Q

In George et all 2006 investigation :

a) Focused on the immediate hypoalgesic effects of lumbar SMT on thermal pain sensitivity in asymptomatic subjects.
b) Subjects then rated their delayed (“second”) pain after the first, third, and fifth heat pulses (believed to be Cfibre mediated)

Q

Wind-up is a phemomen:

a) Due to constant peripheral nociceptive c-fiber input
b) An example of central sensitization that occurs within dorsal horn cells
c) Can only be measured indirectly by temporal summation (C-fiber pain)
d) All of the above

Wind up results from tonic (constant) peripheral nociceptive c-fibre input and is an example of central sensitization that occurs within dorsal horn cells

direct measure of windup is not feasible in humans - temporal summation (second c-fibre pain) is indirect measure

Tonic activation of these dorsal cells induces a central hyperalgesia mediated at the spinal cord level, such that subsequent pain stimulus of standard amplitude are incorrectly relayed as increased in intensity
