We present an at-home assessment system for upper extremity rehabilitation with simple motion capture that is functional and affordable. This system uses lighted targets to initiate a reach to grasp (or touch, if the patient is unable to grasp) to three touch- and force-sensitive cones. During the reach, end-point reach trajectory is captured using a low-cost, custom-built infrared motion capture...
This paper outlines our work in developing a series of game-like VR scenarios to assess and rehabilitate System with 3-D Exercise Machine for Upper Limb, coordination, range of motion and other relevant perceptual motor activities. The novel experiments with a new perturbation paradigm were designed to study the control of hand orientation and arm movement during 3D reach-to-grasp in both human subjects...
A previous design of a biofeedback system for Neurorehabilitation in an interactive multimodal environment has demonstrated the potential of engaging stroke patients in task-oriented neuromotor rehabilitation. This report explores the new concept and alternative designs of multimedia based biofeedback systems. In this system, the new interactive multimodal environment was constructed with abstract...
While BMI systems abound, little care has been exercised over practical considerations in the day to day use of such systems. This paper proposes to learn a Start-Stop switch to augment a directional BMI. Taken together, the hope is that a BMI could be constructed that would be able to signal the appropriate directional intent when called upon and be virtually silent when not needed. Using data from...
In order to compare brain-imaging measurements from different subjects, brain-mapping algorithms are commonly used to register individual brain onto a standardized brain atlas. In this study, SPM99 was used to linearly and nonlinearly coregister a spatially standardized T2-weighted template of C57BL/6J to the atlas by Paxinos and Franklin (2001), local accuracy of between atlas and template was evaluated,...
