The most important lesion of cerebellar atrophy is that it causes coordination and balance disorders. Rehabilitation training methods include the following 2 aspects, which are as follows: 1. Coordination training: many of the coordination functions are very fine, and it is necessary to rebuild the hand function, and to carry out coarse grasping such as lifting an umbrella for a long period of time, as well as fine movements such as undoing buttons, clipping fingernails, holding paper or money; 2. Balance training: it is important to build up the balance from the coarse balance, and to carry out the related training from a large area to a small area, from a low center of gravity to a high center of gravity, and from a static to a dynamic one, and it is necessary to tighten the training around these elements.
