Neurotechnology Provides Near-Natural Sense of Touch

Neurotechnology Provides Near-Natural Sense of TouchRevolutionizing Prosthetics program achieves goal of restoring sensation

A 28-year-old who has been paralyzed for more than a decade as a result of a spinal cord injury has become the first person to be able to “feel” physical sensations through a prosthetic hand directly connected to his brain, and even identify which mechanical finger is being gently touched.

The advance, made possible by sophisticated neural technologies developed under DARPA’s Revolutionizing Prosthetics points to a future in which people living with paralyzed or missing limbs will not only be able to manipulate objects by sending signals from their brain to robotic devices, but also be able to sense precisely what those devices are touching.

Student working to restore walking in people with spiral cord injury

Published: January 28, 2015

Ashley DalrympleThe Rick Hansen Foundation reported 86,000 people in Canada living with a spinal cord injury. Ashley Dalrymple, who hails from Wetaskiwin, is a student at the University of Alberta conducting research to help patients struggling with such injuries.

Dalrymple is a masters of science student based in the Faculty of Medicine and Dentistry and holds an undergraduate degree from the U of A in electrical biomedical engineering. Soon she will be transferring to a PhD program to continue her work. Her current research project uses a technology invented by the university lab she is working in, called intraspinal microstimulation (ISMS).

Paralyzed rats regain use of hind legs with flexible spinal cord implant. Humans to...

Published: January 13, 2015

flexible e-Dura implantSwiss scientists demonstrated a flexible ribbon-like implant that attaches itself to a paralyzed rat’s spinal cord, allowing the animal to walk again. The prosthetic, described by foremost experts in the field as ‘remarkable’, works by delivering timed electrical impulses and drugs along the spinal cord. In this particular case, rats aren’t that different from humans, and true enough clinical trials are now one step closer. In the future, paralysis might just be another word for “walking funny.”

Monkeys Steer Wheelchairs With Their Brains, Raising Hope for Paralyzed People

Monkeys Steer Wheelchairs With BrainsWASHINGTON, D.C.—Experimental wheelchairs and exoskeletons controlled by thought alone offer surprising insights into the brain, neuroscientists reported on Monday.

New technologies offer a window into how the brain creates movement.

Best known for his experimental exoskeleton that helped a paralyzed man kick the opening ball for June’s World Cup in Brazil, Duke University neuroscientist Miguel Nicolelis presented the latest “brain-machine interface” findings from his team’s “Walk Again Project” at the Society for Neuroscience meeting.

Striking the cord: Optical control of motor functions

Lu-Anikeeva-Fiber-Probe-mitGrad student Chi Lu and colleagues demonstrate a highly flexible polymer probe for triggering spinal-cord neurons with light and simultaneously recording their activity.

MIT researchers have demonstrated a highly flexible neural probe made entirely of polymers that can both optically stimulate and record neural activity in a mouse spinal cord — a step toward developing prosthetic devices that can restore functionality to damaged nerves.

There’s hope for the paralyzed – thanks to bionic technology

Published: October 11, 2014

wheelchairTechnologies have long been focused on making it possible for paralyzed people to move again, particularly after the famous ‘Superman’ actor Christopher Reeve died 10 years ago. Although there’s no magic cure for it as of yet, Reeve’s son claims that the efforts made in the past decade would have definitely made him ‘excited’.

Brain-computer interfaces, electrical stimulation, exoskeletons and pharmaceutical therapies have made their mark in terms of restoring the mobility, and certain other functions of paralyzed individuals.

Prosthetics Are Telling Paralyzed Legs How to Walk Again

Published: September 24, 2014

neural-prostheticsNeural prosthetics are getting so good that they can now automatically trigger natural movements in the legs. In a new experiment with paralyzed rats, scientists sent electrical signals to the spinal cord to mimic signals from the brain that could no long reach the limbs. This kind of research could lead to robot-assisted rehabilitation to help people with partial damage to their spinal cords learn to walk again.

Stanford engineer invents safe way to transfer energy to medical chips in the body

Published: May 19, 2014

transfer energy to medical chipsA wireless system developed by Assistant Professor Ada Poon uses the same power as a cell phone to safely transmit energy to chips the size of a grain of rice. The technology paves the way for new “electroceutical” devices to treat illness or alleviate pain.

A Stanford electrical engineer has invented a way to wirelessly transfer power deep inside the body, and then use this power to run tiny electronic medical gadgets such as pacemakers, nerve stimulators or new sensors and devices yet to be developed.

New wheelchair device to prevent pressure sores

Published: February 10, 2014

wheelchair device to prevent pressure soresPressure sores are the leading source of infection, hospitalization and mortality for wheelchair users.

But a new wheelchair sensory system developed through a collaboration with SensiMAT Systems and the University of Toronto’s Professor Milos Popovic is poised to help.

“Take for example, the sad story of Christopher Reeve,” says Popovic. “After his injury Christopher Reeve and his foundation poured millions of dollars into stem cell research. But in the end, he died from a pressure sore that could have been prevented by this inexpensive solution.”

Quadriplegics breathe easier with help of new device

breathing-deviceOnce used by Christopher Reeve, it was developed in part with funding from the Rick Hansen Institute.

Gabriel Abotossaway doesn’t sound like he can’t breathe on his own.

On the phone from his home in Manitoulin Island, the 22-year-old sounds like most men his age. But Gabriel has required help breathing since a 2011 car accident rendered him a high-level quadriplegic. He’s unable to move his diaphragm and breathe independently.
