Abstract (EN): This study presents and applies 3D spherical angular analysis in relation with 2D polar coordinates to assess anatomic pelvic movement on modified gait, namely stiff knee (SKG) gait and slow running (SR) comparing with normal gait (NG). Subject specific analysis was performed of an adult healthy male based on inverse kinematics from in vivo and noninvasive capture at human movement lab of reflective markers position from pelvis anatomical selected points with Qualisys camera system during a complete stride of NG, SKG and SR. Radial distance (R), pitch (psi) and azimuth (lambda) angular phases were computed from pelvic angle-angle diagrams (theta(T), theta(C), theta(S)) at transverse (T), coronal (C) and sagittal (S) planes, and angular phase (phi) and planar radial distance (r) polar coordinates computed from pelvic angle-angle diagrams projections at cartesian planes (theta(T), theta(C)), (theta(T), theta(S)), (theta(C), theta(S)). Average radial distances and phase standard deviation were assessed on spherical and polar coordinates.
