We have heard about the systems of sensory integration theory, which is divided into seven systems: visual system, auditory, olfactory, taste, tactile, proprioceptive, and today’s vestibular system. For the visual, auditory, taste and smell systems, as we all know, vision is to see, hearing is to hear, it is not difficult to understand, while the tactile proprioceptive vestibular sense, but also with the development of sensory integration theory is slowly realized. So today we will give you a brief introduction to what the vestibule is and how it works for the human body. The vestibular system is not a single organ but multiple organs, and if we talk about it from a medical anatomical point of view, it is particularly complicated and boring, so we will talk about its role more in conjunction with its performance. The vestibular system has many roles, the most familiar is balance, so let’s talk about how the vestibular is related to balance. First of all, if you want to regulate balance, you have to be able to perceive the change of the body’s position in space, which is easy to understand. The receptor that monitors changes in body position and communicates them to the brain is one of the organs of the vestibular system, called the semicircular canal. The semicircular canal is within the cochlea of your ear (so there are often people who feel dizzy and nauseous when their inner ear is injured), and the content of the semicircular canal is rather special, as the semicircular canal is filled with a lot of liquid, and in the middle of the liquid are many cilia cells, which we can imagine as algae floating in the water. This will form a stimulus to tell the brain what position your body is in. The structure of the semicircular canal is very scientific, it has a total of three, and the three semicircular canals are arranged in a three-dimensional form, one is located in front of the back of a located in a horizontal direction, especially three-dimensional. This ensures that no matter which direction your body has changed will be monitored. This is the basis of balance. So what is the specific role of these three half-rules? Generally speaking, the first half-rule is related to the flexion and extension of the body, what is flexion posture, flexion and extension as opposed to flexion, flexion can be said to be the phase centripetal, for example, head down, bending which belongs to the centripetal flexion, while head up, stretching belongs to the extension of the posture. So when you find it easy to lower your head (that is, flexion), always prefer a flexed posture, and want to stimulate the hallux valgus to stimulate the vestibular system, you have to do backward tilting exercises. If there is a problem with the anterior semicircular canal, what would be the manifestation in the child, he may like to hang his head, or like to lie on the table to give you the feeling of sitting without sitting, low alertness, the outside world seems to have nothing to do with me, you see some of these manifestations are mainly flexion posture, right, then to give him some correct and targeted vestibular stimulation you may have to give him something that can induce his body to stretch The main activity. For example, smaller children can do a little airplane game, let the baby lying on the parent’s arm so fly around, to promote his head and crest column stretching, even if the child does not have problems performance can do such games to do early prevention, but also to strengthen the parent-child relationship. For older children you may use more equipment, such as scooters, dragon ball, slide, etc., of course, these devices play a lot, that at this time we are trying to stimulate the front hemiplegia want to induce his stretching posture, so his posture requirements at this time may be prone position, is lying down to play: lying on the skateboard downward, lying on the dragon ball holding the child’s legs back and forth can be downward dive can also be to Up to reach things, lying on the slide down and so on, as long as it can promote his head and crest extension of such activities, can stimulate the anterior semicircular canal, improve his level of alertness, inhibit his poor posture and performance. Contrary to what has been described, if the child is more extended, there are some children who have abnormal muscle tone, high muscle tone that causes them to tilt their heads and hold their chests, usually such a child is particularly alert and not easy to approach. To approach him he may produce a very strong defensive psychology, so then it will affect his emotions and social interaction, in terms of sports may show an unreasonable fear of high, within their ability to the height of the dare not walk dare not run dare not jump. For this type of child to give him targeted vestibular stimulation needs to be the body flexion posture surrounded by stimulation, for example, small babies you can give him in the sheet rocking, the whole body curled up is a state of flexion, like in the mother’s womb, very secure, to reduce his alertness. For older children can put him in the basket, similar to the state of the sheet. This is the first half of the canal training. The posterior semicircular canal is related to the lateral flexion of the body, that is, the shift of the body weight. This also leads to another role of the vestibular system in coordination. If the child shows poor coordination between the two sides of the body, the coordination here is more in the large motor aspects, because some fine motor coordination is related to the cerebellum, he walked up and ran or acted very stiff and inflexible, then at this time want to target stimulation to the posterior semicircular canal should do some activities to promote the body’s weight transfer, such as swing on the side swing, side sway on the ball, active side walk, side tumbling, etc. This can promote the body’s weight transfer, Side rolls and other such activities that promote the body’s center of gravity shift. When it comes to side walk side tumbling can be seen vestibular stimulation is not necessarily the use of equipment, all can cause body posture, postural changes will have vestibular stimulation, just your role in the purpose of stimulating the amount of different sizes, for small children vestibular system stimulation should be soft not too violent. The hair cells in the semicircular canal will receive stimulation during acceleration and deceleration, so the movement should include frequent starts and stops to change direction and speed, swinging and stopping, fast and slow, front and back, left and right. It is not a wiggle and a shake as some parents describe. For children who do not exhibit problems, it can be done randomly as a preventive measure, but for children who exhibit vestibular problems, it must not be a random wiggle. In addition to the semicircular canal, there are two other organs of the vestibular system, the elliptical and balloon sacs. The receptor cells are arranged horizontally in the ellipsoid bursa, so it helps to feel the body move from side to side and the lateral tilt of the head, which is also related to balance and coordination. The ellipsoidal sac is stimulated by swaying from side to side while lying prone on the dalaron ball. The role of the balloon is to feel gravity, back and forth and up and down movements. Problems with the balloon receptors may show sensitivity or retardation to changes in gravity, with the sensitive type disliking jumping and various body gravity changing activities, and the retarded type on the contrary, being restless and seeking stimulation. The receptors are arranged in the vertical plane of the balloon, so if you want to stimulate the balloon, you can do up and down jumping and bouncing activities. However, for sensitive children, it is necessary to do this gradually, while for retarded children, it is necessary to give sufficient stimulation. Finally, for children with vestibular problems, appropriate vestibular stimulation must be accompanied by practical exercises corresponding to the problem, for example, if the vestibular problem causes timidity and fear of heights, the vestibular stimulation should be accompanied by practical exercises such as upward and downward heights, just like muscle training. Vestibular problems are important to prevent, when the child is still young to ensure the safety of the premise must be given enough space to develop independent activities, to cognitive body control body to let the body functions, this is the basis, on the other hand, parents can provide more rich parent-child activities, a variety of lifting, swinging, increase parent-child relationship at the same time, to provide children with a more pleasant emotions, while preventing Vestibular problems can be prevented. For children who already have vestibular problems, parents should not be anxious to find a point that is acceptable to the child to start with, do not be too forced, if necessary, to go to the relevant institutions to do guidance.
