Quantification model for muscular forces and momentums in human lower extremities.
The possibility of calculating muscular forces and momentums and their influence on skeleton was evaluated in this study by means of computerized tomography performed on a living person. Through this, the surface and corrected surface for each muscle cross section area were obtained, the distance from muscular centroide to the neutral bone axis was measured, and muscular force and muscular momentum on the bone were determined. Muscular momentum on the bone was obtained by multiplication of the muscular force and the distance between muscular centroide and neutral bone axis. The use of computerized tomography, as a method for creating a model for quantification of muscular forces and momentum, was proven to be reliable according to exactness in evaluation of all human lower extremity structures which is the basis for muscular biomechanical characteristic calculations.
