噪声电前庭刺激（nGVS）增强前庭系统。压力中心（COP）摇摆已被证明在nGVS期间减少，但nGVS的后效仍不清楚。本研究的目的是阐明nGVS对COP摇摆的后效应。我们将26名参与者随机分配到对照组（假刺激）或nGVS组。所有参与者在基线、刺激期间和刺激后睁眼站立时测量COP摇摆。在nGVS组中，与基线相比，刺激期间和刺激后的摇摆路径长度、内外侧平均速度和前后平均速度均降低。相反，在对照组中没有检测到COP摆动的显著差异。在nGVS组中，刺激效果和后效之间存在相关性，表明nGVS对具有高基线COP摇摆的人有效。
Noisy galvanic vestibular stimulation (nGVS) enhances the vestibular system. The center of pressure (COP) sway has been shown to decrease during nGVS, but the after-effect of nGVS remains unclear. The aim of this study is to elucidate the after-effect of nGVS on COP sway. We randomly assigned 26 participants to either control (sham stimulation) or nGVS groups. All participants were measured for COP sway while standing with open eyes at baseline, during stimulation, and after stimulation. In the nGVS group, sway path length, mediolateral mean velocity, and anteroposterior mean velocity decreased both during stimulation and after stimulation compared with baseline. Conversely, no significant difference in COP sway was detected in the control group. There was a correlation between the stimulation effect and the after-effect in the nGVS group, indicating that nGVS is effective for people with high baseline COP sway.
