運動機構からみた好ましい動作とは

抄録

This article emphasizes the importance of the ‘motion mechanism’ in comprehending human movement and motional impairment. ‘Motion mechanism’ was operationally defined as ‘an effective function against the force of gravity acting on the human body’. To understand human movement, it was necessary to know all the anatomy and human structures, muscle functions and dynamic alignment. As to anatomy and human structure, especially, the axes of human joints had to be clearly understood. And the axes of human joints, there were both physiological and functional axes. In muscle function, muscle physiology, muscle kinetics and the kinetic chain are involved. Dynamic alignment was important in comprehending impairment of the musculoskeletal system. The more severe dynamic malalignment was, the more remarkable the disturbance of movement was. To reduce motor disturbance, re-alignment of dynamic malalignment was effective. One of the methods for re-alignment of the leg during walking and stair-up/down was Knee Bent Walking (KBW). It was used as a conscious method for re-alignment in cases of dynamic malalignment. In the field of physical therapy, as an effective approach for aged, disabled and injured people, it was very important that we understood the motion mechanism and human body functions, and it will offer unlimited possibilities to all aged, disabled and injured people.
