What are the stages of CBT?
Wall & Melzack: 1. Assessment stage 2. Cognitive stage 3. Behavioural stage 4. Learning stage Alternatively: 1. Assessment 2. collaborative reconceptualization of patient’s view of pain 3. acquisition of skills 4. consolidation of skills, including cognitive and behavioral rehearsal 5. generalization, maintenance, and relapse prevention 6. booster sessions and follow-up
Compare and contrast CBT and mindfulness based therapy
CBT
- targets cognition distortions
- attempt to reframe or change automatic thoughts;
- uses behavioral activation;
- directive;
- structured;
- homework involved
-
MBSR
- acknowledge the thought or emotion but does not attempt to change the thought or emotion;
- focuses on the present;
- does not address underlying core beliefs;
- empowering and accepting;
- teaches to notice and accept problem events
- changes relationship to the thoughts, sees them as passing events
Compare and contrast MBSR and MBCT
MBSR:
- focused on noticing and acceptance
MBCT:
- Paying attention in a particular way on purpose, in the present moment, non-judementally
- focused awareness, attention regulation
- open monitoring (emotional regulation, emotional non-reactivity, non-judgemental, acceptance)
Indications for hypnosis?
- Headache
- labour pain
- procedure induced pain
- cancer (bone marrow transplant, lumbar punctures)
- pain from chemotherapy and radiation
- arthritis
- sickle-cell
- dental,
- post-surgical pain
- burns (debridement, dressing change)
What is the mechanism of action of hypnosis?
- decrease pain-related affect (limbic ACC)
- decrease pain sensation (SS1; prevent awareness)
- inhibit spinal-level processing (DHC)
Stages of hypnosis?
- deep relaxation
- absorbed/ focused
- no judging, monitoring, censoring
- time distortion
- automaticity (action before thought)
What are examples of psychological self-regulation techniques for pain management?
- Relaxation therapy
- Biofeedback
- Guided imagery
- Autogenic therapy
- Verbal induction
- Mindfulness techniques
What brain area is associated these functions?
- amygdala
- PFC
- DLPFC (dorsolateral prefrontal cortex)
- ACC
- insula
- somatosensory cortex
- thalamus
- PAG/RVM
- amygdala - emotional component of pain experience
- PFC - inhibitory control of amydala
- DLPFC (dorsolateral prefrontal cortex) - executive function and ability to inhibit
- ACC - emotional and motivational component
- insula - emotional component
- somatosensory cortex - location and intensity of painful stimulus
- thalamus - location and intensity of painful stimulus
- PAG/RVM - descending feedback system
What are 4 skills used to enhance self-efficacy in Stanford pain self-management program?
- skills mastery
- modelling
- reinterpretation of physiological symptoms
- persuasion
What are the five stages of readiness to change?
Pre-contemplative Contemplative Preparation Action Maintenance
Motivational interviewing skills?
OARS
- open ended questions
- affirmations
- reframing
- summarizing
What are the 5 principles of Motivational interviewing?
DEARS
- develop discrepancy
- emotional empathy
- avoid arguments
- rolling with resistance
- supporting self-efficacy
Name six factors that underlie the placebo response?
- biases
- regression to the mean
- spontaneous remission
- detection ambiguity
- unidentified co-interventions
- psychosocial/psychobiological factors
When to refer to a psychiatrist?
- Major personality disorder
- PTSD
- Active substance use disorder
- High level of distress
- psychosis
- high scores on depression or anxiety screening scales
- any suicidal ideation
What are examples of yellow flags for back pain (when to refer to multidisciplinary team due to psycho-behavioral issues) ?
- catastrophization
- depression
- anxiety
- poor coping
- fear avoidance
- kinesophobia
- oversolicitous spouse
- maladaptive behaviors
- maladaptive cognitions or beliefs
- low self-efficacy
- high external locus of control
- secondary gain (litigation, compensation)
What are blue flags (perception of occupational)?
- not working
- poor work satisfaction
- fear of re-injury
- work related stress
Black flags (actual work conditions)?
- poor work conditions
- manual work
- unsociable hours
What are the mechanisms behind placebo response?
Psychological:
- conditioning (conscious or unconscious)
- expectancy (information, cognitive)
- desire/motivation
Biological:
- Endogenous opioid system (endorphin, enkaphalins, dynorphins)
- dopamine
- cortical networks
Mechanism – Brain :
- During anticipation: increase DLPFC (cognitive control)
PAG, orbitofrontal (evaluative/reward processing), rACC
- During treatment: decrease in ACC, Thalamus, insular cortex (*pain matrix)
Mechanism - Opioid vs. Non-opioid system:
- Naloxone sensitive: expectation, endogenous
opioid system, can be regional (somatotopic)
- Naloxone in-sensitive: conditioning (classical), growth
hormone, 5-HT, CCK (associated with negative verbal
suggestion or expectancy)
What is the neurological mechanism underlying mirror image pain ie. Allochiria?
-Ipsi injury induced, CL peripheral neurite loss
