A study was conducted to investigate the criterion validity of measures of upper extremity (UE) motor function derived during practice of virtual activities of daily living (ADLs). Fourteen hemiparetic stroke patients employed a Virtual Occupational Therapy Assistant (VOTA), consisting of a high-fidelity virtual world and a Kinect™ sensor, in four sessions of approximately one hour in duration. An...
To assist a large number of physically disabled people who no longer are in full possession of their body motion, we have been developing an exoskeleton robot (ExoRob) to rehabilitate and to ease upper limb motion since movement of shoulder, elbow, and wrist play a vital role in the performance of essential daily activities. The proposed ExoRob will be comprised of seven degrees of freedom to enable...
The Rutgers Arm II system consists of a low-friction tilting table, a vision-tracked forearm support, a PC and a large display. Patients play a number of custom Java 3D games using their affected arm while supported by- or resisted by gravity through the table tilting. Four chronic post-stroke subjects (between 6 months and 5 years following stroke) trained for 12 half-hour rehabilitation sessions...
This study aimed at investigating and quantifying the time course of abnormal synergies in the affected upper limbs of chronic stroke patients treated with a neuro-rehabilitation robot. Eight age-matched normal and seven chronic stroke patients were recruited to perform rectilinear tracking movements in four directions for four months. Kinematic, kinetic and electromyographic (EMG) data were used...
In this paper the trajectory tracking control of the arm rehabilitation robot for stroke patients is investigated by an interactive robust control approach. The functions of patients' voluntary joint torques are designed depending on the motion ability of their arms, and the dynamic model of the human-robot system is presented. Based on the dynamic model, an interactive controller is designed to provide...
The Rutgers Arm II trains primarily shoulder motor control, arm dynamic response, endurance and cognitive anticipatory strategies in virtual environments. It improves on our earlier Rutgers Arm by replacing magnetic tracking with a visual tracking and by the use of a training table that tilts. Pilot trials with a single subject showed clear dependency on table tilt angle. Further trials are ongoing.
