ヒトの下肢骨の衝撃応力波伝播挙動について

抄録

The knee joints of a human being, with the assistance of ligaments and muscles, functionally act as the largest load bearing joints in the movements of the human body, and play an important and indispensable role in the movements and exercises performed by the human body. In such conditioned circumstances, we consider the shock waves generated by human beings at the time of running and jumping to be the waves which travel to the knees through the feet bones, tibia, and fibula, and thereby we apply the impact stress to the shitsumin and san-inko of the focal point in acupuncture, namely the tsubo, and clarify the effect of the stress waves upon the knee joints by employing the highspeed photoelastic analysis in researching the behavior of the propagating impact stress waves. We adopt the shitsumin and san-inko as the working points of the impact stress in order to investigate in what way both of these focal points affect the knee joints and grasp the manner in which they are done. Furthermore we clarify that the long bones such as the lower limbs and upper limbs have their shapes and structural formations to protect the bones from the external forces when they are subjected to the impact stress.
