The effect of autotraction on the configuration of herniated discs was studied by computed tomography. Twenty-five patients with lumbago and sciatic pain were studied by means of GE CT/T8800 scan of the lumbar spine (two lower levels), before and after autotraction. Four patients had CT scans of the L4-L5 and L5-S1 levels during the actual autotraction. For this part of the study a special table was designed to be fitted into the CT scanner. In this way it was possible to study the configuration of the herniated disc during the time the traction force was applied. The results were uniform. In none of the patients could we register any difference in the disc, which retained its herniation. Despite this, good clinical results were obtained after autotraction. Consequently, the effect of autotraction is not connected with any marked change in the configuration of the herniated disc.
通过计算机断层扫描研究了自动牵引对椎间盘形态的影响。对25例腰痛伴坐骨神经痛患者在自动牵引前后进行了GE CT/T8800腰椎（下两个节段）扫描。4例患者在实际自动牵引过程中对L4-L5和L5-S1节段进行了CT扫描。对于该研究的这一部分，设计了一张特殊的检查台以适配CT扫描仪。通过这种方式，可以在施加牵引力时研究突出椎间盘的形态。结果是一致的。在所有患者中，我们均未发现椎间盘有任何差异，其突出状态保持不变。尽管如此，自动牵引后仍取得了良好的临床效果。因此，自动牵引的效果与突出椎间盘的形态没有任何明显变化有关。
