No results posted yet for this study

Summary

Fibromyalgia (FM) is a chronic musculoskeletal pain disorder with unknown causes. Our previous studies showed abnormal sensations of second pain (wind-up), indicating central hypersensitivity as an important mechanism of FM. Triggering events have been implicated as the cause of central hypersensitivity.

Conditions

  • Fibromyalgia

Interventions

BEHAVIORAL

Paced Auditory Serial Addition task (PASAT)

Single and double digits are presented at intervals between 2 and 3 seconds and the participant must add each new digit to the one immediately prior to it. The participants will be asked to indicate by electronic button press whether the sum of the addition is 13 or not. The duration of the PASAT will be two 12-min tasks.
