Four different types of derotation braces and an elastic knee support were tested on ice-hockey players. The elastic support did not noticeably affect rotation and abduction-adduction of the knee. All four braces reduced rotation and abduction-adduction in test actions simulating sports situations. Flexion-extension was slightly affected by two of the individually made braces in one action. Running a figure eight was slower with two of the individually made braces. The best braces, one individually made and one ready-made, limited rotation and abduction-adduction effectively, but did not affect performance. Minor differences in design may account for differences in effect and may alter the protection afforded by a brace.
对冰球运动员测试了四种不同类型的旋转矫正护具和一种弹性护膝。弹性护膝对膝关节的旋转和外展 - 内收没有明显影响。在模拟运动场景的测试动作中，所有四种护具都减少了膝关节的旋转和外展 - 内收。在一个动作中，有两种定制护具对屈伸有轻微影响。使用两种定制护具进行“8”字跑时速度较慢。效果最佳的两种护具，一种是定制的，一种是成品，能有效限制旋转和外展 - 内收，但不影响运动表现。设计上的细微差异可能导致效果不同，并可能改变护具提供的保护作用。
