For a long time, due to the influence of the view that “nerve cells cannot be regenerated after death”, academics have always believed that it is difficult to recover after serious neurological injury. The practice of clinical rehabilitation medicine confirms that neurological diseases and post-injury functions can be recovered; the brain is plastic, and brain functions can be reorganized after brain injury. Many patients with brain injury have recovered their damaged neurological functions and even returned to work after rehabilitation, and there are many such examples. Therefore, mastering the principles of rehabilitation is related to how to make the best recovery of neurological injury.
