  • Significant data are in bold face.

  • * Based on a 0–10 scale with 10 being worse pain.

  • ** Based on 0–9.75 scale with 9.75 being greater intensity of symptoms consistent with fibromyalgia.

  • Units are kg/cm2. BPI-sf: Brief Pain Inventory short form; SIS: Symptom Intensity Scale; PPT: pressure pain threshold; CPM: conditioned pain modulation.
