Ratings of global pain intensity at rest, individual pressure pain threshold, and suprathreshold pressure pain (4/10 and 7/10) before intervention and at 1-year and 2-year follow-ups

n = 30	Before	One-year follow-up	Two-year follow-up	P values
Global pain at rest on a scale of 0 to 100, median (25th–75th percentiles)	11 (0–24)	8 (3–25)	6 (0–20)	0.040
PPT mean in kPa, mean (SD)	338 (136)	304 (140)	325 (141)	n.s.
Suprathreshold 4/10 in kPa, mean (SD)	458 (199)	412 (166)	426 (163)	n.s.
Suprathreshold 7/10 in kPa, mean (SD)	647 (302)	539 (230)	560 (193)	0.006
