From: Long-term, health-enhancing physical activity is associated with reduction of pain but not pain sensitivity or improved exercise-induced hypoalgesia in persons with rheumatoid arthritis

Normalized pressure pain thresholds (PPTs) (means ± standard errors) at the contracting (a) M. quadriceps (segmental exercise-induced hypoalgesia, or EIH) or the distant resting (b) M. deltoideus (plurisegmental EIH) at baseline (base), at start, in the middle (mid) and at the end of a standardized M. quadriceps contraction, before intervention (health-enhancing physical activity, or HEPA) and at 1-year and 2-year follow-ups among 21 participants. Each PPTvalue was normalized and adjusted (by adding a coefficient) so that the baseline values always corresponded to 1. Values above 1.0 indicate higher PPTs during contraction (that is, EIH activation). Abbreviation: SD standard deviation
