The Gait Cycle is a sequence of neurologic and mechanical events, leading to the synchronized pattern of movement that moves us through the world. In its most general form, the gait cycle is divided into two phases: stance and swing. These phases refer to the action of the limb that is either in contact with the ground and providing support (stance), or in the air and preparing for the next step (swing). Each phase is further broken down into subphases, based on the action of the various osseous and muscular groups causing movement. The gait cycle is the time interval or sequence of movements occurring between two consecutive initial contacts of the same foot. To evaluate the gait cycle, you have to describe what happens in one leg, and then duplicate the observations with the other leg.
