Study Notes

The gait cycle involves left and right lower extremities.
Double support occurs twice during the gait cycle, totaling about 20%.
The duration of double support varies inversely with the speed of walking.
Stance phase includes the subphases of initial contact, loading response, midstance, terminal stance, and preswing.
Swing phase includes initial swing, midswing, and terminal swing.
Stance phase begins when the foot first makes contact with the ground.
During loading response, the body's impact forces with the ground are absorbed.
Midstance occurs when the body's COM moves directly over the foot.
Terminal swing is the third and final portion of the swing phase.
Some subphases may not occur or may occur with altered timing in the presence of pathology.
