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 forward propulsion of the centre of gravity. A single gait cycle is also known as a stride.

Each gait cycle or stride has two phases:

Stance Phase :The stance phase is that part of a gait cycle during which the foot remains in contact with the ground. For analyzing gait cycle one foot is taken as reference and the movements of the reference foot are studied. It constitutes of 60 percent of the gait cycle. In stance phase the reference foot undergoes five movements:

Swing Phase :The swing phase is that part of the gait cycle during which the reference foot is not in contact with the ground and swings in the air. It constitutes about 40% of gait cycle. It has three parts:
