Both optokinetic and galvanic vestibular stimulations modulate the position of the centre of pressure (CP) in people with hemiparesis.
The correction action of sensory stimulation for postural asymmetry is more effective in RHL suggesting a high level cortical effect on body’s representation of space.
The effect of both sensory stimulations is significantly correlated suggesting a common or at least overlapping central mechanism in relation to postural control.
