Researchers at the Feinstein Institutes for Medical Research have made significant strides in restoring both movement and sensation to individuals living with paralysis. Led by engineer Chad Bouton, the team has developed a groundbreaking system that utilizes a “double neural bypass” to reroute signals around damaged nerves, enabling individuals to regain the ability to feel and move.
The innovative procedure was first implemented on Keith Thomas, who became paralyzed from the chest down following a diving accident in 2020. In 2023, surgeons implanted two sets of computer chips in Thomas’s brain. One set is designed to detect movement-related signals, while the other delivers sensory information back to the brain. This dual approach allows for direct communication between the brain and muscles, bypassing the injured spinal cord, as well as enhancing remaining neural connections to improve responsiveness.
From the onset of this treatment, Thomas experienced remarkable results. During initial sessions, he reported feeling sensations in his index finger, a significant breakthrough for someone who had lost that ability. The procedure involves extensive teamwork from engineers, therapists, and researchers who guide patients through therapy sessions aimed at refining the system and improving mobility.
The technology employs artificial intelligence to interpret brain signals related to movement. Small sensors placed on the fingers and palm transmit touch sensations back to the brain, creating a feedback loop that enhances the user’s control over their movements. Over time, Thomas has shown notable advancements, including the ability to lift a cup of water to his mouth independently—an achievement that marks a key milestone in his rehabilitation.
Notably, Thomas’s journey extends beyond the confines of the lab. After a year of intensive therapy, he has regained sufficient strength and sensation to experience daily activities at home, such as petting his dog and lifting his arm without assistance.
This pioneering research suggests that paralysis may not be a permanent condition for many individuals. As the double neural bypass technology continues to evolve, there is hope that it could become a widely available treatment, offering new possibilities for independence to those affected by spinal cord injuries. Each small achievement, from feeling a loved one’s hand to performing everyday tasks, underscores the potential of medical advancements in improving quality of life for individuals with paralysis.
