Unpowered ankle exoskeleton takes a load off calf muscles to improve walking efficiency

By - April 1, 2015 4 Pictures
We might have started off in the water, but humans have evolved to be extremely efficient walkers, with a walk in the park being, well, a walk in the park. Human locomotion is so efficient that many wondered whether it was possible to reduce the energy cost of walking without the use of an external energy source. Now researchers at Carnegie Mellon and North Carolina State have provided an answer in the affirmative with the development of an unpowered ankle exoskeleton. Read More

Swaying this way saves energy while walking

Just two days after opening, The London Millennium Footbridge was closed to eliminate its sway. Turns out staying with the sway would have had its benefits, as researchers have found that it reduces the amount of energy expended when walking across the bridge. Read More

Spinal implant could one day let paralyzed people walk again

By - January 9, 2015 3 Pictures
Three years ago, scientists at the Swiss Federal Institute of Technology (EPFL) reported success in getting rats with severed spinal cords to walk again. They did so by suspending the animals in a harness, then using implants to electrically stimulate neurons in their lower spinal cord. Although this ultimately resulted in the rats being able to run on their previously-paralyzed hind legs, the technology still wasn't practical for long-term use in humans. Thanks to new research conducted at EPFL, however, that may no longer be the case. Read More

New robotic walker helps patients walk with a natural gait

By - November 26, 2014 1 Picture
It can be a laborious business, teaching people such as victims of strokes or brain injuries to walk again. Often, multiple physiotherapists are required to hold patients up while they walk on a treadmill, while also manually moving their legs to achieve the proper gait. Soon, however, a robotic walker developed at the National University of Singapore could make the process considerably easier. Read More

Vibrating insoles could help prevent falls among seniors

By - October 31, 2014 1 Picture
Falls are the leading cause of death by injury amongst seniors, and those falls are in turn typically caused by poor balance or an irregular gait. Taking things back yet another step, problems with balance and gait are often caused by diminished sensation in the feet. Now, however, a new study indicates that subtly-buzzing insoles may help seniors regain some of that lost sensation, and thus be less likely to fall down. Read More

Brain-controlled exoskeleton to help kick off FIFA 2014 World Cup

By - June 11, 2014 6 Pictures
On June 12th, the FIFA 2014 World Cup in Brazil will be kicked off by a paralyzed person using a highly innovative brain-controlled robotic exoskeleton. This feat is being carried out as a demonstration of the current state-of-the art in assisted mobility technology, as the researchers involved – part of the "Walk Again Project" – work toward refining their invention.

Human stem cell treatment gets mice with MS-like condition walking again

By - May 28, 2014 1 Picture
When scientists at the University of Utah injected human stem cells into mice disabled by a condition similar to multiple sclerosis, they expected the cells to be rejected by the animals' bodies. It turned out that the cells were indeed rejected, but not before they got the mice walking again. The unexpected finding could have major implications for human MS sufferers. Read More
