Effect of vestibular electrical stimulation on the H-reflex.

A study was made of changes of exitability of the H-reflex m. solei under electrical stimulation of the labyrinth in hemiparetic patients with focal ischaemic lesion of the brain. In contrast to healthy persons, the potentiating effect of electrical stimulation of the labyrinth has a longer latency, a clearly lower amplitude and is protracted in time (we may say that the facilitating or potentiating effects are not well synchronized). The results are being interpreted on the basis of our research material and literary data obtained for the most part on experimental animals.
