摘要:

目的 探讨噪声前庭电刺激(nGVS)对青少年特发性脊柱侧凸(AIS)患者静止站立时姿势控制、椎旁肌激活程度和对称性,以及大脑皮质激活水平的影响。

方法 2023年12月至2025年6月,于中山大学附属第一医院招募符合要求的AIS患者30例,在稳定和不稳定平面上进行静止站立任务时分别施加nGVS、伪刺激和无刺激。同步采用三维测力台测量静止站立时压力中心(COP)的位移面积、内-外向与前-后向位移长度和速度,无线表面肌电图测量上端椎、顶椎和下端椎水平双侧椎旁肌的均方根和凸/凹侧激活比,功能性近红外光谱测量双侧背外侧前额叶(DLPFC)、辅助运动区、运动前区、初级感觉皮质和初级运动皮质的活动。

结果 相较于伪刺激和无刺激条件,nGVS降低AIS患者静止站立时的COP位移面积(F = 4.645, P = 0.006, η²p = 0.138),内-外向位移长度(F = 7.651, P = 0.001, η²p = 0.209)和速度(F = 5.035, P = 0.010, η²p = 0.148);提高顶椎凹侧椎旁肌均方根值(F = 6.486, P = 0.003, η²p = 0.183),降低凸/凹侧激活比(F = 4.028, P = 0.023, η²p = 0.122);提高双侧DLPFC激活水平(F > 6.718, P < 0.01, η²p > 0.188)。中介效应分析存在nGVS-DLPFC-凸/凹侧激活比-COP位移面积的路径(P < 0.05)。

结论 nGVS可能通过增强双侧DLPFC激活,提高椎旁肌对称性,从而改善AIS患者的姿势控制能力。

Abstract:

Objective To investigate the effect of noisy galvanic vestibular stimulation (nGVS) on postural control, paraspinal muscle activation and cortical activation of patients with adolescent idiopathic scoliosis (AIS) during quiet standing.

Methods A total of 30 eligible participants with AIS were recruited from the First Affiliated Hospital of Sun Yat-Sen University between December, 2023 and June, 2025, and finished upright standing tasks on both stable and unstable surfaces under nGVS, sham and no stimulation conditions. They were synchronously measured sway area (SA), medial-lateral and anterior-posterior sway length (SLMLand SLAP) and velocity (VMLand VAP) of center of pressure (COP) with three-dimensional force platform; the root mean square (RMS) of the bilateral paraspinal muscles at upper end vertebra, apical vertebra and lower end vertebra levels were measured with wireless surface electromyography, and convex/concave activation ratio was calculated; and cortical activation of bilateral dorsolateral prefrontal cortex (DLPFC), supplementary motor area, premotor cortex, primary somatosensory cortex and primary motor cortex were measured with functional near-infrared spectroscopy.

Results Compared to the sham and no stimulation conditions, nGVS significantly reduced SA (F= 4.645, P= 0.006, η²p = 0.138), SLML(F = 7.651, P= 0.001, η²p = 0.209) and VML(F= 5.035, P= 0.010, η²p = 0.148); increased the RMS of paraspinal muscles on the concave side of the apical vertebra (F= 6.486, P= 0.003, η²p = 0.183), and decreased its convex/concave activation ratio (F= 4.028, P= 0.023, η²p = 0.122), and enhanced activation of bilateral DLPFC (F> 6.718, P <0.01, η²p > 0.188). The mediation analysis confirmed a significant path of nGVS-DLPFC-convex/concave activation ratio-COP displacement (P< 0.05).

Conclusion nGVS may improve postural control in patients with AIS by enhancing DLPFC activation and ameliorating paraspinal muscle imbalance.
