ARGO Medical Technologies' ReWalk has been out a few months now, but it's tough to really appreciate what this thing can do unless you see a patient utilize one on video. Hailed as a "quasi-robotic ambulation system," the wearable device was specifically created to assist those with lower-limb disabilities and give them back upright mobility. In the video waiting in the read link, one particular individual relies on the ReWalk to stand up and move about after being stricken to a wheelchair for 20 years -- no need to take our word for it, though, real live proof is but a click away.

Brain-machine interfaces have done quite a bit in helping handicapped individuals interact with prosthetic limbs, computers and other humans, but a new neural implant concocted at the University of Florida could make all those past devices look archaic. Put simply, researchers have discovered a method that would enable brain-machine interfaces to "adapt to a person's behavior over time and use the knowledge to help complete a task more efficiently." Until now, the brain was the instrument doing all the talking while the computer simply accepted commands; with this method, "the computer could have a say in that conversation, too." In all seriousness, this type of learning mechanism could be game-changing in the world of physical therapy, but we hesitate to give something mechanical inside of our body too much free will, ya dig?

Here's your heartwarming story for the day. Microsoft has teamed up with Companions in Courage in order to bring "hundreds" of Xbox 360 kiosks to children's hospitals across the nation, and the gaming stations have already been installed at Morgan Stanley Children's Hospital of New York-Presbyterian, Children's Hospital & Regional Medical Center of Seattle and the Children's Hospital of Orange County, California. The customized units are "hospital-friendly" and come pre-loaded with a variety of E and E10+ rated games, Y-rated television programs, G-rated movies and the Xbox Live headset / Vision camera in order for gamers to play online. Speaking of, each kiosk is wired to a private Live network which "allows hospitalized children across the country to play games and chat" with each other. There's no word on where the stations are slated to arrive outside of the three venues already mentioned, but those interested in broadening the reach of the endeavor can feel free to donate to the cause.

Sure, we've seen brain power used to give mobility back to the immobile, but a new development in Europe is one-upping current efforts by adding in a hint of artificial intelligence to the tried and true brain-computer interface. The MAIA BCI not only converts signals emitted by the brain into actions -- such moving a wheelchair forward -- it also thinks for itself when needed in order to assist the user in getting where he / she wants to go. Essentially, the individual need only think about going left or forward (for example), and the machine itself will automatically detect obstacles and potential barriers in order to move more efficiently. As it stands, there's still quite a bit of testing to be done before MAIA-based wheelchairs would be available to the public, but researchers are already hoping to integrate said technology into artificial limbs and the like.

Yeah, we've got HMDs for the visually impaired, but seriously, who's for sporting one of those things just to catch an afternoon soap? Thankfully, Dr. Eli Peli (and colleagues) from Harvard Medical School is lookin' out for said sect, and has developed a method for "enhancing the contrast of images of people and objects of interest on their digital televisions," which, during trials, was found to enhance legibility and overall enjoyment when watching. Furthermore, the technology is said to be the first to play nice with digital TV images, which seems fairly important considering that analog signals have but a few months to live here in America. Purportedly, the all-important modification that made the adjustments possible could be applied to HDTVs and digital STBs in the future, and sure enough, Peli has already sparked up conversation with Analog Devices in order to create a prototype chip for use in forthcoming sets. Now, if only clearing up those Get Smart reruns were this simple...

Thought-controlled appendages are far from new, but an international team of researchers have apparently created an apparatus that aims to make the lives of paralyzed individuals a tad easier. The Brain2Robot project utilizes electroencephalograph (EEG) signals in order to give patients the ability to control a robotic arm, which could eventually be used to do everything from hold periodicals to lift a cup of coffee. Reportedly, the arm could be ready for commercial use within just a few years, but there's no mention of an expected price range. Granted, we'd be a bit more excited about all of this if the technology were somehow made mobile, but it's hard to kvetch about a helping hand, regardless.

If you're suddenly overcome with an eerie feeling of déjà vu, fret not, as this idea has certainly been brainstormed before. As scientists aim to make prosthetic limbs more user-friendly, a certain physiatrist at the Rehabilitation Institute of Chicago and professor at Northwestern University has developed a technique that enables artificial arms to react directly to the brain's thoughts. The process, dubbed targeted muscle reinnervation (TMR), works by rewiring residual nerves that once carried information to the now-lost appendage to the chest; when the person thinks to move their arm, the chest muscle contracts, and with the help of an electromyogram (EMG), the signal is "directed to a microprocessor in the artificial arm which decodes the data and tells the arm what to do." Currently, "only" four movements are possible after the procedure, but studies are already in full swing to determine if TMR could be used to bless future patients with an even fuller of range of motion.

There's a multitude of options out there for handicapped individuals who want to surf the 'net, but a team at the University of Washington is adding one more by developing software that can convert one's voice into cursor commands. Notably, the Vocal Joystick doesn't rely on any speech recognition technology; instead, it "detects [vowel] sounds 100 times a second and instantaneously turns that sound into movement on the screen." Users are then able to move the mouse around the screen and click on links by simply making a variety of noises, and the cursor even speeds up as the person increases his / her volume. 'Course, we're not exactly sure how text is inputted into the address bar, so you'd better have your favorites fully stocked before relying solely on this.

It's been quite a while since we've heard anything new on the C-Leg, but German firm Otto Bock has now unveiled a sleeker, stronger, and more military-approved version for those in need of a new leg. The microprocessor-controlled knee joint is "the standard prosthesis issued to US fighters who have lost a leg above the knee," offers up a number of "modes" to best suit your current activity, and includes a wireless remote for switching between those modes. The intelligent system within takes data samples of your gait 50 times per second in order to best adapt to your needs, and the internal hydraulics promise "optimal response" no matter how strenuous or demanding the chore. Of course, buying a leg that seemingly puts these natural ones to shame won't run you cheap, as the newest C-Leg will reportedly cost somewhere in the $30,000 to $40,000 range to have it delivered and fitted.

We've seen a smorgasbord of off the wall creations designed to help those with limited motor skills interact with the average PC, but a group of Kent State researchers have returned to square one and devised a more useful method of actually getting the computer turned on in the first place. The team, which including a graduate assistant who has quadriplegia, found the solution by "adding a jack to the back interior wall of the tower and paralleling it to the on / off circuit of the motherboard." Subsequently, any number of sip / puff switches (pictured device is for reference) could be attached to the jack in order to power the machine on without the use of one's hands or feet. Sadly, there was no mention of bringing such a useful creation to market, but with the right handyman, we're sure this project wouldn't be too hard to replicate on your own.

Early last year, gurus at the University of Michigan were devising a newfangled type of cochlear implant, but now it looks like the Wolverines are more interested in a fresh auditory nerve implant that is being dubbed "a superior alternative" to the (now) old fashioned option. The uber-thin electrode array would purportedly "transmit a wide range of sounds to the brain," and could give profoundly and severely deaf people the ability to "to hear low-pitched sounds common in speech, converse in a noisy room, identify high and low voices, and appreciate music." Researchers on the project are convinced that this technology trumps cochlear implants in every way, and while preliminary patents have already been filed, it'll still be nearly a decade at best before these things can invade human ears en masse.

Nah, it's not quite a throwback to the 80s, but Zane Van Dusen has co-developed "a computer interface that tracks the movement of a user's head to allow them to produce electronic sounds and compose music on a virtual keyboard in both solo and ensemble settings." The Rensselaer Polytechnic Institute senior worked with a team of musicians and programming gurus to create a device that would enable those with extremely limited mobility to still express their creativity through music, and aside the from therapeutic benefits, it also holds promise for expanding into a venue for verbal communication. Essentially, the user can line him or herself up with a camera, and as the head bobs, the software determines the new X and Y coordinates and "uses the information to play a note or trigger a sound." While it might not be quite as totally radical as the Guitar Zeros, it sure sounds more exciting than the Bacterial Orchestra.

Although we've seen gait monitors and even prosthetic feet that assist individuals in regaining a more natural stride, scientists at Technion Institute of Technology in Israel have resorted to a head-mounted display for its rendition. This virtual reality device combines "auditory and visual feedback to improve walking speed and stride length in patients suffering from Multiple Sclerosis and Parkinson's disease," and provides the wearer with a "tiled-floor image" that apparently assists them in navigating nearly any terrain. The device is meant to take the place of normal muscle feedback mechanisms, and to provide said feedback to these disabled individuals so they can make adjustments and improve the efficiency of their walk. The HMD has already made its way to several medical centers and has purportedly yielded positive results, but there was no word on when this device would be commercially available.

After a solid four-mile run on the Doggy Treadmill, it's not too tough to understand why Fido is famished, but for folks who are disabled in ways that make bending down or moving around in general difficult, getting the pet food from the pantry to the bowl has been a serious chore. Thanks to a retired engineer (who was stricken by cerebral palsy) that figured he better solve his own problem rather than wait for someone else, the DinnerUp apparatus was concocted, and now it's on the brink of commercialization. The device mounts onto a kitchen counter or door and relies on a hand crank / clutching system in order to lift the attached bowls to a level that's easy to reach, after which it's lowered back down to the anxious pets below. Currently, Ray Dinham is assembling the units himself and offloading them to "satisfied customers" for £70 ($140) apiece, but it shouldn't be long before the manufacturing is "outsourced to a UK-based firm" and these gain some serious worldwide traction.

In an attempt to create a more fashionable alternative to the wheelchair devices that handicapped children currently rely on to get around, a group of engineers at the Bath Institute for Medical Engineering, in consultation with parents and occupational therapists, have concocted the car-like Whizzybug. The all-terrain vehicle can reportedly handle asphalt and green pastures without issue, and sports a blistering top speed of two miles-per-hour. Additionally, it can be controlled by the caregiver or the youngster, weighs in at just under 70-pounds, has a "fully adjustable seating system with memory foam cushions and a programmable joystick," and to top things off, this bad boy even touts a trailer hitch for towing those weak Power Wheels rigs out of the rough. The devices are slated to be sold by the developing charity, Whizz-Kidz, "at cost," which means that interested parents will be looking at anywhere between £1,700 ($3,406) and £2,000 ($4,007) depending on options.
