-A custom report for the pirouette was generated in Visual3D. The pirouette report contains four pages to compare different signals for the right and left leg. The Inclination angle for the pirouette on each leg from which we can analyze how well the subject kept their center of mass over the foot which is a key aspect of a successful pirouette. A smoother curve close to zero would be the goal for the dancer. The angular momentum in the Z direction (vertical axis) with a greater angular momentum is desired by the dancer. The X, Y and Z Center of Gravity position with a better pirouette having as smooth curves as possible for all three directions. Lastly, the report visualizes the X, Y and Z ankle angles. To interpret this further more analysis was done in **Sift**. +A custom report for the pirouette was generated in Visual3D.

 Several statistical analysis methods are available in Sift for further data exploration. To identify differences in leg kinematics between dominant and non-dominant legs [[sift:statistical_parametric_mapping|SPM (statistical parametric mapping)]] was used to identify pirouette phases with statistically different behaviour. \\ \\ Several statistical analysis methods are available in Sift for further data exploration.

-The following plot shows a comparison of model angular momentum for left and right leg spins. Similar to the inclination angle only one slight moment of significance can be observed. Especially with theses instances occurring at different points of the spin for these two signals. \\+The following plot shows a comparison of model angular momentum for left and right leg spins.
