Repetitive impact loadings of the musculoskeletal system have been linked to the development of osteoarthritis and low back pain. An important function of footwear is to attenuate foot-ground impacts. The purpose of this study was to measure the effects of footwear types upon the impact ground reaction forces and the transient stress waves transmitted up the lower limb. The results have shown that both transient stress waves and ground reaction forces are affected by footwear during walking. Furthermore, with harder midsoles footwear, higher shock was transmitted to the lower extremities. This paper confirms the importance of using footwear to cushion the impact generated at heelstrike during walking. It also reveals that both shock and force measurements are required to evaluate and prescribe footwear to patients suffering from impact-related chronic diseases.
肌肉骨骼系统的重复性冲击负荷与骨关节炎和腰痛的发展有关。鞋类的一个重要功能是减轻足部与地面的冲击力。本研究的目的是测量鞋类类型对地面冲击反作用力以及沿下肢向上传播的瞬态应力波的影响。结果表明，在行走过程中，瞬态应力波和地面反作用力都会受到鞋类的影响。此外，中底较硬的鞋类会将更高的冲击力传递到下肢。本文证实了使用鞋类来缓冲行走时脚跟触地产生的冲击力的重要性。它还表明，需要同时进行冲击力和力的测量，以便为患有与冲击相关慢性病的患者评估和开具鞋类处方。
