[TED Talk] 5 Thought-Provoking TED Talks By Disabled People – The Life Quadriplegic

TED talks are always fascinating and great at helping you to see things from a new perspective. There are hundreds of thought-provoking talks online given by people from all over the world. Here are a number of great TED talks given by disabled people which I find particularly thought-provoking.

1.     Deep sea diving… in a wheelchair

Sue Austin creates at which helps to express the sense of joy and freedom she feels when using her powerchair. She created an underwater wheelchair which allows her to glide effortlessly past coral reefs and schools of fish. I would love to try something like that!

2.     I’m not your inspiration, thank you very much

Comedienne and journalist Stella Young talks about how society often sees disabled people as “inspiring” just for getting out of bed in the morning. Inspiration porn objectifies disabled people and makes it seem like our only purpose is to inspire able-bodied people. Stella explains why this is wrong in this funny talk.

3.     When we design for disability, we all benefit

Elise Roy is a former disability rights lawyer and is now a design thinker. In this talk she discusses how people with disabilities see the world from a different perspective, and this perspective allows them to solve problems in ways that other people wouldn’t have thought of. She says: “When we design for disability first, you often stumble upon solutions that are better than those when we design for the norm.”

4.     Our fight for disability rights – and why we’re not done yet

Judith Heumann talks about her personal role in the fight for disability rights in America. She highlights how far disabled access has come in the last 50 years, but also how far we have still yet to go.

5.     We Are All Designers

John Hockenberry, a journalist, talks about how living a life of intent can help us to make our lives our own. We can take what we are given in life, such as our disabilities, and put our own spin on it such that our lives are not defined by our disabilities. We can create a new story to cover up the old one. Something better.

[WEB SITE] Neurorobotic hand exoskeleton restores grasp function to quadriplegics

A consortium of European scientists has successfully restored grasp function to six quadriplegics using a non-invasive hybrid brain-neural hand exoskeleton. The system was developed by researchers at the University of Tübingen, Germany, The BioRobotics Institute at the Scuola Superiore Sant’Anna, Italy, and the Guttmann Institute in Spain. The study participants were able, for example, to eat and drink independently at a restaurant. While it was commonly assumed that outside-the-lab brain-machine interface(BMI)-based restoration of hand function would require surgical implantation of neural electrodes, the study – now featured in the inaugural issue of Science Robotics – used electric brain activity recorded from the scalp, thus avoiding any surgical procedure.

The Tübingen researchers say the new approach will significantly improve quality of life after high cervical spinal cord injury or stroke. The system translates brain electric activity and eye movements into hand opening and closing motions, restoring intuitive grasp function to an almost normal level, the study shows. Thanks to portable and wireless hardware integrated into a wheelchair, participants could freely move and use the system in their everyday life environment.

Surjo Soekadar, the responsible physician and lead author of the study, says the technology can be adapted to do even more: “Next, we are planning the development of intelligent, context-sensitive and cosmetically unobtrusive neurorobotic systems which patients can mount on their bodies entirely unassisted”.

Besides the immediate improvement in the ability to perform activities of daily living as shown by the European research consortium, recent clinical studies suggest that repeated use of such brain-controlled exoskeletons could induce neurological recovery after spinal cord injury or stroke. This BMI-related neuroplasticity, as Dr. Soekadar underlines, may also become a powerful tool to treat neuropsychiatric disorders, such as depression or cognitive disorders which currently represent the third leading cause of global disability-adjusted life years (DALY), i.e. the total number of years lost to illness, disability, or premature death. While large-scale clinical trials will be required for further validation, the system introduced by Dr. Soekadar and his colleagues may now pave the way for such long-term and out-of-the-lab studies.

[WEB SITE] Surgeons restore hand, arm movement to quadriplegic patients –  Washington University in St. Louis

 

 

 

Innovative technique helps patients with neck injuries

October 8, 2015

Washington University physician Michael Bavlsik, MD, shows surgeon Ida Fox, MD, how he can now grip an otoscope, which he uses in his practice. He is one of nine quadriplegic patients who regained some hand and arm movement after nerve-transfer surgery, a procedure pioneered at Washington University School of Medicine. Fox, an assistant professor of surgery, operated on Bavlsik.

A pioneering surgical technique has restored some hand and arm movement to patients immobilized by spinal cord injuries in the neck, reports a new study at Washington University School of Medicine in St. Louis.Like railroad switchmen, the focus is on rerouting passageways; however, instead of trains on a track, the surgeons redirect peripheral nerves in a quadriplegic’s arms and hands by connecting healthy nerves to the injured nerves. Essentially, the new nerve network reintroduces conversation between the brain and the muscles that allows patients, once again, to accomplish tasks that foster independence, such as feeding themselves or writing with a pen.The researchers assessed outcomes of nerve-transfer surgery in nine quadriplegic patients with spinal cord injuries in the neck. Every patient in the study reported improved hand and arm function.The study is published in the October issue of the American Society of Plastic Surgeons’ journal Plastic and Reconstructive Surgery.“Physically, nerve-transfer surgery provides incremental improvements in hand and arm function. However, psychologically, these small steps are huge for a patient’s quality of life,” said the study’s lead author, Ida K. Fox, MD, assistant professor of plastic and reconstructive surgery. “One of my patients told me he was able to pick up a noodle off his chest when he dropped it.’ Before the surgery, he couldn’t move his fingers. It meant a lot for him to clean off that noodle without anyone helping him.”
