Four young men who have been paralyzed for years achieved groundbreaking progress — moving their legs — as a result of epidural electrical stimulation of the spinal cord, an international team of life scientists reports today in the medical journal Brain.
All four participants were classified as suffering from chronic, motor complete spinal cord injuries and were unable to move their lower extremities prior to the implantation of an epidural stimulator. The stimulator delivers a continuous electrical current to the participants' lower spinal cords, mimicking signals the brain normally transmits to initiate movement.
