Measure of Mechanical and Thermal Hyperalgesia. Comparison of the sham and capsaicin condition for (row a) mechanical and (row b) thermal pain rating for the CHEPs (white background) and LEPs session (grey background) separately. The condition (sham and capsaicin) is illustrated on the x-axis. In (row a) the y-axis illustrates the difference in overall pain rating, which is calculated by subtracting the pre-cream from the post-cream pain. In (row b) the y-axis illustrates average pain rating during the sessions. Subjects’ responses of both conditions are connected by a grey line.
