| Research Abstract |
The aim of this study is to elucidate the mechanism of hip fracture, which is one of the cause of bedridden, and discuss its prevention. A multibody/finite element hybrid model was constructed to reconstruct the body motion during walking and fall of elderly. Using this model, fall simulations by faint, slip, trip and step down during walking were conducted and factors increasing risks of hip fracture were evaluated. Then simulations taking account of the arm movement were conducted and evaluate the effectiveness of protective action for fracture prevention quantitatively.
