will she wake up again?

In my experience a colonist will only wake up if brain injury is 3/10 or higher, any lower and they will not wake up.

When movement speed is low enough, something can be permanently incapacitated. For example, a person missing one leg (0% movement).

From what I've seen happen to centipedes, though, the speed where incapacitation starts is actually higher than 0%. If it's between 20% and 30%, that would explain that. Brain at 2/10, 20% movement speed, incapacitated (no more useful than a colonist with one leg). Brain at 3/10, 30% movement speed, not incapacitated (just really slow).
