A series of experiments were performed on eight whole, cadaveric lumbar spines and on eight male volunteers to determine whether axial rotation changed with subjects bending forward compared with being in a neutral posture and whether rotation was affected by articular tropism. Kirschner wires were inserted into the spinous processes of the eight cadaveric lumbar spines, and the axial rotation of the wires was measured while the spine was rotated in a torsion apparatus. Similarly, Steinmann pins were inserted into the spinous processes of L3, L4, and L5 of the eight volunteers, and the axial rotation of the pins was measured while the subjects rotated in a torsion apparatus. Axial rotation was found to be less when combined with forward flexion, and articular tropism did not influence the amplitude of rotation.
对八个完整的尸体腰椎和八名男性志愿者进行了一系列实验，以确定与处于中立姿势相比，向前弯曲时轴向旋转是否发生变化，以及旋转是否受关节发育异常的影响。将克氏针插入八个尸体腰椎的棘突中，在脊柱在扭转装置中旋转时测量针的轴向旋转。同样，将斯氏针插入八名志愿者L3、L4和L5的棘突中，在受试者在扭转装置中旋转时测量针的轴向旋转。发现与前屈结合时轴向旋转较小，并且关节发育异常不影响旋转幅度。
