The Becker Lock Grip hand looks good. It is not the most anatomically detailed version of a silicon painted glove hand representation that requires to stay out of trobule - instead, this is industrial design meant to be and designed to be used at all times.

Carnes arm - hand function

After I discussed the history of the Carnes arm, here is a description of one of the more intricate mechanisms found in later Carnes hands [4]. I find it absolutely fascinating to also consider how history seems to repeat itself.

The situation escalates. This is a bit like the old Photoshop Ping Pong.

I had just completed spray painting my sockets.

But then, after Becky had e-mailed me about this earlier and now that she and Holly had posted their projects' work, their old worn out wooden look started to sink in and I started to like it in my own way. Decay, an organic feel to being used up, but also resistance to adversity, ongoing presence after physical adversity - showing that that is how my arm feels inside, how I feel inside started to become an issue.

But I never liked wood to be a structure that is visible as my prosthetic arm. Wood is too tangible, too physical, to concise and too specific for my taste. Emotionally it would pull me down, I had tried that earlier. I had already figured out also that I needed my prosthesis to transcend known materials.

I wanted something artificial in a sense that no direct association but only references would be possible. The more one digs into the emotional aspects, the more the situation is deadlocked: How do I present strength when there is weakness? How do I present relative comfort in suffering? How to be boldly shy about a clearly visible item that is supposed to be hidden? How to show prosthetic prowess when all that happens is prosthetic decay? What about not telling the truth is lying? What lies are comfortable? If things are bad, why not make them look a bit bad? If things are ugly, why not touch up visible ugliness? Why paint clear symbols, flags or shapes when really animal-like gut feelings dominate us? What design hides constantly added small defects best? What lessons have I learned from previous applications of added decay?

So I sand papered the previously red socket. Then I applied structured rubbery paint to it, stuff that would create a bumpy structure. Then I sprayed it black. After that, I applied this beige yellow greenish color. After it all had dried I sandpapered off some of the structured bits leaving valleys coated with all colors and mountains eroded.

This resulted in a cool somewhat corroded looking appearance. All of a sudden, my arm had obtained a very new quality: it did not get more beautiful in any average sense, but so much more lovable. To me and in relation with my prosthetic arm, a new feeling that I had not expected initially. Starting to modify prosthetic appearance allowed me to eventually get here. This look, this is really close to my heart.

Virtual artistic collaboration. Thanks for the inspiration :)

This continues my Red Arm / Technical Design study, a practical attempt at finding the best look for my arm. This came after I realized that cosmetic standard issue prostheses make people nervous and that these make people respond to me in stereotypically distressing ways. Rather quickly I found out that the appearance of the prosthetic arm can be instrumental. As there is no theoretical way to establish these, trying out has become my favorite means.

After the Red Arm / Red Hand had worn out a bit, a re-paint appeared to be in order.  As you may realize I am currently inspired by the design of 9. So I went to our local Jumbo to check paint colors. And what did my bleary eyes see? Industrial / Functional/Technical Paint! Heat and scratch resistant white glossy coating for heaters. Beige-green anti corrosion coating. And ultra resistant black matte coating for grills.

I was delighted. Here we go :)

To allow for a firm rubbery cover that I can cheaply replace I removed the factory issue rubber that covered the V2P Prehensor claws and cut up nitrile glove fingers (make: Atlas 370).

Here's how.

The standard Otto Bock wrist uses a sub-16.000mm cylindrical bolt. Our own wrist units adapt to that. The V2P - as well as other US-American terminal devices - ships with a 1/2-20 UNF threaded bolt.

What to do?

Becker Lock Grip hand - gloves

Prosthetic hands are usually equipped with expensive gloves. They look cheap, they feel cheap, they probably are made cheaply - but they cost a fortune. And if they don't look cool, it's not cool. Still:

  • For cosmetic gloves, I prefer Regal Prosthesis gloves. I feel as if they outperform Otto Bock's products any time. But then, cosmetic gloves only are so and so cool - not completely.

The Becker Lock Grip size 8 is so standard that several other options are available:

  • For cool looking gloves, self made gloves are the thing to make and the thing to wear. If you are creative, why not use a skin photo of your own complexion or actually your other hand and have that printed on a shirt? Then use that fabric to make a glove. That type of fabric printing, these days, is dirt cheap.
  • For technical gloves, I tried the Atlas 370 nitrile gloves and I like them a lot. For my size 8 hand, I use gloves sized S (small).

ADL (activities of daily living) are a roundabout way measure by which rehabilitation outcomes are measured. They contain household activities or housework, everyday activities, work and play, eating and laundry, cleaning and fixing up stuff. And, what is good enough for rehab outcomes sure is good enough for me. So I figured why put up with blurred concepts when we can be far more concise?

[this is comprehensive, it really is - this time there are lots - and I mean *lots* - of images - puhleeze, wait until they are loaded, get a drink, go to the bathroom, whatever, *then* read]

Diesen Artikel gibts auch auf Deutsch.

My current setup so far only contained two Otto Bock System Hands - this model is a voluntary opening hand with a clamp mechanism. The Otto Bock hand is very nice and useful but obviously current myoelectric hands are more fun due to their adaptive grip options - far too expensive for that bit of electronics they contain, not too functional as they are slow to react, very cumbersome, and due to socket issues painful and not possible for me to wear right now - but far more fun. So I am in search for a good prosthetic terminal device.

Dan Horkey of Global Tattoo Orthotic Prosthetic Innovations (GTOPI) has taken prosthetic socket coolness to the ultimate - chrome! He is testing the new chrome finish and hopes to make it available soon so you can now get yours fully chromed.

This is way cooler than anything there was before. It goes way beyond my beloved chromed cuckoo clock art project. It is so real you could probably use it as a shaving mirror.

This one is the real deal:
