| Outline of Final Research Achievements |
This study reports on an analysis of the deformation and stress on an orthosis using its 3D shape data and finite element analysis software. The analysis is based on orthosis load data obtained from ambulatory data of healthy participants and orthosis users. First, the forces acting on an orthosis during ambulation of participants were measured using a six-axis force torque sensor installed in the calf section. The data revealed that there is a significant difference in anterior-posterior loads, which may be an important evaluation index of orthotic ambulation, between orthosis users and healthy participants. These data were applied as an external force to the orthosis shape obtained using a scanner and subjected to finite element analysis. Then, we analyze stress concentrations and deformations of orthoses modified by trimming when a given load was applied to them.
