The first-of-its-kind clinical trial used novel stimulation technology to restore the sense of touch and movement to 45-year-old Keith Thomas, who was paralysed from the chest down in 2020 after diving into a swimming pool.
After living as a quadriplegic for more than a year, Mr Thomas was approached by the Feinstein Institutes for Medical Research in the US to take part in a study that proposed a double neural bypass to re-route signals from the brain in order to restore movement and sensation.
Artificial intelligence was able to re-link his brain to his body through microchips implanted into his brain during a 15-hour surgical procedure.
“This is the first time the brain, body and spinal cord have been linked together electronically in a paralysed human to restore lasting movement and sensation,” said Chad Bouton, a professor at the Institute of Bioelectronic Medicine at the Feinstein Institutes, who led the clinical trial.
“When the study participant thinks about moving his arm or hand, we ‘supercharge’ his spinal cord and stimulate his brain and muscles to help rebuild connections, provide sensory feedback, and promote recovery. This type of thought-driven therapy is a game-changer.”
Over 100 million people around the world currently live with some form of paralysis or movement impairment, with the scientists hopeful that the new method could provide new pathways toward improving the condition of many of them.
Mr Thomas has already regained more than double his arm strength since enrolling in the clinical trial, and also reported feeling sensations in his forearm even when the system was switched off.
“There was a time that I didn’t know if I was even going to live, or if I wanted to, frankly,” said Mr Thomas.
“Now I can feel the touch of someone holding my hand. It’s overwhelming.”
