Leonard Nimoy, who portrayed the Vulcan science officer Spock, conceived the maneuver in the early days of the original Star Trek series. The script for “The Enemy Within” stated that Spock "kayoes" Captain Kirk’s duplicate, but Nimoy—who opposed the Vietnam War and supported Eugene McCarthy—felt that such a brutal action would be undignified for a Vulcan. He therefore invented an alternative by suggesting that Vulcans have the ability to project telepathic energy from their fingertips similar to "the Vulcan Mind Meld", which, if applied to a nerve cluster correctly, could render a human unconscious. Allegedly, the director of the episode didn't understand the idea when Nimoy explained it to him, but William Shatner understood immediately and reacted in exactly the way Nimoy had hoped when they executed the move during filming, explaining that it would be similar to "feeling an electrical charge." From then on, the pinch was referred to as the FSNP, for Famous Spock Nerve Pinch in Star Trek’s scripts.
Use within the franchise
Since Spock, various other characters in the Star Trek spin-offs have used the technique, however the fact that some of these have included non-Vulcan characters creates some confusion about the above explanation as to how the nerve pinch is achieved-- likely among writers and production-staff, since in the episode "The Omega Glory" Kirk tells Spock "Pity you can't teach me that" (i.e. the Vulcan Nerve Pinch), and Spock replies "I have tried, Captain." The first non-Vulcan was the android Data, followed by the Changeling Odo, Voyager’s holographic Doctor, and the humans Jean-Luc Picard, Seven of Nine, and Jonathan Archer (though Archer was carrying the katra of the ancient Vulcan Surak at the time). In prequel series Star Trek: Enterprise, T'Pol uses it in the 4th episode of the first season ("Strange New World") on Travis Mayweather to calm him down. Other examples of its use in that series include incapacitating Dr. Phlox before he can lobotomize Travis Mayweather in the 2nd season episode "Singularity", and again in the 3rd season episode "Carpenter Street", on the kidnapper Loomis to stop him escaping from his apartment.
Some humans, however, have been unable to use the nerve pinch. When Dr. McCoy was in possession of Spock’s katra he was unable to use the nerve pinch despite also being a doctor of great skill. This was partially due to McCoy's arthritis at the time.
The nerve pinch has been used on Vulcans and the vulcanoid Romulans several times, showing that neither race is immune to the technique. In the 2013 film Star Trek Into Darkness, Spock used the pinch on the film's villain, Khan, during their final battle. Though it appeared to cause him immense pain, it did not lead to unconsciousness, suggesting Khan and similar superhuman creations have limited tolerance to the grip. However, in the original episode "Space Seed" Spock does use the Vulcan Nerve Pinch on one of Khan's henchmen, with typical results of causing instant unconsciousness, despite all indications that he was similarly superhuman.
In the 1986 film Star Trek IV: The Voyage Home, while traveling in a San Francisco city bus, Spock used the Vulcan neck pinch to subdue a punk traveler who rudely ignored Kirk's request that he turn off his boom box as his music was causing the other travelers discomfort. This action garnered Spock applause from the relieved travelers on a bus.
The nerve pinch can also be used on non-humanoid creatures. In the Animated Series episode "Yesteryear", Spock uses the nerve pinch on a la matya during a time-travel adventure to save the life of his younger self. In the 1989 film Star Trek V: The Final Frontier, Spock uses the pinch to subdue a horse during a battle on the planet Nimbus III.
Use outside the series
The Vulcan nerve pinch has been referred to and parodied in many other television series:
- An episode of Mork and Mindy shows Mindy's father using the Vulcan Nerve Pinch on a hysterical Mork, saying "I saw this on a TV show once;" thus, it apparently works on Orkans.
- The protagonists of the TV series The Powers of Matthew Star employ a method of strictly defensive pressure-point manipulation referred to as "digital tranquilization".
- On a 1990 episode of A Different World, "Getaway (Part 2)", Walter uses the nerve pinch to subdue two dangerous drug dealers in the nick of time and a little later to silence a talkative Whitley.
- In an episode of Futurama, URL uses the Vulcan nerve pinch, followed by saying "Mama said Spock you out" (also a reference to the LL Cool J song, "Mama Said Knock You Out"). In another episode actor Leonard Nimoy attempts to use the move on Bender (unsuccessfully), first remarking "Let's see if this actually works."
- In an episode of Chuck, "Fear of Death", Agent Rye (Rob Riggle) uses something similar to knock out a guard, then jokes he learned it from Star Trek.
- During an episode of Kung Fu, a young Kwai Chang uses something resembling the neck pinch on a Chinese soldier.
- During an episode of Kung Fu: The Legend Continues, Kwai Chang Caine II uses the neck pinch to subdue a henchmen from behind by breaking his arms through a wooden door and applying the nerve pinch to the unsuspecting bad guy, thus subduing him.
- In a fourth-season episode of Soap, Jodie Dallas, played by Billy Crystal, is surprised when he successfully uses the "Vulcan neck pinch" and thanks Star Trek.
- In an episode of The Simpsons titled "Mayored to the Mob", it is frequently used (even comically overused) by then-bodyguard Homer Simpson (perhaps the only occasion when someone is seen performing the pinch on himself).
- In the Stephen King mini-eries The Langoliers (1995) when passenger Nick Hopewell confronts an irate businessman, Craig Toomey, on a red-eye flight from Los Angeles to Boston. When Mr. Toomey wakes up to the screams of a young blind girl and notices that all but ten people on the plane are no longer there, he demands answers from a deadheading pilot. Mr. Hopewell interjects and asks Mr. Toomey, "You ever watch Mr. Spock on Star Trek?" Mr. Toomey responds, "What the hell are you talking about?" Mr. Hopewell replies, "'Cause if you don't shut your cakehole, you bloody idiot, I'll be happy to demonstrate his Vulcan sleeper-hold for you."
- In an episode of My Name Is Earl titled "Early Release" (season 3, episode 12), Darnell incapacitates a prison guard using the nerve pinch. Joy realizes that Darnell had used the same technique on her several nights previous.
- In the iCarly episode "iPsycho", Sam Puckett uses the pinch against Nora Dirshlitt, a girl that held the crew hostage in her house. It is later called the "Vulcan Squeezy-thing" by Spencer at the end of the episode.
- In the BBC series Red Dwarf episode titled Legion, Kryten parodies the pinch and calls it the "Ionian Nerve Grip".
- In Jackie Chan Adventures, Uncle uses the pinch several times in the series. Even Shendu, one of the main villains used it twice, the first time was when he possessed Jades body because he used the sheep talisman to astral project himself, he used it on Captain Black and one of Black's men at the same time, and then he used it on Uncle in the Season 2 premier while inhabiting Valmont body, another villain in the show.
- In Phineas and Ferb, Ferb Fletcher uses the pinch on Bufford von Stomm at the end of the episode "Raging Bully".
- In Zoey 101, a girl named Quinn was able to use the nerve pinch and used it in several episodes. However, this technique was done to the arm instead of the neck.
- In Codename: Kids Next Door, Numbuh 3 tries to use that move; however, it fails miserably.
- In Episode 10 of Season 2 on The Librarians, Flynn is seen bringing the nerve pinch slowly from above on a person he's fighting, but it cuts away just as he makes contact. When the camera goes back to him, the man has fallen unconscious.
- In Ultraman Ginga, the Dark-Lived Ultraseven uses this move while restraining Ginga.
- In Mel Brooks' film Spaceballs, Lone Starr tries to use it on a henchman, initially unsuccessfully, but the henchman points out Lone Starr's mistakes - he gripped where the head meets the neck, when he should have gripped where the neck meets the shoulders - and is used again, successfully this time.
- In Hudson Hawk, the butler, Alfred, uses it on Hudson Hawk (Bruce Willis).
- In You Don't Mess with the Zohan, the Zohan uses the nerve pinch on a crying kid in a hair saloon, then suggests that it is a good time to shave his neck.

Use prior to the series
In the first series  Doctor Who episode "The Warriors of Death" from the story "The Aztecs", Ian Chesterton holds up his thumb and boasts "This is all I need [to defeat an enemy]," and proceeds to grip the Aztec warrior Ixta between the shoulder and neck, rendering him unconscious.
Over the years, fans and Star Trek Expanded Universe writers have made a number of suggestions as to how it would work.
The book The Making of Star Trek by Stephen E. Whitfield and Gene Roddenberry offers a simple explanation: the pinch blocks blood and nerve responses from reaching the brain, leading to unconsciousness. How this might lead to instantaneous unconsciousness is not explained. (Preventing all blood flow to the brain can result in unconsciousness, but many seconds later.) In this earliest of Star Trek reference books, the pinch is referred to as the “Spock Pinch.”
Another conjecture is that it can be done by applying strong and surgically precise pressure over baroreceptors of the carotid sinus at the base of the humanoid neck. The objective would be to elicit the baroreceptor reflex as the receptors detect an apparent high pressure state due to the externally applied force and causes reflex bradycardia and/or hypotension, leading to decreased blood supply to the brain and syncope.
A third conjecture is paranormal rather than medical: because of Vulcans’ telepathic nature and incredible control over their own bodies, they are able to send a burst of neural energy into another being and overload its nervous system, rendering it unconscious (although the pinch does not work on all species, nor on the time-travelling human Gary Seven). This was supported by the fact that Dr. McCoy could not use it in Star Trek III, but it has been rendered moot by the fact that many non-telepathic characters used it in later Trek series, such as the android Data.
The canonical mechanism of the nerve pinch was finally offered in the episode "Cathexis" of Star Trek: Voyager. There, the Doctor inspects a crewmember who was found unconscious and observes an extreme trauma to the trapezius neck bundle, "as though her nerve fibers have been ruptured"; and it is later revealed that the person was the victim of a nerve pinch.
The Star Trek episode “The Enterprise Incident” includes a scene in which Spock administers the so-called "Vulcan death grip" to Kirk to convince Romulan onlookers, apparently unfamiliar with Vulcan techniques, that Kirk had been killed. In fact, Spock had merely used a particularly powerful nerve pinch to put Kirk into a deep unconsciousness that closely resembled death. Kirk awoke a short time later with head and neck pain, but no lasting injury. The "death grip" differs from the "nerve pinch" in that the nerve pinch is administered to the neck area, and the death grip was administered to Kirk's face; the palm directly over the nose and the fingers spread out over the rest of the face. This also differs from the "Vulcan mind meld" grip which is administered to only one side of the face. The very existence of a Vulcan "death grip" is often quickly denied by fans via a popular phrase: "There's no such thing as a Vulcan death grip" (first used by Nurse Christine Chapel in "The Enterprise Incident").
