The goal isn't necessarily to learn how to play "Flight of the Bumblebee" — it's so patients with spinal cord injuries can improve feeling or movement in their hands, as Markow explains it to Georgia Tech News. In a new study, patients practiced playing the piano for 30 minutes three times a week for eight weeks. But they also wore the glove at home for two hours a day, five days a week, only feeling the vibration and not playing any instrument. A control group learned the piano, but didn't wear any gloves. Ultimately, in a series of grasping tests, the glove group performed much better.
