[TEDx Talks] Can Virtual Reality Ease Post-traumatic Stress Disorder? | Dr. Brenda Wiederhold | TEDxChapmanU – YouTube

Δημοσιεύτηκε στις 2 Σεπ 2015
A licensed clinical psychologist in the U.S. and Europe, a visiting professor at the Catholic University in Milan, and an entrepreneur, Dr. Brenda Wiederhold completed the first randomized, controlled clinical trial to provide virtual reality medical therapy for war veterans suffering from post-traumatic stress disorder (PTSD).
Her most recent achievement is working with coalition troops to provide stress inoculation training prior to deployment. She is further exploring the use of VR in treating patients of all ages suffering from ailments such as claustrophobia to stress disorders. In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized. Dr. Wiederhold is CEO of the Virtual Reality Medical Institute in Belgium and the Executive Vice President of the Virtual Reality Medical Center in California.

[VIDEO] After watching this, your brain will not be the same – Lara Boyd | – YouTube

Published on Dec 15, 2015
In a classic research-based TEDx Talk, Dr. Lara Boyd describes how neuroplasticity gives you the power to shape the brain you want. Recorded at TEDxVancouver at Rogers Arena on November 14, 2015. YouTube Tags: brain science, brain, stroke, neuroplasticity, science, motor learning, identity, TED, TEDxVancouver, TEDxVancouver 2015, Vancouver, TEDx, Rogers Arena, Vancouver speakers, Vancouver conference, ideas worth spreading, great idea, Our knowledge of the brain is evolving at a breathtaking pace, and Dr. Lara Boyd is positioned at the cutting edge of these discoveries. In 2006, she was recruited by the University of British Columbia to become the Canada Research Chair in Neurobiology and Motor Learning. Since that time she has established the Brain Behaviour Lab, recruited and trained over 40 graduate students, published more than 80 papers and been awarded over $5 million in funding. Dr. Boyd’s efforts are leading to the development of novel, and more effective, therapeutics for individuals with brain damage, but they are also shedding light on broader applications. By learning new concepts, taking advantage of opportunities, and participating in new activities, you are physically changing who you are, and opening up a world of endless possibility.

[WEB SITE] Robotics For Stroke Rehabilitation, TEDxHerndon, Dr. Karen Nolan

Dr Karen Nolan TedX Herndon 2016

Dr. Karen Nolan’s Ted Talk at TEDxHerndon from May 2016 has been finally uploaded to YouTube.  In her talk, Dr. Nolan focuses on the rehabilitation needs of post-stroke patients suffering from hemiplegia.  Hemiplegia is a form of paralysis on one side of the body due to brain damage from stroke.

Dr. Karen Nolan is a Senior Research Scientist in Human Performance and Engineering Research at the Kessler Foundation.  You might remember her from her very persuasive and thorough presentation on the Ekso GT as a rehabilitation tool back in February 2016: Stroke Recovery Clinical Trials With Ekso GT

In her TEDxHerndon talk, Dr. Nolan spends more than half of her time focusing on the needs and challenges faced by stroke patients with hemiplegia and hemiparesis (weakness on one side).  She then slowly transitions into the potential of robotics for stroke rehabilitation.

At the 11 minute mark, Dr. Nolan brings up the intensity of her talk to an 11.  She presents a video segment demonstrating real world rehabilitation.  She then compares the classical rehabilitation with that of a robotics device, the Ekso GT.  But this is just the beginning, as Dr. Nolan is an authority on biomechanics.

Dr. Nolan dissects the usefulness of the Ekso GT rehabilitation exoskeleton beyond what can be observed by the naked eye.  In her talk, she presents the muscle activations of a major muscle group with and without the exoskeleton.   Furthermore, she exhibits a full 3D kinematics model of the human body with and without the use of an exoskeleton:

Rehabilitation with and without an exoskeleton, Dr. Karen Nola, 2016, via YouTube

In the image above, you can see a person performing walking with the help of the Ekso GT.  The person is moving towards the screen.  The left hand is supported by a cane.  Both feet are pointing in the correct direction and the step will not be executed until proper weight shift is detected by the exoskeleton.

In the image to the right, the patient is undergoing classical rehabilitation.  One person is holding a cart which supports the left arm.  A second person is manually moving the right leg.  Note that the leg is pointing outwards.  More importantly, and what would be missed by just looking at a video, there isn’t a proper weight distribution.  The person is leaning on the cart with their left arm, and the right foot is being dragged along.  This dramatically decreases the quality of the rehabilitation session.

 

Dr. Nolan concludes her presentation with a suggestion on how robotics for stroke rehabilitation can be improved. She suggests that engineers, medical professionals, patients, and researchers work more closely together.  The goal of this collaboration would be to more closely define who would and wouldn’t benefit from using rehabilitation robotics.  How long should the sessions be and what procedures should be followed?  Amazingly, these are exactly the same challenges listed by Dr. Dylan Edwards in his June presentation at Ekso Bionics:

 

Objective Discussion Of The Ekso GT and Adoption Challenges.

Conclusion:

In her Ted Talk, Dr. Nolan lists the now familiar primary and secondary advantages of using rehabilitation exoskeletons (more specifically the Ekso GT).  She elevates the discussion by presenting videos, muscle activation graphs and 3D models of classical vs. robotic rehabilitation.  This is the strongest objective argument for exoskeleton rehabilitation presented to the public so far.

[VIDEO] MRI scanning to make you feel better | Rainer Goebel – TEDxAmsterdam 2014

…Goebel and his team have developed an advanced software system for the real-time analysis of functional MRI brain scans. He scans the brain and analyzes brain activity in the regions of the brain related to the problem of the patient. The patient is shown this neuro-feedback real-time through a brain-computer interface. Through this feedback, a severely depressed person can visualize how his brain activity influences the way he feels and the way he can control these emotions by personally activating or de-activating activity in relevant parts of his brain, with astonishing results. Goebel also shows us the different neurological responses of different people, from one of the happiest men in the world to a girl with locked-in syndrome…
