Robotic system can help paralyzed patients regain hand movement

New Delhi: Scientists have developed a system that can read brain signals to help users control an artificial hand just by thinking — an advance that could help stroke patients regain the ability to move their fingers. Spinal injuries or stroke often leaves a person partially paralysed. Such disabilities leave them disconnected from their families and community.

“We want to give them a life where, using the technology, they can fulfill their basic needs, such as getting a glass of water or typing on the screen,” said Dr Haider Raza, from University of Essex in the UK, one of the scientists who worked on the system. The team, which includes researchers from Indian Institute Technology (IIT) Kanpur, developed a brain-computer interface (BCI) that can ‘read’ a person’s brain waves and convert them to computer signals.
