Summary of the VOR recovery for the GVS vs. the non-GVS group. The VOR responses were compared by averaging the values across frequencies. We observed marked differences in improvement across the time course between the UL with (the GVS group) and without GVS intervention (the non-GVS group), as indicated by Gain (A), Phase (B), and Symmetry (C). The recovery of VOR responses in the GVS group was significantly faster than the non-GVS group from POD 3, and this trend was maintained until POD 14. VOR, vestibulo-ocular reflex; GVS, galvanic vestibular stimulation; UL, unilateral labyrinthectomy; POD, postoperative day. **p < 0.01; ***p < 0.001.
