Researchers at Duke University studied rats who had a disease similar to Parkinson’s.
They attached an electrical stimulation device to their spinal cords, and found when turned it on the animal’s tremors stopped and they began acting like healthy rats.
The study lasted six weeks. During those six weeks the rats’ symptoms significantly improved. Researchers also found evidence that important brain cells were protected from damage that typically occurs in Parkinson’s.
Only a few studies in humans have been done.
Researchers are hoping to conduct larger trials soon. And they went to test the device for other neurological diseases.
