Abstract__ Background There is a need to develop cost-effective sensitive stroke assessment instruments. One approach is examining kinematic measures derived from goal-directed tasks which can potentially be sensitive to the subtle changes in the stroke rehabilitation process. This paper presents the findings from a pilot study that uses a computer-assisted neurorehabilitation platform interfaced with a conventional force-reflecting joystick to examine the assessment capability of the system by various types of goal-directed tasks. Methods Both stroke subjects with hemiparesis and able-bodied subjects used the forcereflecting joystick to complete a suite of goal-directed tasks under various task settings. Kinematic metrics developed for specific types of goal-directed tasks were used to assess various aspects of upper-extremity motor .
