简要总结
The aim of the study is to investigate the effectiveness of a new rehabilitation technology for paralysis that occurs after stroke or spinal cord injury. The research will jointly use a prototype neurorehabilitation orthosis, in which a robotic device moves a paralyzed arm at the command of a non-invasive brain-computer interface to perform a game life-like task augmented using a virtual-reality display, as well as an electrical stimulation device that activates the spinal cord and/or muscles of the paralyzed arm.
Investigators expect that a portion of the patients participating in the study will have an improvement in arm mobility by the end of the study.
Participants who express their special written consent will have venous blood tests conducted three times for subsequent analysis of lipid biomarkers, in order to further evaluate the effectiveness of rehabilitation methods based on biochemical analysis.
详细描述
The aim of the study is to investigate the effectiveness of a new rehabilitation technology for paralysis that occurs after stroke or spinal cord injury. The research will jointly use a prototype neurorehabilitation orthosis, in which a robotic device moves a paralyzed arm at the command of a non-invasive brain-computer interface to perform a game life-like task in virtual reality (for example, aiming a hand-held virtual toy gun at a target), as well as an electrical stimulation device that activates the spinal cord and/or muscles of the paralyzed arm.
The study is carried out to collect data on the role of central and spinal mechanisms in the plasticity of neuronal circuits that determine the effect of combined spinal neurostimulation and robotic rehabilitation under the control of non-invasive neural interfaces in patients in early and late rehabilitation period after acute cerebrovascular accident and in patients after trauma of the cervical and upper thoracic spinal cord.
The study will use two technologies - neural interfaces and transcutaneous electrical stimulation of the spinal cord. Neural interfaces are a rapidly developing area at the intersection of medicine, neuroscience, biology, engineering, robotics, physics, mathematics, and materials science, which aims to reproduce and supplement brain functions and correct these functions in cases of neurological lesions. The possibility of using neural interfaces for the treatment of neurological disorders, including disorders resulting from spinal cord and brain injuries, epilepsy, strokes, and neurodegenerative diseases, such as Parkinson's disease, has been demonstrated.
Transcutaneous spinal cord stimulation (tSCS) is a method for non-invasive control of the activity of human spinal neural networks used to restore locomotor functions after spinal cord injury (SCI). The published research results show that tSCS modulates the activity of not only spinal but also cortical neuronal networks.
It is expected that the use of tSCS in conjunction with the use of neural interfaces will increase the effectiveness of neural interfaces for the rehabilitation of neurological lesions, including stroke, and SCI.
