Expected motions during normal gait Flashcards
At heel strike, what should the hip be doing?
Should be flexed and internally rotating
At heel strike, what should the knee/lower limb be doing?
Fully extended, lower limb beginning to internally rotate
At heel strike, what should the ankle be doing?
Dorsiflexed, but slowly plantar flexing
At heel strike, what should the STJ and midfoot be doing?
STJ will be supinated, while the midfoot will be pronated about the oblique axis and supinated about the longitudinal axis
At loading response, what should the hip be doing?
In a flexed position, but extending
At loading response, what should the knee/lower leg be doing?
Knee should be flexing, and the tibia should be internally rotating
At loading response, what should the ankle be doing?
Plantarflexing
At loading response, what should the STJ be doing?
Pronating
At midstance, what should the hip be doing?
Externally rotating and extending
At midstance, what should the knee/lower leg be doing?
Knee is flexed but extending, and the lower leg is externally rotating
At midstance, what should the ankle be doing?
Passively dorsiflexing as the stance leg shifts over the foot
At midstance, what should the STJ be doing?
Pronated through a majority of this phase, but will begin supinating towards neutral towards the end. This converts the foot to a rigid lever for toe off, a process called resupination
At midstance, what should the midfoot be doing?
The calcaneocuboid joint is locking to stabilize the rearfoot on the forefoot to provide a rigid lever for toe off
At heel lift, what should the hip be doing?
Extending and externally rotating
At heel lift, what should the knee/lower leg be doing?
Flexing to allow for ground clearance in next phase
