A new study published in the online edition of the journal Science has revealed that scientists have successfully used electric stimulation of brain and spine to make rats with spinal cord injuries that had left their hind legs paralyzed to regain the use of their legs.
The researchers said that the rats underwent intensive training program and electric stimulation of brain and spine that allowed them to regain the use of their paralyzed hind legs.
AdvertisementThe study has led to hopes that the technique could be used in humans but the researchers were quick to point out that it cannot be used in all types of spinal injuries.
The study was conducted by researchers at Federal Institute of Technology in Lausanne who operated on 10 rats and cut down the direct nerve connections to the hind legs but did not completely severe the spinal cord. The rats were then made to undergo an intensive program which included electric stimulation in the brain, spinal cord and chemical stimulation in the wound area.
