Functional characteristics: In skateboarding activities, the vision will send a large number of information to the central nervous system, the inherent sense will make the cerebellum more awake, directing changes in muscle tension. The movement between the cerebrum and the cerebellum can have a powerful and correct integration effect, so that the overall sensory integration operation of the human body has a positive development. The main sensory inputs are: 1. Vestibular proprioception:Crawling on a skateboard in a prone position will produce a lot of stimulation to the vestibule, the sense of gravity when lying prone and the tension caused by the movement of muscles and joints during travel. 2. Touch sensation: the touch and pressure sensation of the body in contact, and the skin and muscle sensation when the hand is in contact with the ground. 3. Vision:The special stimulation to the vestibular balance organ and the direct effect of the strong proprioceptive information produced by the strong contraction of the neck and back muscles on the medial accessory bundle of the oculomotor nerve have an excellent effect on the stability of eye movement and contribute to the formation of a good self-visual space. The sensory integration pulley can stimulate the vestibule, the body, and open the neural pathways of the brain. 1. When gliding on the pulley, vestibular receptors will be strongly stimulated. A series of vestibular stimulation inputs can open many nerve channels in the brain, which will activate many reflexes in the body. 2. In the process of moving the body, a large amount of visual information is input, which contributes to the formation of ontological sense and visual space.
