Techniques and Methods for Testing the Postural Function in Healthy and Pathological Subjects

Figure 2

The disturbance of one (a) or two (b) sensors leads to an increase in the sensory contribution of other sensors (not disturbed) in postural regulation. The disturbance is indicated by a star-shaped sign while the increase in sensory contribution is indicated by an arrow.

(a) Disturbance of one sensory sensor

(b) Disturbance of two sensory sensors
