João sem braço ("armless John") is a Brazilian or Portuguese idiom that is used as an epithet for an ignorant and lazy person.

As that in itself is hardly a positive attribute, it is relevant to understand the position of amputees in society, their individual and collective role, in order to see how this is a very ableist and thus derogatory way to formulate the attribute of ignorant or lazy.

BLUE LIGHT SPECIAL - defect iLimb glove poses tricky Catch-22 for Cybathlon 2020 [review]

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 [link]

-use of damaged / perforated covers, not endorsed by Ossur (see here)

The iLimb user / clinician manual clearly states "do not use without an approved cover", "do not use with a damaged cover", and, "damaged covers must be replaced by a qualified Touch Bionics technician or technical partner" 1.

However, the Cybathlon Karlsruhe 2019 footage clearly exhibits a torn and perforated glove (defect over the knuckle of finger II/index finger) being used during the competition during the task that has the competitor push a card into a slot.

From view of a user that had serious issues with these "glove covers" that Touch Bionics (then) / Ossur (now) sold for a premium, and who knows a lot about replacing these with better parts despite manual regulations, this is VERY interesting: because a damaged cover unnegotiably operates far outside the acceptable use condition that appears to be insurable. And insurance seems to be a thing there.

To remind you: Touch Bionics glove covers die by themselves when left alone [link] or when used for something as minor, uninteresting and light as a 10 minute car wash [link]. I was left to myself to identify a work glove [link] and a durable cosmetic glove [link].

-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".

A full understanding what amputees do or do not in their real life has so far escaped the acumen of research and development. This explains how > 85% of us still run free, without the real restriction of having to pay massive money for technology that basically makes life more difficult.

A notable exception is my body powered split hook. As we can show how academics comprehensively fail to grasp (haha) the scope and use of prosthetic arm use, even a modest achievement such as this appears quite noteworthy and definitely reportable. After all, absolutely no (0) achievement was delivered by any R&D in the domain of myoelectric arms to this day that has made it to actual everyday use and hard work delivery, both since Cybathlon 2016 (that promised it would "push" development) and generally since >40 years of "research" into myoelectric arm control. As they all have more than a lot to learn (not advancing problematically high error rates in >40 years is a catastrophe or wouldn't you say), we are called upon to focus on the basic.

Myoelectric prosthetic arms do not "really" work, we all know that, and it has been clear for decades.These factual aspects are difficult to make that problem go away like, poof. With that the more interesting question is: whom do we sell these to?

While selling to people that are gullible [link] seems to have a lot going for it, it is risky. A more sustained approach may base on taking actual risk factors for myoelectric failure into account:

  • Sweat
  • Weight

User perspective on the rubber hand illusion in a wider sense – prosthetic arm and ownership for real use [reflection and consideration]

The year 2018 was interesting in relation to the rubber hand illusion subject.

I had participated in an extensive interview study regarding embodiment just a year before [link]. Then, I had been identified as a prosthesis "super user" [link] - these people wanted to investigate my type of "embodiment" through fMRI, but we quickly identified my prosthetic arm design (not my brain) as the key aspect regarding the question of why I have a prosthesis that I can actually use rather than just pose with as so many others. My own view here clearly is that if you are after embodiment, you have to go all Sherlock Holmes, you have to go all forensic, all CSI and all crime mystery: and as in "cherchez la femme" when looking for a motive in a crime, it is "cherchez le bras" when studying embodiment: for all issues that center around prosthetic use, go for the core physical aspects first. There are extremely bad things that may, can, and will happen if you do not make that your real first priority. The "rubber hand illusion" is an extreme variation of body ownership of a rubber hand that does not even touch a person and still that person thinks they are being touched if that rubber hand is touched. The illusion to make an amputee believe they embody or bodily own a prosthetic hand is quite different. But both pose risks, whereas the risk that an amputee faces when getting a prosthetic arm that is integrated into his body image has not been considered yet. My slightly experience based consideration proposes that the body image is tyrannically governed, for good and for bad, and if the prosthetic body part - already starting with bad cards, body image wise - craps out, and it always does so far too often, then it draws the hot red angry ire, the depressed disappointment, the falling apart of the cyborg body, of the amputee - and definitely not the cool "oh a neutral object just disintegrated" that one will wish for from a societal, insurance or repair view. The integration into a body image brings with it that the device becomes subject to totally tyranically governed bodies. When it is difficult enough to make any device ready for real world usage, making it ready to survive tyrannies of that nature will be even harder. I proposed an unforgiving approach to failure testing in a recent paper (link) but I cannot say that paper has been greeted with any enthusiasm by the industry that actually builds prosthetic arm components. Because they get to directly face the anger, hate, and rejection of all the users that they had not informed well of just how fragile their prosthetic arm parts really are (link), and they are in absolutely no position to technically improve these parts. So, manufacturers go into hiding. They do not want many users - they want users that buy and do not complain. The last thing they need is a hard bright unforgiving look into just how bad their engineering is. Every non-user, every rejector, should be cautiously left alone, not recruited to wear a prosthesis - because the risk is considerable (link). Researchers currently have the problem that amputees run away, everywhere (link), also because we are continously treated as mentally incompetent. So in essence, we are a group of people that increasingly realizes the extent to which we are being fooled, being had, told stories, and increasingly, we are getting critical. Potential rubber hand illusion switches, dragged to market to be soldered into prosthetic arms, if ever they are a medical treatment or a part thereof, will have negative effects as well: what are these? What do we know about deeply problematic aspects of bodily ownership? I had been invited to talk about that aspect for a group of people interested in robotic control and user interfaces, on December 7th 2018, in Mannheim (Germany). The presentation that I gave now is typed out here in more detail for further reference.

Rubber hand illusion is an idea that, by and large, was somehow transformed into multi-sensory rubber hand illusion, and they now want to put it into prosthetic arms to make users believe the prosthesis belongs to their bodies.

With that, rubber hand illusion goes to market1)As in: piggy goes to market..

This is not really that fascinating. While I am not interested in prosthetic arms because I find the field fascinating, I have been drawn into the field due to circumstances. And as much as you feel that I am locked into this constraint space of shared idiocies, dreams, hopes and failing hardware together with you, in some type of brotherhood by bad fate, you may also realize you are locked into this with me, as consequence of bad fate. Those then are also circumstances. As I deal with it, you may also have to find a way. If you think that is uncomfortable, send me a mail, so we may talk about uncomfortable a bit.

The ultimate consquence of this piece of reflection is not at all bad, however. We will see just how too much "ownership" has bad aspects as well. It risks to slip prosthetic hands into a domain where it is subject to the most vicious decision making that there is: tyrannic and wilful, impulsive and emotional decision making within one's own very personal domain of body or body image with owned body part dependent urgencies and requirements. To withstand these storms, a  prosthetic arm has to withstand not only the physical requirements of real life use (which it normally does not to a degree that will make your jaw drop), it also has to be acknowledged in that capacity by manufacturers and care-givers, emergency teams or repair units, where none of similarly urgencies are currently provided.

To even reach a level of "tool", to be useful enough to be accepted as technical solution (not as embodied "owned" limb), a typical prosthetic arm may have to undergo a most serious metamorphosis, from commercial parts (link)(link) to tuned and optimized parts (link). If you are in R&D and want to do something good in support of arm amputees, it may be relevant to address actual issues such as failing devices or phantom pain (link), before going all out on a limb and drag ill-defined concepts to a domain where they may wreck more than they really help.

CE-marking or norm

The CE-marking establishes that a particular item or product conform to European product law in relation to health, safety, and environmental protection standards [link].

As this text is not public or may be hard to get into the public eye, why not just go ahead and drag it out. I started to be interested by the backgrounds of what our prosthetic limbs and their technical documentation ideally could be already a few years ago [link].  So, a few blog posts here do have a long history, longer than others, and were assembled over quite a period of time.

Auf ihrer Webseite behaupten Personen von Promembro, "Wir sind die Lobby der Prothesenträger/innen und schaffen ein Schweizer Netz, das auf den Schutz der Interessen der gesamten Prothesenträger/innen spezialisiert ist: Jugendliche und Ältere, Sportler und Nichtsportler, Aktive und Rentner, Kranke und Gesunde. Wir vertreten die Anliegen unserer Mitglieder sowohl bei der Bevölkerung als auch in Politik und der Verwaltung. Die Institutionen wie Procap oder Pro Infirmis sind zu gross, um sich der kleine Zahl der Prothesenträger genügend zu widmen." - Grundsaetzlich sind sie an einer Motion interessiert [link][link], an der Balthasar Glaettli und Roger Golay beteiligt sind.

Damit moegen diese Individuen glauben, wer immer sie seien - aber meine Interessen vertreten sie mit Sicherheit nicht. Sie sind niemals "die" Lobby. Da sie behaupten, sie schaffen "ein Netz", das die Interessen der "gesamten" Prothesentraeger vertreten, ist die Behauptung (oben) bereits bewiesenermassen falsch. Sie vertreten mit Sicherheit meine Interessen, insbesondere diejenigen, die ich relevant finde, nicht. Dazu fehlt es erwiesenermassen an Verstaendnis, und vor allem Respekt. Vielmehr verwenden sie die laengst abgeschmackte Piraten-Metapher, um werbewirksam auf sich aufmerksam zu machen.
