Gateway Control Theory
Gateway Control Theory
Date of last revision July 26, 2011
* Door control theory was defined by Melzack and Wall in 1965. 2. This theory explains in regards to a pain-modulating system in which a neural gate present in the spinal cord can make thereby modulating the understanding of soreness. * The gate control theory advised that emotional factors be involved in the understanding of soreness. Terms
* Pain - an unpleasant sensory and mental experience associated with actual or perhaps potential damaged tissues. * Analgesia - the selective suppression of pain without effects in consciousness or perhaps other sensations. * Nociceptors - sensory receptor whose activation causes discomfort * Pain threshold: the point where a stimulus is perceived as painful. 5. Phantom limb pain – thoughts of discomfort in a limb that is no longer there and has no performing nerves. 5. Sensation – the receiving, converting, and transmitting information in the external and internal globe to the human brain. Major Concepts www.currentnursing.com
* Three systems found in the spine act to influence notion of discomfort, viz; * the substantia gelatinosa in the dorsal horn,
* the dorsal line fibers, and
* the central transmission cells.
* The noxious impulses are influenced by a " gating device. ” 2. Stimulation with the large-diameter fabric inhibits the transmission of pain, hence " final the gateway. ” While, when smaller fibers happen to be stimulated, the gate is definitely opened. * When the gateway is shut down signals by small size pain fibers do not inspire the hinten horn transmission neurons. 2. When the gate is open pain alerts excite hinten horn indication cells. * The gating mechanism is usually influenced by simply nerve urges that come down from the brain. * Elements which influence opening and closing the gate happen to be: * The amount of activity in the pain fibers.
* The quantity of activity in other...
