  2. Threshold of pain - Wikipedia

    en.wikipedia.org/wiki/Threshold_of_pain

    So, if a hotplate on a person's skin begins to hurt at 42 °C (107 °F), that is the pain threshold temperature for that bit of skin at that time. It is not the pain threshold (which is internal/subjective) but the temperature at which the pain threshold was crossed (which is external/objective).

  3. Pain tolerance - Wikipedia

    en.wikipedia.org/wiki/Pain_tolerance

    Pain tolerance is the maximum level of pain that a person is able to tolerate. Pain tolerance is distinct from pain threshold (the point at which pain begins to be felt). [1] The perception of pain that goes in to pain tolerance has two major components. First is the biological component—the headache or skin prickling that activates pain ...

  4. Nociceptor - Wikipedia

    en.wikipedia.org/wiki/Nociceptor

    [15] [4] Peripheral sensitization represents a form of functional plasticity of the nociceptor. The nociceptor can change from being simply a noxious stimulus detector to a detector of non-noxious stimuli. The result is that low intensity stimuli from regular activity, initiates a painful sensation. This is commonly known as hyperalgesia ...

  5. Pain - Wikipedia

    en.wikipedia.org/wiki/Pain

    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.

  6. Hyperalgesia - Wikipedia

    en.wikipedia.org/wiki/Hyperalgesia

    Hyperalgesia (/ ˌ h aɪ p ər æ l ˈ dʒ iː z i ə / or /-s i ə /; hyper from Greek ὑπέρ (huper) 'over' + -algesia from Greek ἄλγος (algos) 'pain') is an abnormally increased sensitivity to pain, which may be caused by damage to nociceptors or peripheral nerves and can cause hypersensitivity to stimulus.

  7. Dolorimeter - Wikipedia

    en.wikipedia.org/wiki/Dolorimeter

    A dolorimeter is an instrument used to measure pain threshold and pain tolerance. Dolorimetry has been defined as "the measurement of pain sensitivity or pain intensity". [ 1 ] Dolorimeters apply steady pressure, heat, or electrical stimulation to some area, or move a joint or other body part and determine what level of heat or pressure or ...

  8. Pain scale - Wikipedia

    en.wikipedia.org/wiki/Pain_scale

    The sensation of pain is an unpleasant or discomforting feeling that can manifest as sensations such as pricking, tingling, burning, stinging, shooting, aching, or electric. Pain can vary in intensity, from very mild to very severe; duration, short-lived to chronic; and location, one localized area or all over the body. [4]

  9. Pain stimulus - Wikipedia

    en.wikipedia.org/wiki/Pain_stimulus

    Pain stimulus is a technique used by medical personnel for assessing the consciousness level of a person who is not responding to normal interaction, voice commands or gentle physical stimuli (such as shaking of the shoulders). [1]
