Praxis and motor planning

Praxis

Ability to conceive of, plan, and carry out unfamiliar motor actions (ideation, motor planning, execution)

Ideation

First stage of praxis; generating the concept of what to do

Motor planning

Organizing and sequencing movements into an action; impairment is dyspraxia

Dyspraxia

Impaired motor planning with typical neurology; trouble with new, unfamiliar, or multistep tasks

• impacts gross and fine motor movements

• also presents with language difficulty and difficulty with thoughts and perception

• uncoordinated and awkward movement patterns

• appears clumsy

Somatodyspraxia

Ayres term for dyspraxia from poor tactile, proprioceptive, and vestibular processing

Feedforward

nticipatory planning before movement

feedback

adjusting during/after using sensory info; DCD involves deficits in both

apraxia

• deficit in learned motor movements

• unrelated to weakness, incoordination, sensory loss, or lack of comprehension

• typically it is associated with brain injury

• loss of coordinated motor movements that were previously learned
