Observational Gait Analysis

"Normal human gait repeats a basic sequence of limb motions that serve to progress the body along a desired path while retaining weight bearing stability conserving energy and absorbing the shock of floor impact. A gait cycle is defined as the time from heel strike to the next ipsilateral heel strike. The most common method of dividing the gait cycle is into stance and swing. Stance is the entire period the limb is in contact with the ground and swing begins when the foot comes off the ground.
