"Electrode treatment, physical therapy combination lets two paralyzed people walk again
(Reuters Health) - Doctors in Kentucky reported Monday that two of four paralyzed patients were able to walk again with limited assistance after treatment with electrical stimulation to the portion of the spinal cord cut off from the brain, combined with intense physical therapy.
The technique is still experimental and relies in part on implantation of electrodes that seem to prime the largely-dormant part of the spinal cord to listen to faintly-echoed commands by the brain to walk.
"We all walk independent of the brain in a sense because the human spinal circuitry is the primary controller of walking," said Susan Harkema, a leader of the team from the University of Louisville whose report appears online in The New England Journal of Medicine.
Below the level of a spinal cord injury, hundreds of thousands of nerve cells "are still alive and healthy and still connected in a network that controls movement" and allows walking with minimal input from the brain, she told Reuters Health in a telephone interview.
The technique being used by her team re-energizes the walking function, although the patients still need some support because all the information needed to maintain balance - sensory information processed by the brain - still has trouble getting through.
Like the other 1.27 million people paralyzed by a spinal cord injury in the United States, all four volunteers described in the new report were unable to walk or stand. All had been unable to move their legs for at least 2.5 years, although they did have some sensation below the site of their injury.
At least something positive n good fr the application of technologies n sciences instead of the threats of AI taking over the human race!!
Blessed the scientists, researchers, patients n all involved!
To the 2 who still could not walk, may there b some ways to help them. If all else failed, hopefully they know they hv contributed to a significant break through for some other patients who hv a chance to walk now!

Dr. Harkema, who is with the university's Kentucky Spinal Cord Injury Research Center, said one problem is that the electronic stimulator was never designed for this purpose, so it is difficult to adjust on the fly to find the correct frequencies and intensities to sensitize patients to the faint signals coming from the brain.
Medtronic, which makes the stimulator to combat pain, provided the equipment, but no additional support.
The technique does not work in people whose spinal cords have been completely severed, she said.
