作者研究了４８７例无症状青少年特发性脊柱侧弯患者肺通气功能，并以正常同龄青少年２５０例作对照。结果表明：患者肺活量，肺活量占预计值百分比，深吸气量，用力肺活量，１秒钟用力呼气容积，最大通气量，最大通气量占预计值的百分比较同龄正常组明显降低；而潮气容积，１秒钟用力呼气容积占用力肺活量比值，最大呼气中段流量，最大呼气中段流量占预计值的百分比与对照组无显著性差异。并进一步研究表明：肺活量占预计值的百分比的降低与脊柱侧弯的Ｃｏｂｂ角、侧弯顶椎的椎体楔变度及旋转度发病年龄有关，而与脊柱侧弯方向无关。
The authors studied pulmonary aeration in 487 asymptomatic adolescent patients with idiopathic scoliosis and compared 250 adolescents with normal adulthood. The results showed that the vital capacity, vital capacity, percentage of predicted value, deep inspiratory capacity, forced vital capacity, forced expiratory volume per second, maximum ventilation and maximum ventilation were significantly lower than those of the normal age group. , 1 second forced expiratory volume occupancy capacity of the vital capacity, the maximum expiratory flow in the middle, the maximum expiratory flow in the middle of the predicted percentage of the predicted value with the control group no significant difference. And further studies have shown that the decrease in the percentage of vital capacity predicted is related to the Cobb angle of scoliosis, the vertebral body wedge deformity and the age of onset of rotation, but not to the direction of scoliosis.
