In 1968, three years after the introduction of the gate control theory, Ronald Melzack concluded that pain is a multidimensional complex with numerous sensory, affective, cognitive, and evaluative components. Melzack's description has been adapted by the International Association for the Study of Pain in a contemporary definition of pain. [1]
Melzack's recent research at McGill indicates that there are two types of pain, transmitted by two separate sets of pain-signaling pathways in the central nervous system. Sudden, short-term pain, such as the pain of cutting a finger, is transmitted by a group of pathways that Melzack calls the "lateral" system, because they pass through the ...
Wall & Melzack's Textbook of Pain is a medical textbook published by Elsevier. It is named after Patrick David Wall and Ronald Melzack, who introduced the gate control theory into pain research in the 1960s. First released in 1984, the book has been described as "the most comprehensive scientific reference text in the field of pain medicine". [1]
The McGill Pain Questionnaire, also known as McGill Pain Index, is a scale of rating pain developed at McGill University by Melzack and Torgerson in 1971. [1] It is a self-report questionnaire that allows individuals to give their doctor a good description of the quality and intensity of pain that they are experiencing.
While at McGill, he and Ronald Melzack devised the now widely accepted model of the three dimensions of pain. [ 3 ] [ 4 ] He was the first to record the responses of single neurons to noxious stimuli in an awake animal [ 5 ] and, with colleagues, to use functional brain imaging to show responses in the human brain specifically to heat pain as ...
But after Henry Head in England published a series of clinical observations between 1893 and 1896, and von Frey's experiments between 1894 and 1897, the psychologists migrated to specificity almost en masse, and by century's end, most textbooks on physiology and psychology were presenting pain specificity as fact, with Titchener in 1898 now ...
The neuromatrix theory, initially coined by psychologist Ronald Melzack in the 1990s, proposes that there is an extensive network connecting the thalamus and the cortex, and the cortex and the limbic system. [8]
Psychoanalytic model: In the context of rehabilitation psychology, Freud's concept of castration anxiety can be applied to severe losses, such as the loss of a limb. This concept is reflected in Jerome Siller's stage theory of adjustment, designed to increase understanding of acceptance and adjustment following sudden disability.
