Researchers from Providence, R.I.-based Brown University have developed a technology that restores a form of sensory feedback in patients with complete spinal cord injuries, according to a March 10 WJAR 10 report.
The study, conducted in partnership with the Providence VA and Rhode Island Hospital, also in Providence, involved implanting electrodes above and below the injury site in three participants with no sensation below the point of injury. These electrodes delivered electrical signals the patients learned to associate with limb positions, effectively simulating the feeling of movement.
Traditionally, electrical stimulation has helped paralyzed patients regain some movement, but not sensation. The new approach allowed participants to experience what researchers call “replaced sensation,” helping them track limb positions without relying solely on visual cues.
Participants underwent the procedure over two weeks and expressed a strong desire to take the system home. Researchers plan to expand the study with more participants and eventually develop a take-home version of the device, according to the report.
