Vestibular system galvanization in man: the effect of stimulation field changes on the angle of body mass centre displacement.
During monopolar monoaural galvanization the absolute value of body mass centre displacement angle did not depend on the stimulation electrode position. The angle value was always close either to 0 degrees or to 180 degrees (i.e. in the latero-lateral direction). However, some fine angle differences between different electrode positions occurred and they were statistically significant in two cases. During monoaural bipolar stimulation the body mass centre moved practically in all directions (for all four used electrode positions) and the angles formed a more or less coherent rosette in the range of 0 degrees-360 degrees.
