Q

(true/false) CRPS is normally caused by a noxious event and is hard to control.

A

false (not caused by a noxious event)

17
Q

What are the s/s of type I CRPS?

A
  • pain
  • redness
  • allodynia
18
Q

definition: touching an area and causing pain strictly through mechanoreceptors

A

allodynia

19
Q

Fibromyalgia affects (males/females) more.

A

females

20
Q

What is the s/s of fibromyalgia?

A

TTP pain

21
Q

What are the mechanisms that cause chronic pain?

A
  • wind up
  • damage to PNS
  • reorganization of the CNS
22
Q

definition: As damage to a nerve tries to regenerate, the axons converge due to not enough myelin separating them (therefore, doubling the effect)

A

ephaptic transmission

23
Q

definition: a mild stimulus causes an increase in neurotransmitters within the spinal cord due to sensitization of the pathway

A

wind up

24
Q

In allodynia, the _____ will activate the painful pathway.

A

mechanoreceptor

25
Q

definition: having trouble distinguishing L from R

A

Laterality
