The temperature that is called painful 50 percent of the time would be the pain detection or sensory threshold. In contrast to this relatively reproducible pain-detection threshold, tolerance for pain differs widely among individuals.
Definition. Pain threshold is defined as the lowest stimulus intensity that reliably elicits the perception of pain. Attention as well as motivational and emotional factors are known to influence the pain threshold that can be measured in the laboratory.
Pain threshold, as other pain measures, can be influenced by a variety of biological, psychological, and situational factors, including the subject’s pain experience history and the instructions given by the experimenter.
Pain threshold is that point at which pain is just perceived; in more psychophysical terms, the 50% mark at which half the time there is pain and half the time there is no pain. Pain tolerance is an upper threshold, the point at which the patient no longer tolerates the presented stimulus and terminates stimulation by either withdrawing from it ...
24 Ιουλ 2023 · Pain is likely the most common symptomatic complaint in medicine; an understanding of its pathophysiology is critical to interpreting it in patients. Differentiating between the terms nociception and pain is worthwhile.
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.
Pain threshold is the point at which pain is first detected and tolerance is the point at which pain can no longer be endured, with both measures typically quantified as stimulus intensity (e.g. temperature) or exposure time.
