Balance is a function of the strength and proprioceptive abilities of the musculoskeletal system.

Balance is the state of equilibrium; physically, balance is the condition during which the body's center of gravity is maintained within its base of support. Balance is a function of joint stability, which is influenced by the strength and proprioceptive abilities of the musculoskeletal system. Three sensors drive a sense of balance: the eyes, the inner ear and proprioceptors, or tiny sensors in each joint and muscle that sense the position of a joint relative to the rest of the body. While the eyes, the inner ear and proprioceptors contribute roughly equally to the sense of balance while standing still, dynamic activities, such as walking, running or jumping, engage proprioceptors disproportionately.
