The recent availability of the Kinect sensor, a cost-effective markerless motion
capture system (MLS), offers interesting possibilities in clinical functional
analysis and rehabilitation. However, neither validity nor reproducibility of
this device is known yet. These two parameters were evaluated in this study.
Forty-eight volunteers performed shoulder abduction, elbow flexion, hip abduction
and knee flexion motions; the same protocol was repeated one week later to
evaluate reproducibility. Movements were simultaneously recorded by the Kinect
(with Microsoft Kinect SDK v.1.5) MLS and a traditional marker-based
stereophotogrammetry system (MBS). Considering the MBS as reference,
discrepancies between MLS and MBS were evaluated by comparing the range of motion
(ROM) between both systems. MLS reproducibility was found to be statistically
similar to MBS results for the four exercises. Measured ROMs however were found
different between the systems.
