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 ...

The neurobiological underpinnings of gender differences in pain perception, and how these differences may be modified by age, are incompletely understood, placing patients at risk of suboptimal pain management.
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.
20 Οκτ 2020 · Pain threshold is defined as the minimum intensity of a stimulus that is perceived to be painful. Previously, this threshold was believed to be uniform across individuals, such that given intensity of a stimulus was thought to produce a given pain response.
The pain threshold refers to the amount of stimulus intensity required to evoke a painful sensation. It marks the transition from the absence of pain sensation to the presence of pain sensation. In the laboratory, it is determined through psychophysical procedures that control for biases and uncertainties in assessing painfulness.
1 Σεπ 2011 · In this article, mouse models of acute mechanical and thermal pain and inflammatory, visceral, and neuropathic pain are discussed. These behavioral measures can be used to phenotype transgenic mice for target validation and mechanistic studies, as well as to screen potential analgesic compounds.
1 Σεπ 2011 · Pain afflicts a fifth of the population, and animal models have proven useful in target validation and analgesic drug development. Thresholds to pain are tested by applying a sensory stimulus, such as heat or pressure, and observing the resulting withdrawal behavior.
