Document Summary
Pre walking movements crawling creeping locomoting with hands held: major limitations the hands are required to move child cannot explore the environment. Walking - dynamic base: width of the base of support changes, wide=immature walking, to, narrow=mature waling average step width start: 230mm, +6 mos. Walking- foot angle amount of toeing in or out degree of toeing- out decreases during first 4 years then stabilizes toeing-in is rare and gait pattern is considered abnormal (only 4. 6% subjects up to 14 years old; engel & Staheli, 1974: what does toeing-out do, widens the base of support, why would immature walkers have greater foot angles, helps them overcome balance issues. Running - requirement adequate lower limb strength to: propel body through air, handle the additional force encountered when the airborne foot strikes the supporting surface improved motor coordination to control the moving lmb.
