Poststroke motor, cognitive and speech rehabilitation with brain-computer interface: a perspective review

Area of Science:

• Neuroscience
• Biomedical Engineering
• Rehabilitation Medicine

Background:

• Brain-computer interface (BCI) technology offers a direct link between brain activity and external devices.
• Neuroscience research over 20 years highlights BCI's potential in post-stroke rehabilitation.
• BCI systems are explored for motor, cognitive, and communication impairments.

Purpose of the Study:

• To review recent advances in BCI systems for post-stroke rehabilitation.
• To discuss challenges in applying BCI for motor, cognitive, and communication recovery.
• To highlight BCI's role in improving quality of life for paralyzed patients.

Main Methods:

• Review of neuroscientific literature on BCI applications in stroke.
• Analysis of BCI system effectiveness in promoting neuronal recovery.
• Examination of assistive BCI designs for communication and control.

Main Results:

• BCI systems demonstrate promising results in recovering post-stroke motor functions.
• Significant improvements observed in cognitive and language functions through BCI.
• Assistive BCI technologies enhance communication and control for severely paralyzed individuals.

Conclusions:

• BCI technology is a valuable tool for post-stroke rehabilitation across multiple domains.
• Continued research and development are crucial to overcome current BCI challenges.
• BCI systems hold the potential to significantly improve functional independence and quality of life for stroke survivors.
