...regained some sensation and motion throughout his body, thanks to a regimen that included being suspended by harness over a treadmill while therapists moved his legs through a walking gait. The therapy, known as locomotor training, was said to take advantage of the fact that the spinal cord is hardwired with a sort of backup program for walking, one that can take over when signals from the brain quit...
...most of what a patient has left. It's less helpful when the spine is completely severed--by, say, a gunshot. This prevents the brain from getting any signals downstream. But most injuries are not so complete. As long as some links are present, so is potential. "The spinal-cord networks become optimized for the new situation," Harkema says, "and the brain changes as well." As that happens, entire lives--many that have just begun--change...
...April 20, 1999 Richard Castaldo, then 17, was eating lunch on the lawn with Rachel Scott when Harris and Klebold attacked. They killed her and shot him in the arm, chest, back and abdomen, damaging his lungs, kidney and spleen. A spinal cord injury will confine him to a wheelchair for life...
...research, but for neurodegenerative diseases, the scientists at Harvard and Columbia disagree. “No one has been able to differentiate those cells into motor neurons,” Eggan said. “For some reason, the adult stem cells that you can isolate in the spinal cord have lost their ability to do that. You have to have a more embryonic source.” —Staff writer Clifford M. Marks can be reached at cmarks@fas.harvard.edu...
...believe in is creating life for the sole purpose of destroying it. We gain a great deal by medical research and the good news is that the politicization of the stem cell issue probably is not even necessary, because recent discovers have shown that stems cells from the umbilical cord may in fact be as useful as the embryonic stem cells that were previously created...
