Idiopathic scoliosis (IS) is characterized by a three-dimensional deviation of the vertebral column and its etiopathogenesis is unknown. Various factors are associated with idiopathic scoliosis, among these a prominent role has been attributed to integration of vestibular information with graviception for perception of space. Subjective visual vertical (SVV) is a sensitive sign of verticality perception. The aim of this study was to determine if SVV in adolescents with IS is different from healthy controls. Examination of SVV was performed using the bucket method. Binocular measurements of SVV were made in 23 adolescents with IS (age 14.5 ± 2.5, mean ± SD) and 23 healthy subjects (age 14.0 ± 2.9). The groups differed significantly on SVV deviation (p < 0.01): healthy controls (-0.04° ± 0.64°), IS group (0.86° ± 1.39°). There was also significant difference in SVV uncertainty (p< 0.001): healthy controls (1.50° ± 0.94°), IS group (2.46 ± 0.82°). We conclude that the perception of visual vertical is altered in IS which may play role in development of IS.
特发性脊柱侧凸（IS）的特征是脊柱的三维偏差，其病因不明。各种因素与特发性脊柱侧凸有关，其中前庭信息与重感整合在感知空间方面起着重要作用。主观垂直视觉（SVV）是垂直感知的敏感标志。本研究旨在确定 IS 青少年的 SVV 是否与健康对照组不同。使用桶法进行 SVV 检查。对 23 名 IS 青少年（年龄 14.5 ± 2.5，平均值 ± SD）和 23 名健康受试者（年龄 14.0 ± 2.9）进行了 SVV 的双眼测量。两组在 SVV 偏差上有显著差异（p < 0.01）：健康对照组（-0.04° ± 0.64°），IS 组（0.86° ± 1.39°）。SVV 不确定性也有显著差异（p < 0.001）：健康对照组（1.50° ± 0.94°），IS 组（2.46 ± 0.82°）。我们得出结论，IS 中垂直视觉的感知发生了改变，这可能在 IS 的发展中起作用。
