The objective of this study was to assess the effect of thoracolumbosacral orthoses (TLSOs) on antero-posterior (AP) sway, medio-lateral (ML) sway and displacement of the center of pressure (COP) during a longitudinal study in patients with adolescent idiopathic scoliosis (AIS).
Eight females aged between 12 and 14.5 years participated in this study. Evaluations were performed prior to the TLSO intervention as a baseline condition, after 1 month, and after 4 months of orthosis use by assessing balance when standing statically on different surfaces.
When standing on both lower limbs on a solid surface there were significant differences in ML sway with the eyes both open and closed, and also in A/P sway but only when standing on a solid surface with the eyes open and also when standing on a foam surface with the eyes closed with TLSO use. When standing on the dominant leg, ML sway significantly improved, but AP sway only improved with a foam base surface with the eyes open.
This study demonstrated positive effects of wearing a TLSO in improving quiet standing balance and standing on the dominant lower extremity in subjects with AIS after 4 months of brace use. Implications for Rehabilitation Due to a change in body shape such as that caused by scoliosis, human posture changes and spinal deformities affect the position of the center of support, and thus balance ability may change. AIS subjects have poor standing stability compared to a healthy matched control group. Brace wearing had positive effect in improving quiet standing balance and standing on the dominant lower extremity in subjects with AIS undergoing brace treatment after 4 months of TLSO use.
本研究的目的是在一项针对青少年特发性脊柱侧凸（AIS）患者的纵向研究中，评估胸腰骶矫形器（TLSO）对前后（AP）摆动、内外侧（ML）摆动以及压力中心（COP）位移的影响。
8名年龄在12至14.5岁之间的女性参与了本研究。在TLSO干预前作为基线条件进行评估，在使用矫形器1个月后以及4个月后，通过评估在不同表面上静态站立时的平衡来进行评估。
当双下肢站立在坚实表面上时，无论睁眼还是闭眼，ML摆动均存在显著差异，AP摆动也有显著差异，但仅在睁眼站立于坚实表面时以及使用TLSO闭眼站立于泡沫表面时存在差异。当单腿站立时，ML摆动显著改善，但AP摆动仅在睁眼且站在泡沫基底表面时有所改善。
本研究表明，在使用支具4个月后，佩戴TLSO对改善AIS患者的安静站立平衡以及单腿站立有积极作用。康复意义由于脊柱侧凸等身体形态变化，人体姿势改变和脊柱畸形会影响支撑中心的位置，进而平衡能力可能发生变化。与健康匹配对照组相比，AIS患者的站立稳定性较差。在使用TLSO 4个月后，佩戴支具对接受支具治疗的AIS患者改善安静站立平衡和单腿站立有积极作用。
