A (bipedal) gait cycle is the time period or sequence of events or movements during locomotion in which one foot contacts the ground to when that same foot again contacts the ground, and involves propulsion of the centre of gravity in the direction of motion.
A gait cycle usually involves co-operative movements of both the left and right legs and feet.
[4] The swing phase corresponds to the single-limb stance of the opposite leg.
The stance and swing phases can further be divided by seven events into seven smaller phases in which the body postures are specific.
Stance Phase: Stance phase is that part of a gait cycle during which the foot remains in contact with the ground.
