Thousands of people suffer spinal cord injuries in car accidents every year. Technologies and therapies that make use of sensors and impulses in order to trigger movement point to the way forward in spinal cord injury treatment. A recent study also broke new ground in this field.
The experiment was conducted on 17 persons who had no spinal injury. These persons were made to wear special fitting headgear that measured their brain impulses. They were asked to extend their legs or think about extending them. The researchers then recorded brain waves to identify when a subject moved his leg and intended to move his leg.
The researchers found that the brain waves were very similar in both the actual movements as well as the imagined movements. Using these electrodes, the researchers were able to identify when people were thinking about moving their leg even when they were not actually doing so, based on the brain waves recorded. These people were able to move their legs just by thinking about moving it, helped by the triggering of electrical impulses in the spinal cord.
