Gait: stance phase

What are the five subdivisions of the stance phase?

Answer:

1. Initial contact: instant foot contacts ground

2. Loading response: from initial contact to lift of contralateral extremity from ground (wt shift)

3. Midstance: from lift of contralateral extremity to when ankles of both extremities are aligned.

4. Terminal stance: from ankle alignment in the frontal plane to just prior to inital contact of the contralateral (swinging) extremity.

5. Preswing: From initial contact of contralat extremity to just prior to lift off of ipsilateral extremity (wt shift)

Stance phase makes up 60% of gait cycle.
