Abstract:- The camera system is described for hand movement analysis in Parkinson’s disease. Since lesions in different structures of the central and peripheral nervous systems cause specific disturbances of hand motor function we measure the hand motion trajectory. The patients perform a natural manual transport task (moving an object from one place to another) repeatedly in OFF and ON medicated status and their movement is recorded by two cameras. The 2D trajectories of special markers fixed to the hand are extracted from the image sequences and later on their 3D trajectory is reconstructed from individual views. The described method could be useful for an objective description and quantification of certain hand movement disturbances in Parkinson’s disease.
