In this second of three papers, the principles of a non-invasive in vivo method to quantitatively evaluate the shock absorbing capacity of the human musculoskeletal system and the correlation of this shock absorbing capacity with low back pain (LPB) symptoms are presented. The experiments involved patients suffering from low back pain (as well as other degenerative joint diseases) and healthy patients. The obtained results reveal that low back pain correlates with the reduced capacity of the human musculoskeletal system between the femoral condyle and the forehead to attenuate incoming shock waves. Examination of the absolute values of the amplitude of the propagated waves leads to the conclusion that the human locomotor system, which possesses reduced attenuation capacity, tries to prevent overloading of the head from insufficiently attenuated shock waves. Results of the present investigation support the idea that the repetitive loading resulting from gait generates intermittent waves that propagate through the entire human musculoskeletal system from the heel up to the head. These waves are gradually attenuated along this course by the natural shock absorbers (bone and soft tissues). Contemporary methods for examination of the human musculoskeletal system may by improved by using the proposed non-invasive in vivo technique for quantitative characterization of the locomotor system's shock absorbing capacity.
在这三篇论文的第二篇中，介绍了一种非侵入性体内方法的原理，该方法用于定量评估人体肌肉骨骼系统的减震能力，以及这种减震能力与腰痛（LPB）症状的相关性。实验涉及患有腰痛（以及其他退行性关节疾病）的患者和健康患者。获得的结果表明，腰痛与股骨髁和前额之间的人体肌肉骨骼系统减弱传入冲击波的能力降低有关。对传播波振幅绝对值的检查得出结论，衰减能力降低的人体运动系统试图防止头部因冲击波衰减不足而过载。本研究结果支持这样一种观点，即步态产生的重复负荷会产生间歇性波，这些波从脚跟一直传播到头部，贯穿整个人体肌肉骨骼系统。这些波在这个过程中会被天然减震器（骨骼和软组织）逐渐衰减。通过使用所提出的非侵入性体内技术对运动系统的减震能力进行定量表征，可以改进当代人体肌肉骨骼系统的检查方法。
