Q

chronic primary pain

A

“Chronic primary pain is pain in 1 or more anatomic
regions that persists or recurs for longer than 3
months and is associated with significant emotional
distress or significant functional disability
(interference with activities of daily life and
participation in social roles) and that cannot be
better explained by another chronic pain condition.

Q

CRPS budapest criteria

A
  1. Continuing pain, which is disproportionate to any inciting event
  2. Must report at least one symptom in three of the four following categories:
  3. Sensory: reports of hyperesthesia and/or allodynia
  4. Vasomotor: reports of temperature asymmetry and/or skin color changes and/or skin color asymmetry
  5. Sudomotor/edema: reports of edema and/or sweating changes and/or sweating asymmetry
  6. Motor/trophic: reports of decreased range of motion and/or motor dysfunction (weakness, tremor, dystonia)
    and/or trophic changes (hair, nail, skin)
  7. Must display at least one sign at time of evaluation in two or more of the following categories:
  8. Sensory: evidence of hyperalgesia (to pinprick) and/or allodynia (to light touch and/or deep somatic pressure
    and/or joint movement)
  9. Vasomotor: evidence of temperature asymmetry and/or skin color changes and/or asymmetry
  10. Sudomotor/edema: evidence of edema and/or sweating changes and/or sweating asymmetry
  11. Motor/trophic: evidence of decreased range of motion and/or motor dysfunction (weakness, tremor, dystonia)
    and/or trophic changes (hair, nail, skin)
  12. There is no other diagnosis that better explains the signs and symptoms

distress (anxiety, anger/frustration or
depressed mood) or functional disability
(interference in daily life activities and
reduced participation in social roles)”

Q

FM treatment

A
  • Treatment should be individualized
    *Consider Associated Conditions
    *Mental Health Problems
    *Chronic Overlapping Pain Conditions

Q

FM guidelines

A

The European League Against Rheumatism
* Tailored approach directed at key symptoms (pain, sleep
disorders, fatigue, depression, disability)

German
* Management tailored to severity
* Mild disease not requiring any specific treatment
* Severe disease multicomponent therapy (drug
treatment, aerobic exercise, psychological treatments)

Q

post exertional malaise (PEM)

A

Worsening of symptoms following minor physical or mental
exertion that would have been tolerated previously.
* Symptoms typically worsen 12 to 48 hours after activity
* can last for days or weeks
* First described in ME/CFS
* Linked to Long COVID & FM

17
Q

PEM and pacing

A

Patients determine individual limits for mental and
physical activity.
* Use of activity and symptom diaries may help patients
identify their “energy envelope.”

  • “Healthcare providers need to be aware that their
    patients’ ability to function may seriously deteriorate if
    they exceed their individual capacities. In general, patients
    should not push themselves beyond their capacities as
    this may exacerbate their symptoms and trigger PEM.”
18
Q

myofascial pain syndrom (MPS)

A

Characterized by trigger points (TrP)
* Active TrP is any point that causes tenderness
and referred pain on palpation. Palpation may
also cause autonomic symptoms such as skin
redness, sweating, and dizziness.
* Latent TrP does not evoke pain spontaneously,
and local or referred pain occurs only with
strong digital pressure. They may change
muscle activation patterns or cause muscle
weakness in pain
-free patients.
* Reproduction of painful symptoms is the
diagnostic criterion differentiating between the
two

Definition varies
* Reported lifetime incidence of 85%
* 77.7% of asymptomatic individuals have
Latent TrP in LEs
* Intervention directed at trigger points

19
Q

sleep hygiene

A

Go to bed and get up at the same
time every day
* Keep your bedroom quiet, relaxing,
and at a cool temperature
* Turn off electronic devices 30
minutes before bedtime
* Avoid large meals and alcohol
before bedtime
* Avoid caffeine in the afternoon or
evening
* Exercise regularly and maintain a
healthy diet

20
Q

a sleep diary

A
  • A sleep diary should include when you:
  • Go to bed
  • Wake up during the night
  • Wake up in the morning
  • Take naps
  • Exercise
  • Drink alcohol or caffeinated drinks
  • Take medications
21
Q

how to refer someone to a mental health provider

A

make it about the patienns goals
- “Seems like the headaches you are getting are really
hassling you at work, and it seems like they get worse
with stress. Therapy can help with that and it might
make you less miserable at work and home.”

make it optional
* “It’s not a requirement, just a thought.”
* “It’s really up to you,”

make it conditional
- only commiting to one visit
- being clear length of tx and level of commitment is up to them

don’t make promises

22
Q

how to practice graded motor imagery 3 sequential parts

A

Practice in each stage lasts from 1
visit up to about two weeks

  • Progress to next stage when affected
    limb is performing near equal to
    unaffected without elevated pain sensations

the therapist working with the patient is more like a coach or supervisor

  • Patients practice hourly (frequency
    of practice is critical)
  • Return to graded activity should be
    included when symptoms are
    controlled
23
Q

mirror movements

A
  • Sit comfortably
  • Jewelry and clothing off both limbs
  • Affected limb in the box and forget about it
  • Move unaffected hand in various ways while
    looking in the mirror
  • Progress to replicating movements of the
    unaffected hand with affected hand (while still
    in mirror)
  • Vary speed, size, intensity of movements with
    unaffected hand, replicate with affected hand
  • Accuracy important, illusion must be complete,
    movement of the unaffected limb must be
    accurate
24
Q

graded motor imagery

A

left/right discrimination
explicit motor imagery
mirror therapy

25
Q

graded motor imagery

A

a treatment for CRPS
- strong evidence of effficacy
- no known risks
- minimal side effects

it is a sequential process of laterality recontruction, motor imagery and mirror therapy (think graded exercise)

it gives people who have pain when just thinking about moving something positive to work on

26
Q

3 sequential parts to graded motor imagery

A

laterality training
- recognizing pictured hands or feet as being left or right

imagery
- imagined movements or postures of affected limb

mirror box therapy
- mirror movements
