  1. p-location: p value with three-way ANOVA for location differences during all phases.
  2. p-pain: p value with three-way ANOVA for differences between pain-free and maximum pain for both locations of ischemia.
  3. p-interaction pain-location: p value for interaction effects between pain and location of ischemia.
  4. GC Gait Cycle./: Kruskal Wallis test was applied.
