Climbing 103 Floors On a 'Bionic' Leg 117

An anonymous reader writes "4 years ago I read about experimental targeted muscle reinnervation (TMR) surgery on Slashdot. 3 years ago I crashed my motorcycle and had my leg amputated — at which time I had TMR done. Today I climbed 103 floors of the Willis Tower in Chicago with a experimental prosthetic using TMR. Thanks, Slashdot."

    Congrats!

    Out of curiosity if you don't mind the (potentially awkward) question, how does it work/feel when you control a bionic leg? Scanning the wiki article, I sounds like it's basically plugged into the nervous system at where the amputation took place, and you had to retrain the neural system so the bionic limb responds accurately? (Complete with some level of sensory feedback?)

    • I've always wondered about that too. I guess there isn't much sensory feedback other than yourself seeing your bionic limb movements, which might well be enough. I don't know if you can actually feel your foot touch the ground or anything.
      • My guess would be that you would feel the pressure at the point where the artificial limb is attached to the body when you shift your weight to that side.

        Also, huge props for not giving up to the OP.

        Now, I would be curious to know if medical paid for it, or if he paid out of pocket (or with donors helping out).

      I don't know about a bionic leg, but I have a bionic lens in my left eye. I had to practice reading to strengthen the focusing muscles I hadn't used in ten years, but the actual workings are just like with a normal 20 year old eye. even though I'm 60..

          The choice of surgeon REALLY matters. I was severely nearsighted all my life, and farsighted as well in my forties. The eye with the implant is better than 20/20 now, stats say something like 98% of patients who get that lens have 20/25 or b

        I have a friend who claims (or rather his opthamologist claims) that the problem with these lenses is that your eye muscles are not strong enough to focus them properly after age 50 or so. That does not sound like your experience, so I am wondering how you did it?

    Wondering if the data collected from this cyborg (yes dude you're now a cyborg), could also be useful as training data for independent robotics.

    Have you ever thought of open sourcing your leg data :) Could be a huge contribution to OSS robotics. Maybe get other's with prosthetics to contribute as well; arm, hands, feet.

    • As awesome as that would be.. I'm betting that the company that made the leg owns the rights to all the data generated from it.

        Retarded kids are sub-human and don't need rights.

        In my state, the same laws that make it illegal to fuck 12 year olds make it illegal to fuck retards. Every time wording is encountered about someone being too young, it involves a list of things separated by commas. Under X age, or with more than a 4 year age difference, or with reduced mental facilities. They go through every length to make sure screwing retards is the same as screwing very small, possibly pre-pubescent children.

        • Retards must be removed from the gene pool because they have less functional brains and are thus less human. Making it illegal to screw sub-human retards is the best way to do that, according to my state politicians. I see now. "Protecting them" is a good cover story.

          Umm....it's about ability to consent. To the best of our knowledge and ability, people who are protected under such laws lack sufficient faculties to grant consent to the person having sex with them. Ergo, they were raped. It has nothing to do with "purifying" the gene pool, and everything to do with being as humane as possible to people who got a raw deal due to fate/circumstance/birth/whatever.

          • Yes, exactly. So while 19 year olds can have premarital sex in college with their entire dorm and come home pregnant, retards are just like the 12 year old gifted girl that made it into college early by passing her GED and escaping middle school: oh she's a hot college freshman, but if you fuck her you go to jail.

            You see? This is how we ensure 'humane' treatment and 'protect' these people. Make sure nobody can 'take advantage of them'. If they get pregnant, somebody done broke the law.

          As the father of an educationally handicapped adult daughter I find your attitude highly offensive. Most mental handicaps are not hereditary; my youngest daughter has an IQ of 130. The oldest was born with the umbilical cord wrapped around her neck, had it not been for that her IQ may have been higher than her sister's.

          Take your argument a little farther, we shouldn't let anyone with less than a 150 IQ live. E.g, I live, you die. Compared to me, you're a retard. Compared to Stephen Hawking, I'm a retard.

    I'm curious as to how the neural interface works. The CNN article was pretty vague (saying something like "He thinks it and it moves"). I imagine there is a lot more to it than that. Most interfaces I've seen in the past that called themselves a "neural interface" were actually just glorified physical interfaces (controlled by twitching muscles in the upper limb or something like that). Is this thing actually connected to his brain, or at least to his nervous system?

      The idea here is that you take all the nerves that would go to the amputated limb, and reroute them to some other muscle group. Then you hook your sensors up to the new muscle group and move the limb based on how that muscle twitches. But, since the nerves have been rewired, you don't have to think about twitching your thigh to move your calf, you just try to move your calf and the prosthetic responds intuitively.

    • The great thing about it is that there is no direct neural interface with electrodes in the muscle. Because anything foreign in the body tends to be corroded over time by the immune system. Dr. Kuiken gave a presentation on his technique at last years CHF festival in Chicago. The idea is for the nerves to fire and to be detected by sensors placed on the skin on order to move. I expect the good doc to perfect a "Hechatonchires" full body prothesis any decade now. Appleseed, here we come.

    • What I want to know is how is this powered. Not by raw muscle movement pulling cables I guess. Lithium ion (4 hole chemistry)? Organo-lithide high-capacity (6 hole chemistry) batteries? Beta-voltaic cells with a small piece of radioactive material (20 year battery)?
