Gross Motor 1yr+ Flashcards
Gait cycle characteristics (walking)
50% phasing btwn legs - each leg spends equal time in swing/stance.
DL support & SL support.
Consistent across lifespan.
Independent walking/standing is achieved by…
9-18mo
Mature walking pattern is achieved by…
3.5 to 4 yrs
Characteristics of early walking
Short steps - very little leg/hip ext. Flat feet, toes out. Wide BOS. No trunk rotation. Arms in high guard (eventually progresses to mid guard, then low guard).
Rate controllers in early walking (what prerequisites are required for walking)
Adequate motor control & system maturation. Adequate ROM. Adequate strength. Appropriate bone structure & body comp. Intact sensory systems.
Walking: pelvic rotation
13mo
Walking: narrower BOS
17mo
Walking: synchronous arm swing
18mo
Walking: heel to forefoot strike
18mo
Walking: backward walking
18mo
Walking: SL support time increases
1 to 2.5yr
Walking: velocity increases
1 to 3.5 yr
Walking: advanced walking achieved
3-4yr
Walking: rhythm & coordination improve until
5yr
Characteristics of proficient walking
Increased stride length. Heel to forefoot. Narrower BOS, less toe-out. Pelvic rotation. Improved balance, less fwd trunk lean. Oppositional arm swing w/ leg movements.
Gait cycle characteristics (running)
Still 50% phasing btwn legs.
Flight period where both feet off the ground.
Characteristics of early running
Starts 6-7mo after child begins to walk.
May involve characteristics of early walking.
Limited leg ROM during flight phase = short strides.
Arm swing to accompany trunk rotation.
Rate controllers in early running
Task constraint - do they need to have the change in speed btwn walking & running?
Individual constraint - strength, balance.
Development of running
Improved coordination & strength.
Growth.
Changes continue thru childhood & adolescence.
Many adults exhibit inefficient running patterns.
Running: speed increases
29-30mo
and
37-38mo
Running: balance/coordination improve
45-46mo
Characteristics of proficient running
Stride length increases as greater force is used. Elimination of lateral leg motion. Heel strike or flat foot strike during extended running. Narrower BOS, no toe-out. Knee flex on supporting leg. Trunk rotation increases. Slight fwd trunk lean. Oppositional arm swing.
Stairs: walking up with support from railing
15-16mo
Stairs: walking down with support from railing
17-18mo
Stairs: walking up with no support
23-24mo
Stairs: walking down with no support
25-26mo
