Outline of Final Research Achievements

In this research, we aim to develop a new BMI device for body-function reconstruction which strongly felt the sense of agency and the sense of ownership, and to construct a methodology. The research results are as follows.
(1)Through brain activity measurement and psychological experiments, we clarified the following two points: a)By applying sensory feedback to the BMI prosthesis, the user feels a sense of ownership of the prosthetic hands, b)Tactile feedback and somatosensory feedback of the BMI prosthesis enhance sense of agency to the prosthesis
(2) We developed upper-limb neuro-prosthetic hand, finger extension support device, neuromuscular electrical stimulation device controlling paralyzed finger. We applied these devices to 8 patients and revealed that these devices are useful for rehabilitation
