Touch of Death

The touch of death (or death-point striking) refers to any martial arts technique reputed to kill using seemingly less than lethal force targeted at specific areas of the body.
The concept known as "dim mak" (), alternatively "" () traces its history to traditional Chinese medicine acupuncture. Tales of its use are often found in the Wuxia genre of Chinese martial arts fiction. "Dim mak "is depicted as a secret body of knowledge with techniques that attack pressure points and meridians, said to incapacitate or sometimes cause immediate or even delayed death to an opponent. Little scientific or historical evidence exists for a martial arts "touch of death", although it has been confirmed that trauma may cause disproportionately catastrophic consequences when applied to known pressure points under specific circumstances. Commotio cordis, for example, is an often lethal disruption of heart rhythm that occurs as a result of a blow to the area directly over the heart (the precordial region), at a critical time during the cycle of a heart beat causing cardiac arrest.
The concept known as vibrating palm originates with the Chinese martial arts "Neijing" ("internal") energy techniques that deal with the "qi" energy and the type of force ("jin") used. It is depicted as "a technique that is part psychic and part vibratory, this energy is then focused into a wave".
Claims of practicability.
Numerous martial artists claim to practice the technique in reality, beginning in the 1960s, when the term was advertised alongside the English translation "The Death Touch" by American eccentric Count Dante.
In 1985, an article in "Black Belt" magazine speculated that the death of Bruce Lee in 1973 might have been caused by "a delayed reaction to a Dim-Mak strike he received several weeks prior to his collapse". Other authors have also said Lee's death may have been due to a "quivering palm technique" (alongside an article about Choy Li Fut instructor Wong Doc-Fai) to the effect that "dim mak does actually exist and is still taught to a few select kung fu practitioners." A 1986 book on "qi" identifies "dim mak" as "one of the secret specialities" of "wing chun". However, this matter is not identified in the "ving tsun kin kut" and traditional practitioners of "ving tsun" ("wing chun") take no stance in the matter.
During the late 1980s, Erle Montaigue (1949–2011) published a number of books and instruction videos on "dim mak" with Paladin Press. Montaigue claims to be "the first Westerner to be granted the degree of 'Master' in "taijiquan", awarded by Master Wang Xin-Wu in 1985. According to Montaigue's own account, "dim mak" is an aspect of traditional old Yang style "taji quan" which he claims he began learning in 1978 from a master called Chiang Yiu-chun who died in the month of May. Montaigue stated this man was an illegal immigrant, making his existence difficult to verify. Erle subsequently learned the remaining "qi"-disruptive" forms of "wudang shan" from Liang Shih-kan in 1995. Paladin Press has other titles on the topic of "dim mak", including Kelly (2001) and Walker and Bauer (2002), both with a foreword by Montaigue.
Around 1990, Taika Seiyu Oyata founded the style of Ryū-te which involves "pressure point fighting" (""). In the 1990s, karate instructor George Dillman developed a style that involves "kyūshojutsu", a term that he identifies with "dim mak". Dillman eventually went as far as claiming to have developed "qi"-based attacks that work without physical contact ("no-touch knockout" techniques), a claim that did not stand up to third-party investigation and was consequently denounced as fraudulent.
