Student-built wheelchair runs indefinitely on solar power

Student-built wheelchair runs indefinitely on solar power | Longevity science | Scoop.it

A solar-powered wheelchair designed by students at the University of Virginia has won first prize in a competition, Change My Life in One Minute, to mark World Cerebral Palsy Day. Entrants to the competition were asked to come up with an innovation that could make a significant difference to a person with a disability. The solar-powered wheelchair can run continuously powered only by the sun.

Gel-coated implants could reverse paralysis caused by nerve damage

Gel-coated implants could reverse paralysis caused by nerve damage | Longevity science | Scoop.it

When a nerve in the peripheral nervous system is torn or severed, it can take a long time to regenerate – if it does so at all. Depending on the location of the injury, it can leave the affected part of the patient’s body numb and/or paralyzed for years, or even for the rest of their life. Now, however, scientists from Israel’s Tel Aviv University have created a gel and an implant that they claim could vastly aid in the healing of damaged nerves.

 

The implant is a tiny pliable biodegradable tube, that is placed around the two cut ends of the nerve. It serves to line them up with one another and hold them together end-to-end, plus its inner surface is coated with the gel.

Mindwalker mind-controlled exoskeleton could help the disabled walk again

Mindwalker mind-controlled exoskeleton could help the disabled walk again | Longevity science | Scoop.it

The Mindwalker (or Mind-controlled orthosis and VR-training environment for walk empowering) project proposes that the damaged spinal cord be bypassed altogether, instead routing brain signals directly to a robotic exoskeleton in a bid to get patients back on their feet. Its development involved researchers collaborating across several European countries.

Quadriplegic woman gets chocolate fix using thought-controlled robotic arm

Quadriplegic woman gets chocolate fix using thought-controlled robotic arm | Longevity science | Scoop.it

Earlier this year, a 58 year-old woman who had lost the use of her limbs was successfully able to drink a cup of coffee by herself using a robotic arm controlled by her thoughts via a brain computer interface (BCI). Now, in a separate study, another woman with longstanding quadriplegia has been able to feed herself a chocolate bar using a mind-controlled, human-like robot arm offering what researchers claim is a level of agility and control approaching that of a human limb

Chiba robotic wheelchair turns wheels into legs

Chiba robotic wheelchair turns wheels into legs | Longevity science | Scoop.it

Making a wheelchair that can deal with steps and other obstacles has puzzled engineers for decades, with everything from tank treads to spokes tried and found not quite practical.

 

Now a team of engineers from the Chiba Institute of Technology, led by associate professor Shuro Nakajima, have applied a bit of lateral thinking. They have developed a robotic wheelchair that isn't sure what it is. Normally, it operates on wheels like a conventional wheelchair, but when it meets an obstacle, the wheels turn into legs.

3D printed robotic exoskeleton gives young girl a helping hand

3D printed robotic exoskeleton gives young girl a helping hand | Longevity science | Scoop.it

A two year old girl born with arthrogryposis, a congenital disease that left her unable to lift her own arms, although able to walk, has been given a new lease on life by a 3D printed robotic exoskeleton, enabling her to move freely for the very first time.

Partial Hand Function Restored in Quadriplegic Patient

Partial Hand Function Restored in Quadriplegic Patient | Longevity science | Scoop.it

We just saw that a patient was able to control a robotic arm using her thoughts. She was able to give herself a sip of a drink.

 

Now, surgeons at the Washington University School of Medicine have rerouted working nerves in the upper arms of a quadriplegic patient, to restore some of he patient's hand function.

AMES device helps the paralyzed regain movement

AMES device helps the paralyzed regain movement | Longevity science | Scoop.it

Last week, the US Food and Drug Administration granted clearance to a new device that could be of considerable aid to stroke victims or people with partial spinal cord injuries. Created by Dr. Paul Cordo of the Oregon Health & Science University (OHSU) in collaboration with OHSU spinoff company AMES, the "AMES device" reportedly helps the brain get paralyzed muscles moving again.

I think it's wonderful that we're coming up with inventive new ways to help people 'get back to normal'. But stop and consider, perhaps, the validity of a 2,000 year old medicine practice that could provide similar if not better results....at a much lesser cost.

i-Transport robotic vehicle gets wheelchair-bound on their feet

i-Transport robotic vehicle gets wheelchair-bound on their feet | Longevity science | Scoop.it

Constantly being talked down to is bad enough, but wheelchair users also have to deal with the problem of accessing items that are often located out of their reach. A research team from Taiwan’s National Cheng Kung University (NCKU) has developed the “i-Transport” robotic vehicle that is designed to get wheelchair users on their feet so they can carry out conversations eye to eye and grasp hard-to-reach items.

Nose cell transplants allow paralyzed dogs to walk again

Nose cell transplants allow paralyzed dogs to walk again | Longevity science | Scoop.it

Scientists from the University of Cambridge’s Veterinary School, working with colleagues from the UK Medical Research Council’s Regenerative Medicine Centre, have got disabled dogs walking again.

 

More specifically, they’ve used the dogs’ own cells to repair their spinal cord injuries, and at least partially restored the functionality of their back legs. The researchers believe that the process shows promise for use on physically challenged humans.

New hope for people with broken spines: Stem cells bring back feeling for paralysed patients

New hope for people with broken spines: Stem cells bring back feeling for paralysed patients | Longevity science | Scoop.it

For the first time, people with broken spines have recovered feeling in previously paralysed areas after receiving injections of neural stem cells. Three people with paralysis received injections of 20 million neural stem cells directly into the injured region of their spinal cord.

 

The cells, acquired from donated fetal brain tissue, were injected between four and eight months after the injuries happened.The patients also received a temporary course of immunosuppressive drugs to limit rejection of the cells. None of the three felt any sensation below their nipples before the treatment.

 

Six months after therapy, two of them had sensations of touch and heat below their belly button. The third patient has not seen any change. The patients are the first three of 12 who will eventually receive the therapy. The remaining recipients will have less extensive paralysis.

Paralyzed Man Regains Use Of Hands After Having Nerves Rewired | Singularity Hub

Paralyzed Man Regains Use Of Hands After Having Nerves Rewired | Singularity Hub | Longevity science | Scoop.it

A quadriplegic man has regained partial control of his hands after doctors rewired the nerves in his arm.

The 71-year-old patient suffered a spinal cord injury after a car accident four years ago that left him partially paralyzed. Although he was still able to move his arms to a degree, the accident left him unable to pinch or grip with either hand, due to the specific location of his injury.
