I think now the vison becomes clear about why you learn the pressure points through kata and "through the system" rather than simply teaching "pressure points". I must have warned people 50 or 75 times on the boards that just knowing pressure points can be very damaging to your uke and fellow practitioners... and hitting points still does damage, even if you can do the resucitations.
Interruptions to the blood supply of a vital organ, or creating a nerve impingment takes a lot of time to "right itself", even if you're awake and "doing fine" otherwise. Most of the strikes take some massage or acupuncture to correct.
Think of it this way... if I give you a revolver loaded with six bullets, spin the chamber, and then shoot you with it and it knocks you out... what is resuciation going to do for you? It'll get you awake... it won't cure the bullet hole, the damage to the tissue, or stop the bleeding... those require "further assistance".
Now, if I create a force application to a specific point in your nervous system or blood supply, what's the difference other than the fact that the force is applied with a knuckle or other "karate weapon" and not a bullet? How about if I use a nunchukun to strike the point?
Besides the obvious answers, of knocking the wind out of someone, or breaking a bone on the inside of them, the answer is that the force has to dissipate itself. If it's a "point strike", it's on specifically designated tissue that has a "purpose" in being hit... meaning it causes a specific reaction, or specific damage. Unattended, it continues to be damaged and doing damage, and simply waking someone up isn't "fixing" anything.
That being said, as a martial artist, you NEED to know the pressure point work... but it isn't something to do once a week in class and then come back next week for a repeat. It's an ongoing study, and a very specific training using your kata or art so you understand it's applications. You need to learn how to stop the pressure point damage BEFORE you start hitting points and screwing up your uke's world.
Getting certified in basic first aid is a good start... as well as good for the dojo. Contact sports create all kinds of injuries by themselves, much less with "intent".
Anyway, Please... don't think that pressure points are "a way to fight"... they are simply a tool. They're very effective, but you have to have the skills to use them, and to use them in a combat situation. An attacker isn't going to simply stick out their neck or turn their head to allow you to hit a vital point... they're going to be trying to hit or harm you... and you have to have accuracy and skill under pressure to make them work.
Like shooting, lots of people can kill a paper target at 25 yards, but can't hit the inside of a barn in a combat situation. Having appropriate skills is necessary, but having combat skills is vital... and acquiring them in pressure point work can be a bit dicey. Your attackers aren't going to walk up and let you hit them with their arms extended, or neck "available"... they're going to be fighting, and you have to "work your way in" to them.
While I have all the respect for kyusho-jitsu teachers in the world, their cheese has slid off the cracker. They need to be concentrating on putting those skills into the arts rather than giving the impression that they are an "all in all" super self-defense. Like karate, it used to be taught in a manner that blended the information into training, but now is taught like "basket weaving" as a separate course and represented as an "end all" method of fighting.
It isn't... it's only a tool.
HAPPY NEW YEAR....
