Balance is the ability to remain upright and move steadily by evenly distributing your body's weight. It is maintained through a complex combination of sensorimotor control systems, which include sensory input from vision, proprioception, the body's ability to sense its movements and position, the visual and vestibular components system in the inner ear which manages motion, equilibrium, and spatial orientation, proper incorporation of sensory input, and motor output to the eyes and muscles.
