Fig. 2

Systolic blood pressure (BP) change (black line) and Center of Pressure (CoP) amplitude in medial-lateral (ML) direction (dotted line) of a representative patient during supine position and over 3 min after postural change. The light grey arrow represents the moment of maximum BP change, while the light grey closed circle and open circles represent respectively the CoP during and the CoP before and after maximum BP change. The dark grey arrow represents the moment of maximum CoP movement, while the dark grey closed circle and open circles represent respectively the BP change during and the BP change before and after maximum CoP movement
