In 1894 Goldscheider extended the intensive theory, proposing that each tactile nerve fiber can evoke three distinct qualities of sensation – tickle, touch and pain – the quality depending on the intensity of stimulation; and extended Naunyn's summation idea, proposing that, over time, activity from peripheral fibers may accumulate in the ...
Most pain resolves once the noxious stimulus is removed and the body has healed, but it may persist despite removal of the stimulus and apparent healing of the body. Sometimes pain arises in the absence of any detectable stimulus, damage or disease. [3] Pain is the most common reason for physician consultation in most developed countries.
The threshold of pain or pain threshold is the point along a curve of increasing perception of a stimulus at which pain begins to be felt. It is an entirely subjective phenomenon. It is an entirely subjective phenomenon.
Combining early concepts derived from the specificity theory and the peripheral pattern theory, the gate control theory is considered to be one of the most influential theories of pain. This theory provided a neural basis which reconciled the specificity and pattern theories -- and ultimately revolutionized pain research.
Another type of pain, known as neuropathic pain, is caused by a direct problem or disease that affects the nerves in the central nervous system. [11] The sensory pathways the WDR neurons can play a role in. A subset of this neuropathic pain, known as chronic neuropathic pain, is characterized by its long lasting and high pain intensity.
At Melzack's urging they wrote a paper on the Gate control theory of pain and published it in Brain in 1962; according to Wall it was read by around three people. After expanding and rewriting the article they republished it as Pain Mechanisms: a new theory in Science in 1965 where it drew wider attention, with mostly negative comments. [11]
The opponent-process theory is a model that views two components as being pairs that are opposite to each other, such that if one component is experienced, the other component will be repressed. Therefore, an increase in pain should bring about a decrease in pleasure, and a decrease in pain should bring about an increase in pleasure or pain relief.
Pain management is an aspect of medicine and health care involving relief of pain (pain relief, analgesia, pain control) in various dimensions, from acute and simple to chronic and challenging.
