Paralyzed Man Walks Again Using Exoskeleton

Posted by kdawson on from the somewhere-there-is-a-crime-happening dept.

dominique_cimafranca notes a story up at the Daily Mail in the UK about a partially paralyzed man who is able to walk again using an exoskeleton frame. The article goes a bit far in comparing the device to Robocop, but it does show pictures of the man, paralyzed for the last 20 years, regaining some use of his legs. Quoting: "The device, called ReWalk, is the brainchild of engineer Amit Goffer, founder of Argo Medical Technologies, a small Israeli high-tech company. Something of a mix between the exoskeleton of a crustacean and the suit worn by Robocop, ReWalk helps paraplegics — people paralyzed below the waist — to stand, walk and climb stairs. The system, which requires crutches to help with balance, consists of motorized leg supports, body sensors and a back pack containing a computerized control box and rechargeable batteries."

    What a fantastic device. I would note that the success of cochlear implants is attributable to the ability of the brain to recognise and interpret any pattern stream. That's why the next device they are working on is the eye. They will not attempt to recreate all the hardware in the eye. Instead, they will look to supply a pattern stream [cue Jeff Hawkins of "On Intelligence" fame] to the brain.

      Well, they've got something like 64 pixels for an artificial retina already, and several research projects are underway to improve this.

      Here is a good list of articles about the University of Southern California Doheny Eye Institute's retinal implants.
      There are also projects based on external cameras, new cameras being developed for artificial retina use, and so on.

      I would note that the success of cochlear implants is attributable to the ability of the brain to recognise and interpret any pattern stream.

      Actually, this is a bit misleading. Cochlear implants break the sound up into different frequencies using a fast fourier transform, and sending signals based on the various frequencies to the appropriate nerves. While the cochlea doesn't do math, obviously, the hairs of the cochlea perform more or less the same function with different hairs resonating at different frequencies and depending on which hairs resonate, the appropriate nerves are stimulated.

      So really, a cochlear implant performs virtually the same function as the cochlea sending pretty much the same patterns to the brain.

      I agree that the brain is very flexible, but if a cochlear implant didn't provide virtually the same signal that the cohclea does, the people using them would have to learn to recognize speech and other sounds from scratch, which isn't the case. This is why people who have lost their hearing for only a short period of time tend to find them more useful than people who have been deaf for life.

      The brain is quite adaptive, but to say it can "recognize and interpret any pattern stream" is a great exaggeration. Additionally, most of the brains adaptability comes at an early age. By the early 20s after most of the synaptic pruning has happened (young children have roughly 10 times as many synapses as adults), the ability of the brain to learn new things, particularly the generalized pattern recognition type abilities, becomes greatly diminished.

      So obviously you haven't heard of the experiment where they created a device with a grid pattern of dull pins. The pins formed a grid pattern that was placed on the tongue. When the pins were raised in the manner of a object that was seen by a video device, the wearer could learn to interpret the pattern of raised pins just as if they had seen the pattern coming in from the eye. In the experiement, wearers could learn to see obstacles and avoid them in walking and also to "see" things like a drinking glass and reach out and grab it. So, I stand by my statement. We have yet to reach the limit of the various patterns a brain can interpret.

      Because it's difficult? The Segway doesn't just balance by code, it's a product of having two big, grippy wheels with heavy-duty motors listening to a whole bunch of clever hardware to track the centre of gravity. All that to balance a vehicle which is basically a really heavy board on wheels with a stick out the top. This exoskeleton is an order of magnitude more complex, and no doubt has nowhere near as much torque or traction available to it.

  17. Hard to do in real life by DrYak · · Score: 3, Interesting

    Even if the exo-skeletton is made to walk, it won't be suitable for all paraplegic patient.

    There's a major problem with this kind of device : the patient is staying upright. And thus is experiencing decreased blood pressure in the upper part of the body and increased pressure in the lower part.

    For a normal person in good health this isn't a problem, because when upright, we have mechanisms to compensate for the hydrostatic pressure.
    The problem with paraplegic patient is that the nervous pathways controlling this might be broken. Muscle contraction also play a role to keep the blood-pressure and, well, those don't work in a paraplegic patient.

    Probably a significant propotion of the patients will need to where special undergarment (like grandmas with venous problems and like some surgeon do) or trousers (like pilot's G-suits) to avoid passing out whenever in upright position for prolonged time.
