Normal Development thru Newborn & Gross Motor Development Flashcards
what mechanics does a new walker have
flat feet toes out wide BOS short steps no trunk rotation high guard arms progressing to middle and low guard
rate limiters to walking
reciprocal leg movements
strength to support on single limb
balance
what are some proficient walking patterns
absolute stride length increases heel strike develops BOS narrows pelvic rotation decreased forward trunk inclination arm swing
when does running develop in kids
6-7 months after walking emerges
in the maturational theory, how does development occur
- in a cephalocaudal direction
- in a proximal-distal direction
- development of one motor skill leads to the other
in the maturational view, how do motor skills develop
- from gross to fine
- from reflexive to voluntary
- total response before localized response
- cephalic control before caudal control
dynamic systems theory covers what
the lifespan
what is dynamic systems theory
assumes that the individual functions as a complex, dynamic system comprising many subsystems and that there is an innate organization that occurs between complex particles that is directed by no one system
how do movements emerge in the dynamic system theory
based on the childs internal milieu, external environment and the motor task to be completed
what is the normal development timeline
physiological flexion antigravity extension antigravity flexion lateral flexion rotation
weight bearing-weight shifting is what
stability in postures permits effective weight bearing and weight bearing experiences assist in the development of stability
to move with control what must happen
weight shifts must occur
weight shift occurs how
one body part stabilized simultaneously with the other body part being unweighted enough to move
rotation-dissociation
rotation requires balanced control of flexion and extension and dissociation between body segments
what is dissociation
breaking up the mass pattern, it is the ability to separate movement in one body part from associated movement in another
