WS ST rats. Gait and vertical force and motion. WS ST rats show little to no relation of midthoracic vertical motion and weight support forces compared to the normal rat. A: video measure of height of a fixed point on the rat’s back (mm). B: stance phases of each leg from video (solid bar: stance). Gait involves significant overlap of steps, very long hindlimb stance periods and rarely are only two legs on the ground. C: vertical support forces. Solid line: sensor 1 vertical force measurement. Dotted line: sensor 2 vertical force measurement. Phase I: rat wholly on sensor 1. Only solid line force is non-zero. Phase II spanning sensors. Net vertical force is sum of solid and dotted traces. Phase III: wholly on sensor 2. Only dotted trace is non-zero. Vertical forces do not relate clearly to vertical motion excursion in the back. Abscissa for all plots: time in seconds. RHL : right hindlimb. RFL: right forelimb. LHL: left hindlimb. LFL: left forelimb.
