In context
Reflex-hierarchic models hypothesize that motor development is based on what?
CNS maturation
reflex hierarchic models says movement is
Motor development is Wired in brain.
First movements reflect low level - brainstem - before cortical
Masgutova Neurosensorimotor Reflex Integration (MNRI) method assumes what?
motor reflex patterns play a subordinate role in the maturation of more complex motor reflex schemes (e.g., rolling over, sitting up, crawling) and that integrating reflexes can improve functional movement
The postural mechanism includes several strategic components:
•Muscle / postural tone

•Emergence of righting, equilibrium, and protective extension reactions

•Developmental integration of early, primitive reflex movement patterns

•Intentional, voluntary movements against the forces of gravity

• combine movement patterns in the performance of functional activities
Instead of freely moving and exploring the world, as children with a normally developing sensorimotor system do, children who have CP may rely on ___ as their primary means of mobility
primitive and automatic reflex movement patterns
Muscle tone
the force with which a muscle resists being lengthened
it can also be defined as the muscle's resting stiffness.
Muscle tone is tested by an occupational therapist:
passive stretch of the muscle from the shortened to the lengthened state
