The Cybathlon 2020 race rules confront us with two interesting Catch-22 aspects:

-hammering (if not other dangerous) activity that is not endorsed by "bionic" hand manufacturers

-use of damaged / perforated covers, not endorsed by Ossur [link]

A hammer, particularly a cheap or small one, even more so than a heavy dangerous "real" hammer, is an unlikely tool to use with an ~80 000 USD myoelectric "bionic" device that is specifically built to sustain only the lightest of work. And the subject of hammering, technically, as arm amputee with a prosthetic arm, has become relevant since the Cybathlon 2020 directors [link] have taken it upon themselves to make it a "discipline".

STOP - HAMMER TIME?

"With that, visitors of the Cybathlon Experience (TM) can test the role of a disabled person" (können in die Rolle einer behinderten Person schlüpfen) (Oral presentation: "CYBATHLON – bewegt Mensch und Technik", 5.15pm–6.00pm, Dr. Roland Sigrist, Cybathlon, ETH Zurich, Raum E 1.2) -- I was there, one among the 8 people that made the audience of this "sold out" Cybathlon talk; amputees are there for "entertainment" (clearly one of the requirements written on a slide in the presentation) (ist es das, was wir als behinderte Personen spielen? eine Rolle, ja?).

After defining a remarkably strange prosthetic arm race, the makers of the Cybathlon 2020 now start to openly bathe us in their pitch-black cynicism.

Why? Pressing question.

Modifying Shimano Ultegra road bike setup on a Colnago C40 for left handed use - second approach [technical right below elbow amputee core focus work / bike adaptation]

After a first approach, where also the history and idea where it came from is detailed [link], I now set up and tested a second approach to modifying my Colnago C40 carbon bike with a triple chainring Shimano Ultegra chainset.

The extensive testing of my first approach that I had performed there lead to a range of concise detailed issues and problems. There were now addressed, all, and thus a second (and significantly better) approach resulted.

As stated before, no disability sports advocate specializing in road bikes and no bicycle mechanic specializing in individualization and custom solutions over the years ever thought this was possible in this way. They all said it could not be done. And I had asked a few of them, since it had bugged me a lot. And as I had sold my Cannondale road bike after the amputation, thinking there was no way, I now got myself a road bike back and decided to go down my own path to really use it the way it is meant to be used.

Generally and as part of riding a road bike, I wanted fast and comfortable gear switching, fast and accessible and comfortable braking, and I wanted to be able to enjoy various and if possible equally comfortable sitting positions or body positions. A great road bike trip may be a lot longer than a fast mountain bike trip into the forest. Last but not the least, as amputee my stump usually would suffer from vibration induced pain after 20 minutes  particularly with hard connectors such as the Mert or Freelock adapters, so padding definitely was an issue.

Ich weiss jetzt nicht, ob Sie das mitbekommen haben. Und ob Sie begreifen was da passiert ist.

Aber am Cybathlon 2016 (Cybathlon, ETH, NCCR Robotics), einer Art Behindertenschaulaufen ohne besonderen  wissenschaftlichen aber dafuer sehr publikumswirksamen Hintergrund [wieso/was:link] mit mehrheitlich durch das Patronat der ETH suggerierten "High-Tech-Hintergrund" gewann ein Mann das Armprothesenrennen, der einen "Hook" trug [siehe detaillierte Griffanalyse, link]. Arschcool, mit 67 ein Senior, dort auch klar der älteste.

Fehlerfrei und schnell.

Executive summary

  • Arm amputation is more a social (and complex) than just a manual handicap in many daily situations. Therefore many approaches to dealing with it are social and socially motivated, including hand color. You did land on a right below elbow amputation website, like, apparently, so that is the angle from which this comes. Also we made sure this is the title of this website. Different aspects may apply to higher level and bilateral arm amputation, but that is not the target of this website.
  • Conversely, most actually manual problems are not major. What heavily impacts many unilateral arm amputees after 5-8 years or maybe after 10 -20 years, is the impact of overuse of the intact arm and asymmetry related problems. A rational approach to prevent that is to use prosthetic arms that excel particularly at the heavy to extreme range of physical exposure. Those are typically modern body powered arms. These use well established control principles, but can be made from very modern materials. They suffer from medial representations that are largely negative ("Captain Hook"). Myoelectric arms are termed "high tech" simply because they may contain a battery and motors, but they suffer from a battery of intractable or constrained problem combinations.
  • For that, the ETH has so far not been necessary to add to the field of prosthetic arms, but trash culture approaches have a lot going for them regardless of that. My own practical and pragmatic research (see also below) contains such elements and now, the ETH also is proud organizer of a Circus freak show (which in essence is an event that lacks academic approaches and reduces intellectual participation to staring).
  • Neither the ETH nor the NCCR Robotics ever managed to acknowledge that or develop even the tiniest solution to solve just about anything in that matter (remember the title of this page?). That is perfectly OK as quite possibly, myoelectric arms are uninteresting from an actual researcher point of view once one understands the full scope of problems, and body powered arms are uninteresting because their problems are a combination of mechanics, material science, and context dependent issues that usually require deep insights which is currently performed by a small relatively close knit international community of amputees, developers and researchers.
  • Given their academic background claims, ETH or NCCR based approaches could and should have focused on studying intricate differences and aspects of prosthetic arm success and failure during the Cybathlon competition in all situations, pre-race and in-race. I mean: if you claim you want to do, or push, research, better sit down and work on a really detailed introductory explanation to show that we all see how much you understand what detailed features we are all looking for. I am most definitely all for that, but I do not shy away from weird staring contest evaluations either. These define an amputee's daily reality more than you might like.
  • But to no surprise, the technical research representatives neither prepared, nor carried out, such, so any technical analysis of the race that then was presented to the public to actually increase some real understanding for the effectively present research problems and real world issues so it will never be possible in sufficient detail or write any great scientific paper about it. Or, not from how it looks now.
  • Thus, academically (not industrially, not as bystander, person that loves to stare at arm amputees or spectator), the event of the Cybathlon prosthetic arm race was a thoroughly missed opportunity if not a failure.
  • This does not mean that the Cybathlon as such was meaningless; it just showed that body powered technology (TRS, TRS prehensor) as very calmly and perfectly performed and carried out by a 67 year old man (Bob Radocy) that did not visibly hurry but chewed gum for the whole event left all "robotic" competition behind - while I had warned the organizers from a one-dimensional overly simplistic evaluation two years ago. I had always told them exactly what Claudia Breidbach said in her statement after the finals race: you cannot compare, across various different arm amputation with adapted different devices, what a good performance is. They knew as they had been extensively informed beforehand. The search for what prosthetic arms should be able to actually do well remains ongoing though, the odyssey apparently continues with a Cybathlon 2020.
  • And while any evidence based rational mind would now more than ever (a) want a body powered prosthesis and (b) further research on that type of prosthesis, it was the very clear aim by the organizers to not include these arms in the race at all, until I had imposed myself onto the organizers, had a very serious word with them and convinced them to admit also body powered arms which they did.
  • The Swiss National Foundation (SNF) is strongly advised to look into the intricate aspects of all failures of (a) research opportunities missed and (b) strategic solutions actually needed in prosthetic arm and hand field, (c) appoint very competent coordinators and advisors there and (d) not finance silly "competitions" such as this that do not further science at all or (e) finance more myoelectric nonsense.
  • All the same, the Cybathlon was a great experience in how ETH hype, tech media hype and gadget hand industry hype take a royal tanking against real life based real men, and, if you need a short but intensive read on the reasons why the myoelectric arms missed out today, check my Cybathlon Symposium scientific contribution, you will find there more relevant text than in many other places.
  • I do not hate myoelectric arms. Personally I must have invested more finances into my own myoelectric gadgets than into my body powered components. However, that does not make me blind, dumb or gadget happy. I still test, look, think and analyze. I still work on finding better ways, solutions, parts or usage tricks for both systems. But then, coming from an engineering perspective (funny you come here to read that) - finding the exact problem, identifying the exact issue, has been placed before being ablt to solving it. And the simple beauty of engineering is, that whatever your attempt at covering up your tricks, at the end of the day, the contraption either works, or it does not.
  • While Professor Riener verbally once (1) at the Cybathlon race itself mentioned the fact that cable powered technology won (we were there, see Gonzo report below), they made sure none of that leaked to the Swiss television, or BBC, or newspapers, or IEEE, or other press. They simply buried the fact that they were left eating dust by some very athletic older gentleman wearing a body powered prosthetic arm. Because that is like having someone in sandals and swim trunks run up on Mount Everest. They do not report that as it is seen as putting the other efforts to shame rather than being seen as someone, something, a situation to finally learn from. And that puts massive question marks to the news writers, tech representatives and researchers: is what you do something we have to believe, because quite clearly, facts are not consistent with it? Do you represent a type of religion or belief system?
  • Not all are like that. The Scientific American, a journal that I am a subscriber and reader of since many, many years, reports extremely well, and explains the actual technical aspects of the winning device.
  • The Cybathlon was announced as competition that allows visitors to "understand the issues surrounding disability in a practical way". When not even the organizers understand these issues, and not even in a theoretical way, how on earth can they assume an ability to instruct visitors so they understand disability issues?

Trash Culture, the Cybathlon prosthetic arms race show Circus, and other prosthetic limb Trash Culture approaches

"Mommy, do I have to repeat every mistake others made before me myself?" - "Yes, one can learn so much from mistakes".

Don't get me wrong here.

Trash Culture is a great contemporary experience. If anything, this is what gets people talking. But it is not research or academic. This is not at all a critique, but an attempt to better localize this strange event in context of prosthetic arms, amputation and society.

It is just a Circus.

To unmake it a Circus and Make It a Technical Contest, a bit more attention to detail would have be needed. A lot more attention to detail would have made it a great event. That all was missed.

Now, I will supplement you with the required extra details below to make it a research observation despite the organizers successful attempts to keep it simple, hip, sexy and trashy .... but let that not spoil the fun for you.

New visibility for very old symbols? Viktoria Modesta, Prototype, Channel 4, "spike dance" [media review]

Viktoria Modesta, Prototype, Channel 4, "spike dance" [media review]}}, month = {December},year = {2014}, url = {https://www.swisswuff.ch/tech/?p=3883}}


From [link]:

According to Viktoria Modesta, [link], the new video has given her the chance to express some of her more extreme ideas and continue in her fight against being categorized. Along with the video's director, Saam Farahmand, Modesta achieved these aims with the help of Sophie de Oliveira Barata at The Alternative Limb Project – a fascinating venture which creates bespoke, often highly artistic, prosthetic limbs for clients. In the 'making of' film, de Oliveira Barata explains how she created two bespoke limbs for Modesta – one that lights up and has an exposed mechanism (see above), and another that is essentially an elegant spike which Modesta equates to a kind of power dressing. The latter design appears towards the end of the Prototype film in a sequence that brilliantly combines dance, colour and sound design to dramatic effect. "For a long time, pop culture closed its doors on me as an amputee and alternative artist," Modesta explains. "I think people have always found it hard to know what to think or feel about an amputee who wasn't trying to be an Olympian."

Essentially, she is still in the process of counter-reacting to feeling as a victim of society and poor ability, leg wise. The spike does transform her into "something" else. It gives her "special powers". Also, there needed to be a deliberate collision between that "reality" and the one with the surgically cut off leg, as the director says in the "Making Of". Viktoria Modesta says that she tries to "bring some equality" into "the equation". Later the director admits that what she really is trying to do "is the big question". Apparently, she is publicly exploring "the fullest, richest version of herself". Modesta says that she is not considered to have a body that "is healthy in any terms". The director states that the video "is naughty" "because" Victoria "is a naughty person".

Moving on, I found that I really want a 'hand looking something'. Just because I like its shape look so much better than any other things there. Call me an anthropomorphophiliac.

I still feel significantly quieter, safer, relaxed and self sufficient wearing the hook whereas the hand is not giving me that feeling of being able to rely - but the shape of the hand itself is dear to me, it has a nice to look at aspect.

As other people definitely stare no matter what, I found out that wearing Red (instead of skin colored attempts) appears to shift responses from stressful childish or confused responses to far more mature or matured ones. Obviously we are dealing with each other in terms of "what type of person are you" before we deal with each other in terms of "who as an individual are you".

So in case you want to see the past and future rest of this project, click on the link to my Red Hand Series.

I am significantly inspired by designers' attempts to be 'proaesthetic' (Hans Alexander Huseklepp) or to 'translate an arm into a prosthetic arm' (Marek Gut). Current prosthetics generally lack humanity, style and grace. Often, current prostheses look much like landing gear and make the wearer uncomfortable, self aware, and sometimes depressed (Johanna M. Hawley).

There are certain hard minimal requirements - a prosthesis must be fully reliable, it must be stable and solid up to a point, and the socket or stump mount should be really comfortable and it must not hurt. But other than that, we are free in choosing material and appearance.
