Moment Based Parameterization of Cyclograms of Slope Walking

The problem under study is the moment based parameterization of a series of gradually evolving cyclograms The cyclograms correspond to natural humanwalk on a variable inclination treadmill with slope varying from to at each interval Parameterization of cyclograms has several useful applications including the diagnosis of pathological gait For this study we consider the planar hip angle knee angle cyclograms although the described method is fairly general in nature and may be used without restriction for any closed curve such as the phase diagrams and the moment angle diagrams Moreover the method can be extended to higher dimensions and thus we can treat cyclograms involving three or more joint angles Moment based identi cation of physical objects is a topic of active research in the eld of pattern recognition We perform the necessary adaptations of these techniques to use them in biomechanics
