors affect prognosis of apraxia? size of lesion, presence of associated disorders, health and attitude of pt and time of post-onset - pts with posterior lesions have poorer prog than anterior lesions
What are some implications for PT with apraxic pts? become dependent with ADLs, useless limb can become clenched/painful fist, high risk of falls, nutritional deficits - refer out (esp OT)
What neuro condition is a recognition deficit affecting a single modality where cognitive abilities in other areas are preserved? Agnosia - caused by stroke, dementia, neuro disorders, brain infection, head injruy (esp occipital or parietal)
