A new method of conservative treatment for low back pain (LBP) was studied by follow-up investigation of 382 patients during the last five years. The attempt to reduce repetitive impulsive intervertebral impact in the troublesome S1-L5-4 area by significant improvement of the foot's attenuational capacity through artificial viscoelastic shock absorbing was prompted by the authors' work on decreased capability of LBP spines to attenuate axially propagated walking stresses. Viscoelastic shoe inserts were used in addition to light flexible shoes as artificial shock absorbing devices. Maximal amplitudes of bone oscillation during walking were reduced by about 40% by the viscoelastic inserts. Rapid and surprisingly significant improvement of pain syndrome and patient mobility occurred in about 80% of the patients. The accelerographic patterns recorded on a sacrum of patient with LBP were unusual for a healthy subject; they usually disappeared after treatment in LBP cases. Results suggested that poor walking impact attenuation was a true cause for prolonging intervertebral structures overstrain and consequent degeneration. It seemed logical that as spine damage could be explained primarily by prolonged impulsive overstrain, treatment must include viscoelastic inserts which increase foot shock absorbing capacity and help cushion the spine.
在过去五年中，通过对382例患者的随访调查，研究了一种治疗腰痛（LBP）的保守新方法。作者发现，LBP脊柱减弱轴向传播的行走应力的能力下降，促使他们尝试通过人工粘弹性减震显著提高足部的减震能力，以减少S1-L5-4区域反复出现的脉冲性椎间冲击。除了轻便灵活的鞋子外，还使用了粘弹性鞋垫作为人工减震装置。粘弹性鞋垫使行走过程中骨骼振荡的最大振幅降低了约40%。约80%的患者疼痛综合征和患者活动能力迅速且惊人地显著改善。记录在LBP患者骶骨上的加速度图模式对于健康受试者来说是不寻常的；在LBP病例中，这些模式通常在治疗后消失。结果表明，行走冲击衰减不佳是导致椎间结构过度劳损并进而退变的真正原因。由于脊柱损伤主要可由长期的脉冲性过度劳损来解释，因此治疗必须包括能增加足部减震能力并有助于缓冲脊柱的粘弹性鞋垫，这似乎是合乎逻辑的。
