Outline of Final Research Achievements

This study aimed to establish the basic model of risk assessment of falls and related fractures. Fracture risks with fall conditions were investigated using computed tomography-based finite element analysis (CT/FEA). Bone strength, fracture pattern, and fracture location were analyzed using CT/FEA. The accuracy of the CT/FEA was validated by performing experimental mechanical testing with human cadaveric specimens.
Next, balance function assessment, gait analysis, and motor function assessment were investigated to search fall risk factors. Through these investigations, fundamental data about integrated evaluation of falls and related fractures have been acquired. Based on this study, clinical application for the elderly, patients with osteoporosis, and people with fall risk can be implemented.
