A pilot study of ten individuals with adolescent-onset idiopathic scoliosis demonstrated that a week of Cotrel traction and exercises did not improve curve correction obtained by the application of an elongation, derotation, flexion (EDF) cast. There was, however, a significant improvement on lateral bending correction during this period. A prospective, randomized, controlled clinical trial showed that the exercise programme and not the traction was responsible for rendering the spine less rigid.
一项针对10名青少年特发性脊柱侧弯患者的初步研究表明，为期一周的 Cotrel 牵引和锻炼并未改善应用伸展、去旋转、屈曲（EDF）支具所获得的侧弯矫正效果。然而，在此期间侧弯矫正有显著改善。一项前瞻性、随机、对照临床试验表明，是锻炼计划而非牵引使脊柱的僵硬程度降低。
