Vestibular training of the inner ear is mainly used to exercise and improve the balance and coordination of the human body and improve the motor ability through weightless training, rotating chair training and other training methods. The main function of the vestibule of the inner ear is to coordinate the balance force of the body, which can accurately feel the change of head position. For example, on a train, closing your eyes, you can feel the car accelerating or decelerating and turning. Inner ear training can be used for people with cerebral infarction and Parkinson’s disease, as well as for infants and young children to learn to crawl and walk earlier. It can be done by spinning in a chair or swinging in a swing or hammock and stimulating the central nervous system through vestibular receptors, thus improving the body’s ability to move. Vestibular training of the inner ear can, to some extent, be able to improve vertigo and improve one’s balance and coordination.
