Figure 1. Pressure Pain thresholds of the finger and shoulder pre- and post-HUT. Panel A shows healthy controls, panel B ME/CFS patients without fibromyalgia and panel C ME/CFS patients with fibromyalgia. HUT: head-up tilt test; PPT: pressure pain thresholds.
Figure 2. Temporal summation on the finger and shoulder pre- and post-HUT for HC, ME/CFS patients without and with fibromyalgia. For clarity of the figure mean +/- SEM are shown. Panel A shows the windup for the finger and Panel B for the shoulder. The slopes within the groups (pre- and post-HUT) were not statistically significant.
FM: fibromyalgia, +: with; -: without; HC: healthy controls; pre: before head-up tilt test; post: after head-up tilt test
Figure 3. Delta windup (stimulus 10 minus stimulus 1) pre- and post-HUT in healthy controls, in ME/CFS patients without fibromyalgia and in ME/CFS patients with fibromyalgia. Panel A shows the windup for the finger and Panel B for the shoulder.
FM: fibromyalgia; HUT: head-up tilt test
