The Mathematical Modeling of the Human Gait with Ankle Hinged Orthosis
RESUMO
The mathematical model of the human gait with ankle hinged orthosis is built. The spring block is built-in into the orthosis design in order to increase unloading effect. The system of 9 rigid bodies (trunk and two two-link feet) joined by the cylindrical hinges is used for modeling. The active muscles forces and orthosis spring elastic forces are acting together in the orthosis joint. The elastic parameters stiffness optimization problem in order to minimize maximum value of the active forces torque (over double stride interval) in the orthotic joint is investigated. The methodology of the approximate solution construction of the formulated problem based on the generalized coordinates parametrization by the set of cubic smoothing splines, the inverse dynamic approach and numerical methods of the nonlinear mathematical programming is developed.
