Document Summary
Whether you have double support or not. All these joints move in every step you take, if not = pathological problem. Pelvic girdle and down = locomotor, what is propelling your body. Lumbo-sacral joint works by itself, everything else works in pairs. For the purposes of our class, we will commonly refer to a stride as being a complete cycle. Step- from heel strike of left to heel strike of right (and vice versa) Stride- 2 successive steps (heel strike from left to heel strike from left) Heel strike defines start and stop of gait cycle. Swing is happening on the left, right is stance. Difference between initial and terminal double limb stance- ex. right leg- initiating double stance, as you go through cycle, right limb now leaving the ground as left is in contact with ground. Right foot initiates double support then terminates double support.
