In spatial neglect, the functional benefit of rehabilitation methods is subject to debate. A few studies have reported that galvanic vestibular stimulation (GVS) is efficacious in spatial neglect. The objective of the present study was to establish whether the effects of GVS persist after the end of stimulation.
Four patients with pathological rightward deviation in a bisection task at least three months after right hemisphere stroke. A single-blind, randomized crossover design was used to assess the effects of GVS on performance in line bisection and star cancellation tasks under three different conditions (cathode-right, cathode-left and sham stimulation).
There were no significant differences in the performance of either task following GVS (relative to sham stimulation).
Galvanic vestibular stimulation did not reduce spatial neglect symptoms in any of the stimulation conditions. Further studies are necessary to understand the disparity between our results and those reported in the literature. Repeated sessions, a higher current intensity and/or alternating-current stimulation may improve this method before it can be used clinically.
在空间忽视症中，康复方法的功能效益存在争议。一些研究报告称，电前庭刺激（GVS）对空间忽视症有效。本研究的目的是确定刺激结束后GVS的效果是否持续存在。
四名右半球中风至少三个月后在二等分任务中存在病理性向右偏斜的患者。采用单盲、随机交叉设计，在三种不同条件（阴极在右、阴极在左和假刺激）下评估GVS对直线二等分和星形删除任务表现的影响。
GVS后（相对于假刺激），两项任务的表现均无显著差异。
在任何刺激条件下，电前庭刺激均未减轻空间忽视症状。有必要进一步研究以了解我们的结果与文献报道结果之间的差异。在临床应用之前，重复治疗、更高的电流强度和/或交流电刺激可能会改善这种方法。
