From: Pain sensitivity at rest and during muscle contraction in persons with rheumatoid arthritis: a substudy within the Physical Activity in Rheumatoid Arthritis 2010 study

  RA
(n = 45)
HC
(n = 20)
p Value
Global pain at rest (VAS), 0–100, median (25th–75th percentiles) 11 (0–24) 0 (0–0) <0.001
PPTs (kPa)    
 Individual PPT mean, kPa, mean (SD) 318 (146) 487 (194) <0.001
 Suprathreshold 4/10, kPa, mean (SD) 433 (202) 638 (215) 0.001

  1. Abbreviations: RA Rheumatoid arthritis, HC Healthy control subjects, PPT Pressure pain threshold, VAS Visual analogue scale
  2. Data are presented for global pain at rest, PPTs at rest (individual PPT mean) and suprathreshold pressure pain (suprathresholds 4/10 and 7/10) for participants with RA and HC
