lecture 10: pain experience and response recording Flashcards
pain definition
an unpleasant sensory and emotional experience associated with actual or potential tissue damage
pain experience
- traditional biomedical: severity is proportional to tissue damage and thee is an organic explanation
- biopsychosocial: psychologicla and social factors included in diagnosis, severity, and treatment
pain pathway
- sensation: activation of organ –> neural impulses to brain
- perception: brain’s organisation and interpretation of sensory input
describing pain
socrates:
- site
- onset: what were you doing when it start(-s/-ed)
- character: type ie dull, twisitng, sharp, tense
- radiation: does it move
- associated symptoms: ie nausea vomitting
- timing: is it constanct, or does it come and go
- exacerbating symptoms: what makes it better or worse
- severity: how bad?
why feel pain?
- prevents tissue damage (protect or prevent further)
- promotes immobilisation so you can heal
pain-related behaviour
- outward exression
- attempt to reduce
- attempt to cope or ignore
- behaviours can impact the way we perceive and experience pain
three theories of chronic pain
- gate control theory
- operant conditioning theory
- cognitive behavioural theory
gate control theory (pain)
a gate exits at spinal chord that can block some pain signals. two way input
- ascending: biological in nature (receptors) and modulated by non pain stimuli like touch and pressure
- descending: psychological that is modulated by attention, emotional
operant control theory (pain)
pain behaviours create a cycle of chronic pain where patient receives rest and/or attention which can then increase the expression of pain in the future. Or you do something, it causes pain, you don’t do it again or ask for help, further reduction in the activities doesn’t address root of pain, it might get worse
cognitive behaviour theory (pain)
cognitive triangle, (thoughts, behaviour, feelings, all influencing each other). role of a patients appraisals (experience, perception) and coping strategies (responses) is important
treatment of chronic pain for gate control
focus on treatments that can close the gate (not necessarily cutting of the connection to the brain)
- rubbing
- distraction
- relaxation exercises
- non- traditional therapy like massage,, acupuncture
treatment of chronic pain for operant control
-decrease unhelpful behaviours like avoidance
- increase helpful behaviours like exercise/relaxation
treatment of chronic pain for cognitive behavioural
transition patients from passive coping towards active coping (shift from avoidance, ignoring, increase clinician visits to regular exercise, distraction, relaxation)
- develop skills to change negative thoughts and behaviours
chronic primary pain
pain that
- persists or recurs for longer than 3 months
- is associated with significant emotional distress and/or functional disability
- includes symptoms not better accounted for by another diagnosis
