I know a gentleman who had a brain stem stroke with resultant quadriplegia. 8 years passed, then he sought alternative help. Within 1 week of having a spinal tap infusion of placental stem cells he was moving his left arm and hand to his mouth. A month later he was moving 3 of 4 extremities. Mind you, he was not dancing a jig, but after being quadriplegic for 8 years, for him it was huge to be able to put food in his own mouth.
