____ is marked by poorly formed letters, with copying impaired and no case effect, with intact oral spelling. Common in Broca’s, but can occur in isolation.
Apraxic agraphia
____ is marked by poor spacing on page consistently on one side or the other and could omit beginning or ends of words.
Spatial agraphia
What is a very popular agraphia approach?
Copy and Recall Treatment (CART) can be done as a home program, choose meaningful words, and make them copy 5 times, if the get it write can move on if not, repeat. can practice prompts at home.
____ means that it doesn’t have to have a recipient of the gesture (learned movement). (Salute, hitchhike, wave goodbye). Less degrees of freedom, but more abstract. Some evidence this is easier for individuals with limb apraxia.
Intransitive gestures
What is the best way to test for limb apraxia?
ask for pantomime use of tools in absence of tool
Name 3 are some limb apraxia testing tasks:
wave goodbye, hitchhike, salute, use a saw, use a toothbrush, drink from a cup, put salt on food, use a key to open a door, use a screwdriver, shoot a gun, use a comb, drink from a glass, use scissors, flip a coin

What should the clinician remember when testing a patient with suspected limb apraxia with objects?
be as non-directive as possible:don’t hand them the handle first or put them in the hand as if to use, let them locate the useful part
Just like with speech, individuals can repeat gestures without meaning. T/F
true
_____ has been definied as a disorder of skilled movement that cannot be attributed to other causes of motor impairment, intellectual impairment, impaired comprehension, inattention or uncooperativeness.
Limb apraxia
Why should we care about limb apraxia? 3
1 it’s common
2 it’s persistent
3 it’s problematic (Difficulty with tools - how can the pt cook?)
How does semantics work with limb apraxia?
need to understand action semantics: how we use tools
What are the different inputs for the action output system? 4
audiotry/verbal
visual/gestural
visual/object
tactile
What is the difference between transitive and intransitive gestures?
transitive gestures require a direct object (hammer, scissors, etc.)
What do you need to assess besides pantomime-to-command with limb apraxia? 3
visual tool use
imitation tool use
tool object or tool gesture association
___ is a loss of deftness or fine motor control; inability to connect innervations of independent units. Cannot pick up the penny off of the table.(Type of Limb Apraxia)
Limb kinetic apraxia
____ is a failure with the “production” aspects of skilled movement: selection, sequencing and spatial organization of movements. (Most common form of limb apraxia)
Ideomotor Apraxia
Name 3 spatial production errors that could be found in limb apraxia
wrong limb/joint movement; external configuration; internal configuration; body part as tool; concrete object
Name 3 temporal production errors that could vbe found in limb apraxia.
amplitude; sequencing; occurence; delay
____ is a deficit in higher order abstract actio nand goal planning.
Ideational apraxia
____is a deficit in conceptual knowledge associated with tool or object use.
Conceptual apraxia
What type of content errors might be found in limb apraxia? 4
1 no content
2 related content
3 unrelated content
4 perseveration
What are methods for rehabilitation of limb apraxia? 2
Management through accommmodation
Treatment though direct application of aid to the deficient behaviors (Better with practice, train with gestures, self-verbalization, provide as much contextual information as possible)
