Q

What are 6 Important clinical elements?

A
  1. thorough examinations

  3. exercise programs
  4. graded exposure- Gradual and slowly build up tasks
  5. goal setting
  6. self-efficacy
    • Building confidence (graded exposure is hepful) Reassurance and praise when tasks done well or if improvement is seen

Q

Why do we traditionally use biomechanics to explain persistent back pain?

A
  • Many health professionals profit from ongoing treatments and invasive approaches, products and surgery
  • Patient education regarding pain involves a paradigm shift
  • Physio taught that way
  • Physio can profit (eg. can give ongoing treatment = no use)

pain

A

fear-avoidance; pain catastrophization

34
Q

What is the aim of interview in persistent pain? What are 5 questions?

A

The aim is to develop a deep understanding of the person’s experiences, as well as discover what may motivate the patient

  1. What do you think is going on with your back?
  2. What do you think should be done for your back?
  3. Why do you think it has not improved?

inflated, fear-inducing

36

A

relationship

37
Q

What are 7 beliefs that can identify beliefs, barriers and change opportunities?

A
  1. Previous findings on investigations
  2. Previous explanations from health professionals
    • Difficulty coping with societal requirements
    • Lack of physical activity
    • Fear avoidance
    • Reliance or expectation around success of passive approaches
    • The need for protective movement habits.
      • Why? Are you afraid it will make it worse or does it actually hurt?
38
Q

Pain education may need to start with ‘de-education’. What does that mean?

A

correcting misinterpretations or unhelpful beliefs

39
Q

“De-education” may include sharing ______, helping understand that “findings” on tests and imaging may not correlate to pain.

A

normative data

Eg. have graphs that show normative data = show that it is normal (what you are getting)

40
Q

We can reiterate “bulging” discs appear on MRIs of people ____ (with/with no) LBP various studies have shown that “bulging” discs reabsorb over time and typically resolve in a few months.

A

with no

41
Q

Pain ____ (does/does not) equal pain.

A

does not

42
Q

Based on research/ evidence based practice, the only thing and most effective management is _____ for persistent back pain

A

exercise

43
Q

What are 5 key messages when reducing the cognitive threat of input?

A
  1. Simple messages should be used
  2. Based on what the patient already understands or is wanting to know
  3. Address patient’s concerns
  4. Address unhelpful beliefs
  5. Can you give messages that are based on what the patient already recognises?
    • Stress or worrying = more pain
    • Bracing or not moving = more pain
    • Exercise/active coping = better function and less pain.
44
Q

Eg. if they know that when they are stressed, they have more pain. What does that mean?

A
  • Emphasise this and use research to teach the patient
  • Show that it is not helpful = need to change
45
Q

What are 7 key messages for new beliefs and behaviours?

A
  1. The spine is strong, resilient and adaptable
    • One of the strongest structures f the body
  2. All tissues in the spine are adaptable
    • We can load it in different ways and it can adapt to that
  3. Pain is poorly related to tissue damage
  4. Protection can persist when there is no longer the need to protect
  5. Pain that persists is more about sensitivity to it rather than the damage
    • Alarm system keeps going even after the cause has gone away
  6. Many factors influence sensitivity both positively and negatively.
  7. Recognising these and managing them is a key to recovery
46
Q

The patient should be made aware of the sheer vastness and complexity of the nervous system: “There are more than 400 individual nerves that combined make more than 45 miles of nerves within your body, and they all are connected like a network of roads” This assists the patient in understanding that pain is complex, and therefore managing pain isn’t a one-step fix.

A

If they understand NS, more likely to understand their pain

47
Q

What are the metaphors/analogies for persistent pain?

A
  • The research currently shows pain education works best by using metaphors, examples, and pictures
  • Pain metaphors are used to convey the message that pain may not necessarily be a true reflection of the health of their tissues and persistent pain is usually not
48
Q

What are 5 things that Metaphors and analogies are often used to explain?

A
  1. How to understand pain
  2. Why pain persists
  3. Why tests show nothing ‘wrong’
  4. Self-management strategies
  5. What “feels” dangerous might not actually “be” dangerous
49
Q

This may help patients ____ their pain experience and aim to avoid patients falling into the mindset of “you think my pain is in my head.”

A

reconceptualize

50
Q

What is a good metaphor for persistent pain?

A

Sun burn metaphor - low tissue damage but high pain levels

  • Pain is not a true reflection of damage
51
Q

What is a good metaphor for persistent pain in terms of sensitivity?

A

An example is whereby the body’s nervous system is metaphorically described as an alarm system In one in four people, the alarm system does not calm down after ramping up, but remains extra sensitive

52
Q

What to know when damage has been causes (eg. step on nail)? • Force us to do something about it (avoid infection, gangerene) 1/4 get persistent pain • Hyper-sensitivity = less tolerance (eg. allodynia) • Changes in life • Why does it not come down? ○ Fear ○ Worries ○ Stress • How to turn it down? ○ Biological –> exercise, sleep, relaxation, meditation, diet…etc Can be helpful to draw a graph = tolerance can go down (NS changing)

A

A

53
Q

What is the alarm system metaphor?

A

Before the onset of this pain, the alarm system had lots of tolerance for activities, but since being extra sensitive, there is less tolerance Now, after a safe task or movement, the alarm system goes off. This metaphor of nerve sensitization gives the patient a different paradigm about why they still hurt

54
Q

What are 4 issues that that contribute to the alarm system remaining sensitive?

A
  1. failed treatments
  2. sleep, diet
  3. work stress and anxiety
  4. different explanations from health professionals
