World News – UA – New device may benefit patients with upper limb paralysis


Tiny device the size of a small paperclip has been shown to help upper limb palsy patients text, email and even shop online in the first human trial

The device, Stentrode ™, has been successfully implanted in two patients, both of whom have severe paralysis due to amyotrophic lateral sclerosis (ALS) – also known as motor neuron disease (MND) – and none of both had the ability to move their upper limbs

Published in the Journal of NeuroInterventional Surgery, the results showed that the Stentrode ™ was able to wirelessly restore the transmission of brain impulses outside the body This allowed patients to successfully perform daily tasks such as banking online, shopping and texting, which previously were not available to them

Professor Peter Mitchell of Royal Melbourne Hospital, director of the neurointervention service and principal investigator of the trial, said the results were promising and demonstrate that the device can be implanted and used safely in patients

This is the first time that an operation of this type has been performed, so we cannot guarantee that there would be no problems, but in both cases the surgery went better than we had hoped « 

Professor Mitchell implanted the device on study participants through their blood vessels, adjacent to the motor cortex of the brain, in a procedure involving a small « keyhole » incision in the neck

« The procedure is not easy, in each surgery there were differences depending on the patient’s anatomy, but in both cases the patients were not able to leave the hospital until a few days later, which also demonstrates the rapid recovery from surgery « Said Professor Mitchell

Neurointerventionalist and CEO of Synchron – the research business partner – associate professor Thomas Oxley said this is a watershed moment for the field of brain-computer interfaces

« We are delighted to announce that we have delivered a fully implantable, take-home wireless technology that does not require open brain surgery, that works to restore freedoms for people with severe disabilities, » Associate Professor Oxley, who is also co-head of the University of Melbourne’s vascular bionics laboratory, said

Both patients used the Stentrode ™ to control the computer operating system, in combination with an eye-tracker for cursor navigation This meant they didn’t need a mouse or keyboard

They also underwent machine learning-assisted training to control multiple mouse click actions, including zoom and left click.The first two patients achieved 92% and 93% average click accuracy, respectively, and typing speeds of 14 and 20 characters per minute with predictive text turned off

University of Melbourne Associate Professor Nicholas Opie, co-director of the University’s vascular bionics laboratory and founding technological director of Synchron, said the developments were exciting and the patients involved had returned to a level of freedom in their life

« Watching participants use the system to communicate and control a computer with their minds independently and at home is truly amazing, » Associate Professor Opie said

« We are grateful to work with such fantastic participants, and my colleagues and I are honored to make a difference in their lives. Hope others are inspired by their success

« For the past eight years, we have called on some of the world’s leading minds in medicine and engineering to create an implant that allows paralyzed people to control external equipment with the power of thought We are happy to announce that we have achieved this goal « 

The researchers warn that while there are still a few years before the technology, capable of restoring independence to accomplish daily tasks, is publicly available, the global, multidisciplinary team is working tirelessly to make it a reality. reality

The trial recently received a $ AU148 million grant from the Australian Commonwealth Government to expand the trial to hospitals in New South Wales and Queensland, in hopes of enrolling more patients
