When we treat paralysis, we input stimulation to body security, not to brain.
In another word, it is a body cancer.
When brain get radical damage, the brain activate body security too much.
So most of brain strokers have a brain that working too much.
In this moment, they need to calm down this brain, or all rehabilitation and medical care get no work.
How we calm down this sensitive brain?
We input illusional stimulation to body censors that they feel as unnatural.
With this stimulation, body censors must change their reactions.
So cognitive functions and body linkage get better.
