Representative stabilogram-diffusion plots from a subject. It shows two SDA plots of both SDD ON and SDD OFF conditions. The slopes of lines fitted to both short-term region (Ds,AP) and long-term region (Dl,AP) are less steep while SSD was on. The critical point coordinates (Δtc,AP, 〈Δr2〉c,AP) are both smaller when SSD ON.
