WS ST rats. Center of Pressure motion: lateral deviations of CoP over time. This shows most time is spent at the lateral extremes of CoP motion compared to normal rat which only briefly exhibits lateral CoP motion. The calculated mediolateral deviations of the center of pressure from the line of travel are plotted through time (measured in seconds). Stance phases are plotted above. Solid line : on sensor 1. Dotted line: on sensor 2. Patterns are variable. Two examples are shown. Panel A: rat with considerable systematic deviations of about 2cm each side. Panel B: rat with asymmetric (note: scalloped pattern) slowly varying deviations over time. Grey shaded region: Phase II when CoP calculation was not trustworthy in this arrangement.
