Walking instability is not only caused by the cerebellum, but also caused by the following reasons: 1) vestibular lesions in patients with shaking, tilting, or nodding in the sitting position. 2) frontal lobe infarcts, because the frontal lobe has a frontal bridge bundle that is connected to the cerebellum. At this time, if the frontal lobe infarction, there will be walking instability or postural imbalance. 3, walking instability, such as spinal cord lesions, affecting the deep sensory conduction of the patient will also appear walking instability, can not be balanced. 4, diabetes caused by peripheral neuropathy, caused by deep sensory disorders will also appear walking instability, walking like stepping on a cotton-like sensation. 5, anxiety, depression, patients, may also be manifested as Walking unsteady dizziness, and cerebellum has no relationship. Therefore, walking instability is not all due to the cerebellum, but other diseases can also cause walking instability.
