Research Project C03 (2nd period)

C03-1 The relationship between body consciousness and motor control aspects of body representation in the brain

Research Outline

In this study, we aim to determine the relationship between the two aspects of body representation in the brain: somatognosia and motor control. We study patients to identify the recovery courses of somatognosia and motor control during rehabilitation, and explore the underlying neural mechanisms.

C03-2 Motor Skill Training/Analysis of brain plasticity Through Muscle Contraction Pattern-Based Direct Rehabilitation

Research Outline

Extensive and focused physiotherapy is needed to help individuals with disabilities, such as hemiplegics, achieve natural physical movement involving the simultaneous use of various muscles. This project aims to develop a new method for bilateral communication of joint motions, muscle cooperative patterns, forces, and joint impedance between the therapist and patient. We also try to understand the brain plasticity through motor skill training with our support method.

C03-3 Study on kinesthetic illusion induced by visual stimulation under the mixed reality and brain functional connectivity

Research Outline

We have developed a system to replace the subject’s own limb with an artificial body under the mixed reality given to the subject who is resting. The subject in a resting state can be induced kinesthetic illusion, as if the subject’s own body is moving, during the artificial body movement is shown. The aim of the present study is to clarify a change of the brain functional connectivity after repetitively the kinesthetic illusion was applied.

C03-4 Development of comprehensive measurement system of balance function to monitor the effect of rehabilitative interventions.

Research Outline

In this study, we aim to advance a comprehensive understanding of the body’s balance maintenance systems based on our previous work by measuring balance using the relationship between the center of gravity (COG) and center of pressure (COP) during stepping movements. We are planning to first observe the COG–COP relationship during physical activity or in response to perturbation and to then compare any observed differences to the subjects’ etiologies or brain lesion locations. Our final goal is to develop a comprehensive system for measuring balance function to monitor the effects of rehabilitative interventions and clarify the modifications to the motion control mechanisms during the reacquisition of the ability to balance.

C03-5 Effect of “Hybrid-Neurorehabilitation to improve Sense of Agency” for patients with stroke hemiplegia

Research Outline

Following are the aims of the present study: (1) to quantitatively evaluate multisensory integration function and explicit and implicit sense of agency in patients with hemiplegia after stroke; (2) to investigate the relationship between sense of agency and severity and recovery from hemiplagia in a cross-sectional/longitudinal study; (3) to investigate the effect of Hybrid-Neurorehabilitation that improves adaptive motor learning and sense of agency.
