New device shows promise in helping stroke patients regain arm movement

A new device, called the "ear zapper," is being tested to help stroke patients regain arm movement. The trial, led by Sheffield Teaching Hospitals, uses mild electrical pulses to stimulate a nerve in the ear, potentially improving communication between the brain and the arm. Phil Herbert, a stroke survivor, is participating in the trial after struggling with arm weakness since his stroke in 2021. He reports improvements in movement and hopes to regain full use of his right hand after starting the trial in January 2024. The £2.5 million study involves around 240 patients and aims to provide a non-invasive treatment option. Participants use the device for one hour daily, five days a week, over 12 weeks, while performing arm exercises.
