How to Perform the Vulcan Nerve Pinch. The Vulcan Nerve Pinch can quickly render an unsuspecting opponent unconscious; the pinch has its roots in martial arts. Although the original Vulcan Nerve Pinch is impossible for humans to perform, here is a version that you can utilize, although its effectiveness is questionable.
How to Perform the Vulcan Nerve Pinch
Locate your opponent's radial nerve. Found 2 inches below the elbow joint on top of the forearm, the radial nerve helps to control movement of the arm.
Press your thumb or knuckle into the radial nerve. By activating the radial nerve, you can temporarily paralyze your opponent's arm to give you time for the next step, activating the brachial plexus tie-in.
Locate the brachial plexus tie-in. The brachial plexus is about 2 inches below the shoulder near the corner of the pectoral muscle and about one inch above the armpit.
Activate the brachial plexus tie-in, using your thumb or index finger knuckle while still applying pressure to the radial nerve. This deadens the subject's arm to allow you move in closer.
Apply pressure or a chop to the brachial plexus origin, which is found at the base of the neck on either side, directly above the collarbone. This is where the carotid artery and several nerves run. Activating it through pressure can result in unconsciousness.
Although this works in a TV program, it's not likely to work in the real world. As a martial arts expert once said, "If you're depending on this move to save you in a street fight, you deserve to get beat up."
