Watch As Spinal Device Allows Paralyzed Man To Move His Legs
Epidural electrical stimulation involves implanting an electrode array along the lower part of the spinal cord, which ordinarily controls movement of the hips, knees, ankles and toes. Unlike similar approaches, the electrodes aren’t being used to directly stimulate the muscles. Instead, they act to reengage the spinal cord’s local nerve network, which doesn’t require input from the brain to carry out basic motor functions. The researchers surmised that this stimulation, combined with sensory input such as stepping on a treadmill could lead to movement.
In the latest study four candidates were chosen, Kent Stephenson, Andrew Meas and Dustin Shillcox. All four had experienced their spinal cord injuries at least two years prior to the study, and two of them were considered to have no chance of recovery.
