研究设计.特发性脊柱侧凸青少年平衡控制的横断面研究。探讨躯体感觉功能、平衡控制与青少年特发性脊柱侧凸（AIS）之间的关系。平衡控制需要躯体感觉、视觉和前庭输入的贡献。以往的研究表明，异常的体感诱发电位（SSEP）与AIS有关。共有105名年龄在11 - 14岁的AIS女孩和57名正常女孩进入研究，并在减少或冲突的感觉条件下（即，感觉组织测试）。采用单因素方差分析评价脊柱侧凸和体感诱发电位测试的躯体感觉功能对感觉组织测试成绩的影响。15例AIS患者SSEP异常。在正常、减少或冲突的躯体感觉、视觉和前庭条件下测量所有受试者的姿势摇摆。单向方差分析表明，当站立期间对体感、视觉和前庭系统的依赖增加时，脊柱畸形或SSEPs对平衡控制没有显着影响（P > 0.05）。然而，在SSEP异常的患者中，当受试者不得不依赖体感输入来控制平衡时，发现了显著的效果（P = 0.023）。脊柱侧凸本身的影响不显著（P = 1.0）。AIS患者双侧SSEP潜伏期差异显著，提示SSEP异常与AIS有关。SSEP对平衡控制的显著影响的发现进一步表明AIS患者亚组中存在异常躯体感觉功能。
Study Design. A cross-sectional study of the balance control in adolescents with idiopathic scoliosis.Objective. To investigate the relationship among somatosensory function, balance control, and adolescent idiopathic scoliosis (AIS).Summary of Background Data. Balance control requires the contribution of somatosensory, visual, and vestibular inputs. Previous studies have shown that abnormal somatosensory evoked potentials (SSEPs) were associated with AIS.Methods. A total of 105 girls with AIS and 57 normal girls aged 11 - 14 years entered the study, and were evaluated with bilateral tibial nerve evoked cerebral SSEPs and standing balance control under reduced or conflicting sensory conditions (i.e., the sensory organization test). One-way analysis of variance was conducted to evaluate the effects of scoliosis and somatosensory function tested by SSEPs on the performance of sensory organization test.Results. There were 15 patients with AIS who had abnormal SSEPs. Postural sway was measured on all subjects under normal, reduced, or conflicting somatosensory, visual, and vestibular conditions. One-way analysis of variance indicated no significant effect of spinal deformity or SSEPs on the balance control when there was an increased reliance on the somatosensory, visual, and vestibular systems during stance (P > 0.05). However, in the patients with abnormal SSEPs, a significant effect was found when subjects had to rely on somatosensory input for their balance control (P = 0.023). The effect of scoliosis by itself was not found to be significant (P = 1.0).Conclusions. The finding of significantly larger difference in bilateral SSEP latencies in patients with AIS indicated the association of abnormal SSEPs with AIS. The finding of a significant effect of SSEPs on the balance control further indicated the presence of abnormal somatosensory function in a subgroup of patients with AIS.
