The balance system senses head motion via the balance organs and stabilises vision during head movements. Without it, your vision becomes blurry when your head moves and can be severely disabling. This system can self-repair after injury, but that varies between patients. We have developed a rehabilitation technique shown to reliably improve self-repair. This project consists of 13 individual experiments that will help us better understand how the balance system can be trained to improve using our new rehabilitation technique and device.
