It is not clear whether gait is learned or is preprogrammed at the spinal cord level. However, once mastered, gait allows us to efficiently move around our environment, requiring little conscious thought, at least in familiar surroundings. On the surface, gait appears to be a very simple task where the lower kinetic chain has two main functions: to provide a stable base of support (BOS) in standing and to propel the body through space with gait allowing the arms and hands to be free for exploration of the environment. Whereas the objective in standing is to maintain a static equilibrium of forces, the objective with mobility is to create and control dynamic, unbalanced forces to produce movement.1 So gait is a complex process that requires control of various neuromuscular, musculoskeletal, cardiopulmonary, and psychological factors to produce controlled instability, making it prone to breakdown.
