在正常人行走期间同时测量胫骨和头骨中的脚跟撞击时的瞬时加速度，显示出峰值为λ。穿硬跟时分别为0.5g和0.5g。弹性鞋跟使振幅减半，而回弹可以通过包括粘弹性聚合物插入物的结构来避免。瞬态传播的行波（和向外）的骨骼，其不显眼的外观在力板的研究是由于不均匀和非同步加速度的身体的各个部分。这些研究结果的影响，包括脚跟罢工瞬态骨关节炎变性的潜在贡献。背痛患者的症状加重可能是由于他们在骨旁组织中引起的剪切。可能的生理作用的瞬变提到。
Simultaneous measurements during normal human walking of the transient acceleration on heel strike in the tibia and skull show peaks of .apprx. 5 g and 0.5 g respectively when hard heels were worn. Resilient heels halved the amplitudes, while rebound could be avoided by a construction including a viscoelastic polymer insert. The transient is propagated as travelling waves up (and outwards from) the skeleton, its inconspicuous appearance in force plate studies being due to the non-uniform and non-synchronous acceleration of various parts of the body. Implications of these findings are noted, including the potential contribution of heel strike transients to osteoarthritic degeneration. Aggravation of symptoms in sufferers from back troubles may be due to shear induced by them in para-osteal tissue. Possible physiological roles for the transients are mentioned.
