The cerebellum becomes the coordination center to maintain balance and muscle tension through complex regulation and feedback mechanisms, and also enables the body muscle system to complete fine technical movements. The cerebellum, like a computer, can scan and coordinate sensory afferent and regulate motor efferent. Functional division of cerebellum: 1. Basic part: keep balance. Middle part: related to hearing and visual functions. It is not clear what symptoms will appear during the lesion. 3. The front part mainly controls the posture reflex and the coordinated action of walking. 4. The main function is to control the skillful random movements of the ipsilateral limbs. The functional orientation of cerebellum, the undivided parts on both sides of the body (trunk) are dominated by the undivided parts on both sides of the cerebellum (vermis), the front end of vermis dominates the muscles of the head, and the back part dominates the muscles of the neck and trunk. The muscles of the limbs are dominated by the ipsilateral cerebellar hemisphere, with the forelimbs above and the hind limbs below.

The symptoms of cerebellar dysfunction are as follows: 1. Ataxia: due to the lack of cerebellar accommodation, the patient is unstable, trembling, and the gait is unstable. It is a drunkard gait: when walking, the legs are far apart, swinging from side to side, and the upper limbs are flexed and stretched forward, like falling. It is difficult to stand on two feet. Generally, you can't stand on one foot, and opening your eyes or closing your eyes has little effect on the stability of standing. Abnormal handwriting is also a manifestation of ataxia of arms and hands, with irregular handwriting and trembling strokes. Generally, writing is too big, and tremor and paralysis are mostly too small.

Regular participation in sports activities and strengthening endurance and strength are the most important means to improve balance ability. On the basis of improving the overall physique, people can also carry out some auxiliary exercises that help improve their balance ability. Auxiliary exercises to enhance balance ability include: ① Walking in a straight line on the flat ground. Young people can practice on the balance beam or something similar; ② Stand in a straight line with the toe of one foot against the heel of the other; 3 Put your hands on your waist and stand with your eyes open or your eyes closed. ④ Walking or standing on a thick mat; ⑤ Practice Tai Ji Chuan.

Please note: when the elderly do balance exercises, they must take protective measures to prevent falling!

It needs to be emphasized again that because the effect of simple auxiliary balance exercise is very limited, improving the overall quality of the body is the fundamental measure to maintain good balance ability.

Wish you success!
