Temperature vs. time curves obtained from thermal imaging data during baseline, i.e. before performing the isometric exercise and 5 min after the isometric exercise separated by a red vertical line. (Subjects were required to press every 2 seconds, and for a total of 2 minutes, the dynamometer handle, at the 20% of previously assessed maximal individual strength.) measured from: (a) 14 ROIS for HCs subject, (b) 14 ROIS for PsA subject, (c) the randomly chosen representative ROI2 for HCs subject, and (d) the randomly chosen representative ROI2 curve for PsA subject.
