Purpose of initial contact
Prep. for weight acceptance
Period of double limb support
Makes up 0-2%
Purpose & length of loading response
Quads do most work here Shock absorption Stability Forward progression (heel rock) 0-10%
Purpose and length of midstance
Continue forward progression
Trunk/limb stability
10-30%
Purpose and length of terminal stance
Forward progression
30-50%
Purpose and length of preswing
Double limb support Prep limb for swing Need lots of toe extension Supination leaps w push off 50-60%
