"Gentlemen, we can rebuild him. We have the technology. We have the capability to make the world's first bionic man. Steve Austin will be that man. Better than he was before. Better... stronger... faster."

When actor Lee Majors' Steve Austin character became the world's first bionic man in the 1970s television show The Six Million Dollar Man, the technology was still largely considered to be in the realm of science fiction. But incredible advances in the intervening decades have made the dream of bionic body parts an exciting reality for people who have sustained debilitating injuries.

In this blog post, we explore the development of bionic technology, including the planned testing of a bionic spine, and explain how the concept of neuroplasticity and brain re-training is revolutionizing health care.

From Science Fiction to Reality

Brain-computer interfaces have been developed over many years to help meld the human mind with machine. Recent breakthroughs include using signals recorded within the brain to move robotic arms; harnessing movement intentions within paralyzed persons to allow them to use a wireless tablet; and the development of the cochlear implant – the most widely used and well-known bionic device used by people with certain types of hearing impairment.

The most advanced of these technologies are "bi-directional" in nature, a type of interface that records brain activity and movement intentions while also stimulating the nervous system to act. However, many of the implanted devices using this technology either require significant and infection-prone surgeries such as a craniotomy or have a limited life-span (for example, electrodes implanted into the brain lose their effectiveness when scar tissue begins to grow). External devices like electrode caps or robotic suits are often impractical. However, news of upcoming human trials of bionic spines has been lauded by researchers as the "holy grail" of brain computer interface technology.

What Is The Bionic Spine?

Only 3 centimetres in length, the bionic spine is a stent-electrode (stentrode) device that would be fed through a catheter into blood vessels leading into the brain and positioned over the motor cortex. Once placed, the stentrode would read and translate brain signals into commands that are transmitted via Bluetooth technology into bionic limbs.

The bionic spine would not serve to repair damaged pathways, but rather to provide an alternate route or conduit for brain messages to travel. Prior to implanting the device, doctors would record brain signals while asking patients to complete certain tasks or to think about movement. When the device is implanted to this area of activity in the brain, it would provide the brain signals with a bypass to activate bionic parts of the lower body.

Although researchers expect patients will initially have to concentrate to achieve movement, eventually the technology may be refined to a point where even subconscious thought can prompt desired action. The first human trials will be occurring this year and focusing on persons with lower body paralysis. However, researchers suggest if the technology proves successful, patients with conditions such as Parkinson's disease, epilepsy, and obsessive compulsive disorder may also benefit from it.

Neuroplasticity: The Amazing Power of the Brain to Heal

By harnessing the brain's neuroplasticity – the formation of new neural connections within the brain to connections lost to injury or disease, the new generation of bionic devices is giving people with debilitating conditions new hope of recovery and rehabilitation.

Having represented many clients with traumatic brain injuries, Howie Sacks and Henry is delighted to have been a presenting event sponsor of "Understanding the Healing Brain: How Neuroplasticity Is Changing The Way Brain Injury Survivors Find Help and Hope." This full day conference, held on May 24, 2017 at Toronto's Marriott Bloor Yorkville Hotel, brought together survivors, caregivers, and members of the legal, medical and insurance communities to learn about recent research in this exciting field and to hear from guest speaker Dr. Norman Doidge, author of The Brain's Way Of Healing.
