Presentation Title: Multimodal Neuroprosthesis System for Home-Based Upper Extremity Rehabilitation
Abstract: The loss of voluntary motor function reduces independence and quality of life. Rehabilitation relies on neuroplasticity and task-specific training, but conventional therapy is labor-intensive, costly, and often inaccessible during the critical recovery period. Functional Electrical Stimulation Therapy (FEST) enhances motor recovery, yet current devices remain inflexible and dependent on manual adjustments. This project describes the development of a multimodal neuroprosthesis system integrating FEST, speech recognition, and computer vision. The system will enable multiple grasp types through a universal stimulation program, allow discrete-vocabulary voice commands for control, and use real-time object recognition to adjust stimulation according to task demands. Usability and interface design will be evaluated with healthy and stroke participants, focusing on latency, recognition accuracy, and user preferences across manual, speech, and vision inputs. The expected contributions include increased autonomy for individuals, support for home-based rehabilitation, reduced healthcare burden, and promotion of independence and quality of life.
