mobility control Flashcards
diaphyses are almost ossified at
birth
epiphyses are cartilaginous at
birth
at birth the acetabulum covers less than
1/2 of the femoral head
acetabulum depth increases to age
8
rolling is a prerequisite for
supine to sit or supine to stand
roll sidelying to supine
1-2 mo
prone to supine
4 mo
supine to sidelying
4-5 mo
supine to prone
6-8 mo
development of segmental rotation rather than log rolling
9 mo
most children will walk between
9 and 15 mo
gait is fully mature by age
7
attributes of mature gait
stability in stance sufficient foot clearance appropriate pre positioning adequate step length energy conservation
determinants of mature walking
duration of SL stance walking velocity cadence step length ratio of pelvic span; ankle spread
