Different receptors provide different stimulation information to the central nervous system, for example, the visual system provides information on the surrounding environment and the body movement and direction, proprioception provides information on the spatial location and muscular tension state of each part of the body, and the vestibular system provides information on acceleration movement, instantaneous linear acceleration movement, and change of the head position related to linear gravity acceleration, which are comprehensively analyzed by the central nervous system and then put down nerve impulses through the cone beam to adjust the muscle activity to correct the posture of the body at any time to maintain the balance, so that the balance ability of the body must have good muscular tension of the trunk muscles and the lower limb muscles in addition to stable vestibular sensation, and the balance ability is also reduced when the muscular tension is reduced. In addition, the control of the balance ability is not only a comprehensive neuromuscular motion process, but also a motor skill of the human body, and when the perpendicular line of the center of gravity of the human body deviates from the stable base, the perpendicular line of the center of gravity can be returned to the stable base through active reflex activities, so that the control of the balance is realized.
