Through these efforts, the basic components of the gait cycle, its phases, and subphases have been identified, defined observationally, and linked to their kinematic, kinetic, and muscle behaviors. More in-depth analysis has revealed combinations of subphases that define the operational features of gait—organized components of the gait cycle reflecting functional features that achieve important operating objectives of the locomotion system. These objectives include advancement of the body’s center of mass by means of swing phase and stance phase propulsion mechanisms, foot–floor clearance mechanisms of the swinging limb, and antigravity stability mechanisms that operate during loading of body weight and the subsequent period of single limb support. Common gait deviations have also been analyzed in terms of how they relate to the larger context of the operational features of gait, providing insight into rehabilitative strategies that can best address operational features gone awry.
