BACKGROUND

The aim of this study was to quantitatively analyze quite standing postural stability of adolescent idiopathic scoliosis (AIS) patients in respect to three sensory systems (visual, vestibular, and somatosensory).

METHOD

In this study, we analyzed the anterior-posterior center of pressure (CoP) signal using discrete wavelet transform (DWT) between AIS patients (n = 32) and normal controls (n = 25) during quiet standing.

RESULT

The energy rate (∆E %) of the CoP signal was significantly higher in the AIS group than that in the control group at levels corresponding to vestibular and somatosensory systems (p < 0.01).

CONCLUSIONS

This implies that AIS patients use strategies to compensate for possible head position changes and spinal asymmetry caused by morphological deformations of the spine through vestibular and somatosensory systems. This could be interpreted that such compensation could help them maintain postural stability during quiet standing. The interpretation of CoP signal during quiet standing in AIS patients will improve our understanding of changes in physical exercise ability due to morphological deformity of the spine. This result is useful for evaluating postural stability before and after treatments (spinal fusion, bracing, rehabilitation, and so on).

背景

本研究旨在定量分析青少年特发性脊柱侧凸（AIS）患者在三个感觉系统（视觉、前庭和本体感觉）方面的静立位姿势稳定性。

方法

本研究使用离散小波变换（DWT）分析了 AIS 患者（n=32）与正常对照组（n=25）在安静站立时的前-后中心压力（CoP）信号。

结果

与对照组相比，AIS 组的 CoP 信号的能量率（∆E%）在与前庭和本体感觉系统对应的水平上显著升高（p<0.01）。

结论

这表明 AIS 患者通过前庭和本体感觉系统来补偿可能由脊柱形态畸形引起的头部位置变化和脊柱不对称。这可以解释为这种补偿可以帮助他们在安静站立时保持姿势稳定。对 AIS 患者在安静站立时 CoP 信号的解释将有助于我们理解由于脊柱形态畸形导致的身体运动能力的变化。该结果有助于评估脊柱融合、支具、康复等治疗前后的姿势稳定性。
