The unstable walking of young people is actually a manifestation of human balance disorder. Under normal circumstances, human balance maintenance relies on the three systems of vestibular system, visual system and proprioceptive system to maintain together, which is called balance triad. Any part of the balance triad or any part of the pathway linked to the center is affected by physiological stimuli or pathological factors, objectively it will manifest as a balance disorder, subjectively it manifests as vertigo and dizziness, so wake up vertigo walking unsteadiness to find the cause from the balance triad, specifically as follows: 1, vestibular system problems, common diseases of the vestibular system, such as vestibular neuritis, Ménière’s disease, Otoliths, Hunter’s syndrome, large vestibular conduit syndrome, superior hemianopia, etc. can cause vertigo and unstable walking; 2, problems in the visual system, vision loss, myopia, hyperopia, strabismus, such as looking at cell phones, computers for a long time dizziness, or walking in the dark and walking in a place with light feel different limb balance; 3, proprioception, proprioception refers to the body’s deep sensation, and epidermal touch, warmth, pain, superficial sensation, The deep senses are located at the joints, tendons and muscles of the body, and lesions in this place or problems in the neural pathways connected to it can also cause unstable walking and dizziness, such as arthritis, myasthenia gravis, lumbar disc herniation, etc. can cause unstable walking; 4. The symptoms of vertigo and unstable walking can also be associated with cerebellar and brainstem lesions, stroke, dorsolateral medullary syndrome, or infarction of the anterior inferior cerebellar artery.
