Part 1 Flashcards
Gate pain theory
model for TENS
Who developed it?
Melzack & Wall’s Theory (1969’s) and revised in 1983
Noxious stimuli
modified both by activity within the spinal cord and by descending influences from the brain
feed-forward and feedback loops between
between the CNS & PNS.
Substantia gelatinosa in the spinal cord
acts as a “gate” to control access to the pain pathways.
ACUTE PAIN
Lasting less than 6 months Most often associated with new inflammatory conditions Unpleasant sensory perceptual, emotional, and mental experience provoked by acute disease or injury with autonomic, psychological, & behavioral responses.
RONIC PAIN
Lasting longer than 6 months Persistent pain that lasts beyond the expected time frame for tissue healing For fast healing tissues
PHANTOM PAIN
Pain originating from the damaged or amputated body part
REFERRED PAIN
Pain felt at a site other than origin Example: pain from the pancreas or stomach which is felt in the back
ORGANIC PAIN
Refers to any pain resulting from a disorder, abnormality or chemical imbalance in an organ system, Has a traceable and identifiable distribution specific to an organic system.
NON-ORGANIC PAIN –
Has no identifiable physical cause, meaning that it usually stems from psychological factors.
VISUAL ANALOGUE SCALE -VAS ADVANTAGES
Easily administered Requires little to no training or equipment
DISADVANTAGES
Due the subjectivity of rating pain, one patient may sense pain as more severe than another therefore not a highly reliable, objective tool for measurement.
Body Diagram ADVANTAGES
Good reliability Can be scored as organic – in accordance with anatomical patterns of pain Can be scored as non-organic – not in accordance with anatomical pain patterns
Body Diagram DISADVANTAGES
More time consuming to fill out Requires patient instruction More difficult to objectively analyze
