Document Summary
Characteristics of initial walking gait > small steps, legs wide, toes pointed outward, knees slightly bent, walk on tip toes or at-footed, arms lifted, regains balance after each step. Elementary: increased stride length, smoother pattern, improved postural control, initiating heel-toe pattern, arms down (no swing) Mature: re exive reciprocal arm swing, de nite heel-toe contact, double knee-lock pattern, narrow base of support. Running > complex skills than walking due to faster stride speed, higher knee lift, larger stride length, ight phase, increased power generation, higher impact on body. Development of running (6 months after walking a child will attempt early running patterns) Arms held in either a middle or high guard position. Arms move to the sides as opposed to back and forth. Elementary: increased stride length, close to ight phase, arm swing increases. Mature: distinct ight, optimal exion (thigh parallel), maximal extension of support leg, arms (90 degrees), pro cient (5 years old)
