6. why was moseley 2006 the most reliable
- the others did not have a control
- the others had 13 and and 18 participants
- the others werent double blinded
- the others suffered from self reporting bias
7. Why isn't allodynia useful?
- Pain helps scar tissue from breaking
- Up regulation of receptors
- It looks pretty
- It circulates more blood to area due to itching
8. If it is CRPS type 2, why would you try neurodynamics?
- Sliders and tensioners to encourage movement of inflammation and encourage nutrient flow
- Repetitive stretch and strain can cause mechanical irritation
- If a nerve is painful, pain can be perceived anywhere in the nerve
- Nerve impulse releases neuropeptides such as substance P at the end of the nerve
9. What is the underlying mechanism for CRPS?
- Immunological mechanisms
- Alterations to central nervous system causing central sensitisation
- All of them
- Peripheral sensitisation caused by peripheral inflammation
10. In peripheral sensitisation, substance P changes A beta fibres in to what?
- nociceptors
- DPAG
- rostral ventral medulla
11. How much practice was required for mirror therapy
- 2 hours a day for 4 days a week for 5 weeks
- 3 hours a day for 6 days a week for 5 weeks
- 2 hours a day for 5 days a week for 4 weeks
- 1 hours a day for 4 days a week for 3 weeks
12. Desensitisation is a new treatment. What are the problems with the current study?
- Low participant numbers
- Retrospective cohort study with no control
- Lack of double blinding
- Observational study
13. How many participants were included in Moseley 2006
- 50 overall, 40 with CRPS
- 40 overall, 36 with CRPS
- 50 overall, 36 with CRPS
- 36 overall, 20 with CRPS
14. Which of these is not one of the strategies recommended by the RCP guidelines
- Psychological therapy
- Medication
- Physiotherapy
- Occupational therapy
- Education
15. What can cause central sensitisation?
- Maladaptive psychosocial factors causing less blocking from PAG and RVM
- All of these
- Descending inhibition turning down
- Neuroplasticity enlarging the homunculus and increasing cortical representation of pain areas
16. What were elements of bias in moseley 2006
- single blinded, no control group
- retrospective study, no control group
- single blinded, self reporting, low participant numbers
- single blinded, low participant numbers
17. what were the percentages for CRPS
- 65% trauma, 37% radius#
- 65% trauma, 50% radius#
- 84% trauma, 65% radius#
- 37% trauma, 12% radius#
18. Which of these would be long term management for CRPS
- All of these
- Annual review by pain clinic
- Easy access to hydrotherapy
- Fast GP access
- Peer support groups
19. What are the positives of education?
- Education on lack of damage and not falling into boom/bust pattern
- Social learning theory effective but may not work for patients with psychological problems such as depression
- Need 20-30 minutes of activity for endorphin release, unlikely if the patient is in a lot of pain
- If educated wrong, may enforce negative beliefs
