Bionic Spine Enables Paralyzed Patients to Walk Again With Thoughts

The bionic spinal cord records brain activity and converts the signals into electrical commands, letting a person move a wheelchair with their thoughts.

A new device called "bionic spine" will enable paralyzed patients to walk again, revealed Australian researchers.

The new device, developed by scientists in Melbourne, is the size of a paper clip and works by allowing patients with spinal injuries to control a robotic limb, an exoskeleton of sorts, just by thinking, Xinhua news agency reported.

New Device Developed That Turns Breath into Words of Severe Paralysis Victims
A new device that gives words to the thoughts could transform the way people with severe muscular weakness or other speech disorders communicate.

‘A tiny device called ‘bionic spine’ will enable paralyzed patients to walk again by allowing them to control bionic limbs with the power of subconscious thought. ’

"What cochlear implants have done for hearing we're trying to do for mobility," said Nicholas Opie, co-principal investigator of the project.

The first human trials of the device will begin next year in patients with lower-limb paralysis first as they have the most to gain from the device.

The device will be placed at the top of the motor cortex, the part of the brain which controls voluntary muscle movement, via a catheter inserted in the jugular vein in the neck.

With the help of this advanced exoskeleton, patients will be able to walk again, go up and down the stairs, sit down and stand up all by themselves.

The electrodes on the outside of the bionic spine will detect signals from the motor cortex and send them to a device implanted in the patient's shoulder which will translate signals into commands telling the bionic limbs to move.

Inserting the device through a vein means patients will avoid brain surgery, reducing any risks involved in the procedure as well as cutting the time required in hospital with the technique requiring only a day procedure.

The therapy involves injecting isolated human embryonic stem cells into the patients to help the body heal on its own in a natural way.

Professor Terrence O'Brien of the Royal Melbourne Hospital is overseeing the project made up of 39 neurologists and biomedical engineers from the hospital, Melbourne University and the Howard Florey Institute of Neuroscience and Mental Health.
