From my security days: Taijiquan redirection.
A person in the ER, brought in on a mental health warrant.
He came out of his room and said he was leaving, and that there was nothing I could do to stop him.
He charged at me, i put my hands out a bit, when he touched them I redirected his force into the wall behind me.
He slid down the wall and I then restrained him
He said.... "OK. I'll go back to my room now"
I said.... "I already know that."
He got up and walked back to his room
had no more problems with him the rest of the night
I was rather surprised that it work and came as naturally as it did. I used no force at all. Just redirected his.
Most of the rest of the issues I had when working there were handled by qinna, and that was really not all that surprising...
