University of Pittsburgh researchers have developed a brain-computer interface (BCI) technology is an emerging therapeutic option for those suffering from motor dysfunction due to stroke, amputation, spinal cord injury, or neurodegenerative diseases.
Description
Currently, BCI systems are limited in the range and flexibility of movements for paralyzed individuals, therefore hindering natural and complex movements. This invention outperforms standard BCI systems by eliminating the need for explicit recalibration; instead, calibrating based on kinematic information. The technology has the potential to provide neural prostheses with fast and flexible switching between different behaviors, similar to real arm movements.
Applications
Motor function restoration
Stroke
Amputation
Spinal cord injury
Neurodegenerative disease
Advantages
Current brain-computer interface technologies are particularly limited in their ability to provide a wide range of movements for motor-impaired individuals. This innovative technology overcomes this limitation through its simplified BCI calibration for different tasks and the use of neural activity to determine movement intention and rapidly update decoder parameters. Furthermore, this proposed BCI outperforms standard systems by eliminating the need for explicit re-calibration and kinematic information, allowing for more natural movements. This technology will have significant implications for the clinical viability and widespread use of BCI systems for restoring limb motor function and touch, greatly enhancing the usability of impending clinical systems and contribute to advancing neurotechnologies for individuals who are paralyzed.
