Wrist device delivers electrical pulses to manage Tourette syndrome tics

Researchers at the University of Nottingham developed a wrist device to help people manage Tourette syndrome, a neurodevelopmental condition that usually begins in childhood.

The small device delivers electrical pulses to the median nerve at the wrist. Trials show that this action changes brain activity in areas that control movement. One user of the device is 15-year-old Ollie from Cheshire, who began experiencing involuntary neck movements nearly two years ago.
