Clinical prospective, random study.
Analyze the results of the six-minute walk test (6MWT) in patients with adolescent idiopathic scoliosis.
Although it is widely believed that Adolescent Idiopathic Scoliosis (AIS) causes cardiorespiratory dysfunctions, there is no report in literature of objective measurements of this restriction in the ventilatory performance during physical exertion.
One hundred twenty-six adolescents matched by gender and age were prospectively studied at a tertiary teaching institution: 40 patients without spine deformities (group I-controls), and 86 patients with AIS with a spine curve ranging from 45 degrees to 138 degrees (group II). All patients underwent radiographic evaluations and the 6MWT.
Normal controls presented significantly lower mean heart rate and Borg scores, as well as higher oxygen saturation and walked longer distances on the 6MWT.
The 6MWT effectively demonstrated the cardiorespiratory restrictions presented by patients with AIS.

分析青少年特发性脊柱侧凸患者六分钟步行试验（6MWT）的结果。
虽然普遍认为青少年特发性脊柱侧凸（AIS）会导致心肺功能障碍，但目前尚无文献报道在体力活动中对通气性能的这种限制进行客观测量。
在一所三级教学医院，我们前瞻性地对 126 名性别和年龄匹配的青少年进行了研究：40 名无脊柱畸形患者（I 组-对照组）和 86 名脊柱曲线范围从 45 度到 138 度的 AIS 患者（II 组）。所有患者均接受了影像学评估和 6MWT。
正常对照组的平均心率和 Borg 评分明显较低，血氧饱和度较高，6MWT 行走距离较长。
6MWT 有效地证明了 AIS 患者存在心肺功能限制。
