Modern biomechanical motion analyses visualize sequence of (athletic) movements in their dynamics and complexity. As biomechanical functional imaging they expand the common spectrum of static orthopaedic diagnosis by the dynamical component. Detection of reasons and mechanisms of limitations of movement and injuries demands a problem-oriented analytic approach with regard to basic classes of movements as well as to sports-specific profiles of strains and sports-specific demand profiles. The instrumental gait and run analysis as standard method includes three different supplementary analytical ways of access where kinematics describes the temporal progress of a movement in space, kinetics deals with the effect of strength and moments and electromyography describes time, duration and intensity of muscular activity. Resulting intervention measures primarily should be oriented to individual normality of movement and asymmetries rather than in accordance with a normative exercise.
