Abstract
A new method for analyzing symmetry and normalcy of gait patterns is explained. This method utilizes eigenvectors to compare waveforms. The right and left limbs of a single subject are compared to determine symmetry. To determine normalcy, a single limb from a subject is compared to a normative file created from the average of healthy control subjects. The analysis method provides four measures of symmetry and normalcy: trend phase, trend symmetry/normalcy, range amplitude ratio, and range offset. The trend symmetry/normalcy is a comparison of the shapes of the waveforms for each limb. The range amplitude ratio is a comparison of the range of motion of each limb. The range offset is a comparison of the range in which each limb operates. The exact methods and clinical applications are provided.Mesh：
