Would this work? (good read i'd say)

[mourning_]

hey everyone i just got this book 'kill or get killed' great bok. it shows a technique where u sneak up on opponent. (obviously this is NOT self defense, but the technique could be used in self defense possibly) anyways basically you simultaneously hit your opponent in both ear/eardrums with a knife hand? (sorry i forgot what they called it, but its a well known strike) so you strike the eardrums simultaneously and its supose to cause blackout by cusuhing both eardrums.

whats your thought on this? would it work effectively?

if you guys like it, maybe i can post some more stuff for ya =D

Is this the book written by Rex Applegate? It should work effectively, given that his system of fighting (I dont think it has a name, but it is based upon another art called Defendu) was enhanced with feedback from OSS operatives (OSS = wartime precursor to CIA) who used his taught techniques in World War II, so field testing has played a part in it's development.

Is it called shoto ???

Well it might work , but why risk it , if you are going to sneak attack him , use a weapon or simply brake his neck

A flat hand slap to both ears may work, except to perform such an act, you touch upon their peripheral vision. Also, you are required to get close BEFORE attacking, not to mention doing it from behind them. I mean, in a perfect world, sure... it would work, but we don't live in a perfect world.

Nowadays, higher level security personnel are taught to keep their back to the wall while on sentry, and to turn about repeatedly while on patrol. So, if your target isn't a little old lady waiting at the bus stop, such a technique has limited applicability.

If your question is whether, anatomically, it could work, the answer is yes, and no. Basically, the task of keeping us 'upright' is not a simple one and the human body has devised some creative ways of ensuring we maintain our balance on those two stumps we call legs. The semicircular canals behind the cochlea are what manage your equilibrium, through an ingenious xyz series of canals partially filled with fluid. Inside the canals, there are little hairs that act as sensors. When the fluid moves about, it moves the hairs (cilia), which the brain interprets as motion and thus your body attempts to compensate for said motion.

By striking the ear with a flat hand, you quickly force air to pound against the tiny bones and ear drum that serve to transfer motion to the cochlea, which is interpreted by the brain as varying sound waves. A concussion of air, compressed and thrust into the ear canal, essentially shoots a huge wave of sound through the cochlea (not quite, but close enough). A sufficient impact could generate a reverberation, an echoed wave, to impact the semicircular canals and thus cause the fluids in there to go wild for a short period.

This combination, with the likely possibility of causing the ear drum (tympanic membrane) to tear, or the tiny bones (hammer, anvil and stirrup) in the ear to break, can significantly disorient an adversary.

Now, here are some of the 'no' parts. If what you mean by knife hand is what i think you mean, and what y2_sub referred to as shuto, then such a strike is not necessarily aiming to impact the eardrum, but the trigeminal nerve root. A sufficient impact could cause the nerve to send an overwhelming signal to the brain stem, which could cause one to lose consciousness.

However, such an impact must be very hard, and it is not likely that sufficient force could be garnered by performing simultaneous inward shutos (shuto-uchi) at a target above your own shoulder level. In truth, there's no need to strike both sides of the head if the goal is to impact the trigeminal nerve root. Only one side needs to be targeted, which would allow for sufficient force to be generated from a single direction.

Also, the knife hand technique is not really a good one to use against the ear, if the goal is to impact the eardrum or cause a concussive wave to jar the semicircular canals. The edge of the hand simply doesn't cover enough area to 'trap' air into the ear canal, thus too much emphasis on accuracy would be required, which would take away some of the power necessary for any effect to occur.

i believe the strike was more with the palms of the hands. not so much a knife hand. sorry it was late last night, and i could tell you exactly what it was, but i did not bring the book to school...wouldn't want to get it taken away but yes i know the scenario would be rare but i was wondering more about the strike itself. so when the strike is performed, is it supose to be a strike, or a strike and then hold until they go down? you said air is supose to be trapped, so thats why i asked. (im going have to read those posts several times to understand them btw)

also are you an ear doctor!?!?

jk, great info

when i get home i'll try and post exactly what it says, maybe that might help what we're looking for here.

Sure won't do the guy any good, but unless YOU can test it, multiple times on multiple people, don't make any assumptions about exactly what will happen.

Many, many myths exsist in the martial arts world about "When you do this, .... happens". If you can't personally test it, never assume that it will happen as advertised any more then thinking that "belly zapper" thing you saw on an infomercial will give you a six pack by electricuting your belly while you lie on the couch and eat nachos.

it says the 'simultaneous boxing of the opponents ears, will rupture both eardrums, causing a blackout. (thats the caption. when it describes it in text it says 'ear concussion blow:...you can rupture both ear drums by cupping both hands and simultaneously striking them against his ears. A type of concussion will occur that causes the victim to become 'slap happy' and will make him an easy target to dowith as you will' remmeber its form the rear and im not so much worried about the scenario more so the strike.

so hopefully i've cleared things up and yes it is by Rex Applegate.

so any thoughts?

ps - good book.

I don't see how, but I'm no expert with this so it's possible I guess. Personally, I'd just choke them out (5 seconds max- and when they go out you're conveniently already holding them) or just hit them to knock them out.
