Cerebellar plays a very important role in central nervous system . It is mainly responsible for the regulation of posture, limb movements, head and eye coordination, etc. The cerebellum is a comparison between the incoming sensory information and the outgoing of motor information. When an action is to be completed, the active action commands issued by the brain and many sensory signals when actually performing the action will be transmitted to the cerebellum. If the action required by the brain does not match the sensory signals generated during actual execution, the cerebellum will provide correct feedback control to the action path, so that the action can be corrected in time before completing the action as the correct mode.
In addition to correcting the ongoing movements, the cerebellum can also correctly adjust many reflex effects before generating the movements, so that the limbs can reach the optimal state of preparation before performing the movements. In addition, the cerebellum has an extremely important function, which is movement learning, which can design an appropriate active action mode based on previously experienced sensory and motor information and store it here. If the cerebellum is damaged, the actions you have learned will not be activated again. Therefore, each time you do the movement, it will be considered as learning a new movement again, so there will often be incongruence of movements.
Common functional injuries in patients with cerebellar functional injury include: unstable posture, equilibrium disorder, gait disorder, poor motor control, abnormal limb movement coordination, muscle tone too low, muscle strength loss, and abnormal eye movement control. Differentiate by physiological function damage of the cerebellum. If the cerebellum loses the comparison function between sensory information and motor information, patients usually experience poor movement distance. Such patients will need to spend a lot of time practicing various movements, and the effect of decomposition movement training will be better than a complete set of exercises. During the training process, even if the cerebellum loses the ability to automatically correct errors, as the movements are repeated, the patient will be able to learn to actively correct movements, or other neural tissues in the central nervous system may be shaped to have the ability to automatically correct movements; if the cerebellum loses the ability to learn movements, the patient's movement learning ability will be quite limited, and the progress of treatment will be very slow. However, until now, there is no document to prove the degree of impact of impaired movement learning ability in patients with cerebellar injury.
Patients with cerebellar function impairment, like other neurological patients, will experience many neurological symptoms, and these neurological symptoms require the intervention of physical therapy to promote the relief of symptoms and the recovery of functions. Although the data on the efficacy of physical therapy intervention in patients with cerebellar functional injury are quite limited, most of the research results show that physical therapy does have certain therapeutic effects on patients with cerebellar functional injury.
Clinically, most patients with cerebellar function injury are diffuse cerebellar damage, and most of these patients have problems of balance and gait disorders. Balance ability plays a very important role in many daily life activities. Once a balance ability disorder occurs, it will usually affect the independence of their walking ability and daily life. Therefore, for patients with cerebellar function injury, promoting the improvement of their balance ability is often an important part of the rehabilitation plan.
