Fig. 4.
Sensory mapping at baseline tested with metal cool roller. Areas from each patient were transposed to the drawing. Small black circles indicate the superior anterior iliac spine and the pubic tubercle. The red circles indicate the approximate site for maximum palpatory pain (on the pain side), and the red rectangles indicate the outline of the assessment thermode. Blue-shaded polygons indicate individual cool hypoesthesia area. Red-shaded area indicates cool hyperesthesia. (A) Patients with thermal “hyposensitivity” (n = 11). (B) Patients without thermal “hyposensitivity” (n = 10).
