    • no recip arm swing
    • no trunk and pelvic rot
    • 4-6 months after walking starts
  17. toddlers (1-3 yo) - their center of gravity compared to ours? its effect on their gait?
    it's higher due to their big heads and chests, and it makes the walk w wider base of support
  18. how much time do we spend in single leg stance? how much time do toddlers spend?
    • us - 39% per leg
    • them - 30% per leg-- so they spend more time in double leg stance

    ratio for us
    ratio for toddlers
    • us: 1.57
    • toddlers: 1.3

    • arm - 4yo
    • hip - 3yo
  22. how much reduction in velocity, how often, after what age?
    2.5-4.5% reduction every 10 yrs after 20 yo
  23. gait changes after age 62?
    • decrese in unilat stance time
    • decrease in PF and DF, but esp DF
    • decrease force in PF

    contralat leg is up, moving forward
