\subsection{Body motion sensing of Kinect: Therapy}  Human motion tracking is widely used for movement analysis within a variety of purposes including rehabilitation and biomechanical representation of human motions \citet{zhou2008human}. Functional assessment has proven to be useful in clinics during rehabilitation \citet{guiraud2012accelerometer}. Currently, most clinical motion analysis centers use a markerbased system (MBS) \citet{zhou2008human}. MBS's data were simultaneously collected from a state-of-the-art stereophotogrammetric system (Vicon, 8 MXT40s cameras, Vicon Nexus software, frequency: 60 Hz) that tracks the spatial trajectories of the reflective markers on the subjects. Marker trajectories were stored on the hard disk for further processing. The marker trajectories allowed for the estimation of joint centers and the definition of 19 segments \citet{capozzo1996position}.
