how long on average does it take to regain mobility after a coma?

Question

Suppose you awoke from a four year coma like in Kill Bill , how long would it actually take to start walking again?

Answer 1

it depends on each one,

Answer 2

After a 4 year coma, the prognosis would probably be pretty poor.
Actually, it depends on the reason for the coma, where the site if the lesion is in the brain, and the severity of the damage. Typically, the longer the coma, the worse the outcome will be.
