With the current on-going search for "tricks" or "solutions" to "solve" manual problems of ADL (activities of daily living), one very large unexamined domain is how to live life without a prosthetic arm on.

I was surprised to see that (according to a recent news article [link]) an Otto Bock Michelangelo hand was required to reclaim one's role as photographer:

"This Michelangelo is quantum leaps ahead of anything I have ever been able to do before," Wigington said.

The hope is, with training, Wigington can reclaim his position as the family photographer.

(quoted from http://www.wthr.com/story/20111441/indianapolis-minister-first-to-get-revolutionary-prosthetic on Dec 13th 2012). 

It appears that in over some 20 years of being a right below elbow amputee, Dave Wigington has not been able to figure out how to use a camera well, swift, fast and proficiently.

It appears that in over some 20 years, one now requires a particular "bionic" hand to be a family photographer.

This is extraordinary.

See, it took me exactly a day or two after the amputation to figure out that my camera still worked the exact same way. That was before "bionic" prostheses came along.

So there is a big difference between my own experience and between Dave Wigington's experience.

Seeing that there are obvious differences in what people think they can or can not do, I tried to see where the problem might be.

From there, I will illustrate some ways of taking photos singlehandedly, with the left hand, and / or with my prosthetic arm. If Dave has problems, other people may find this instructive. Who knows.  Read More

I am sure there must be dozens of ways to drill in screws with just one hand.

There are magnetic screw divers or drill bits. Maybe a drop of glue that is easy to rub off later.  Or fixing the screw head with the index finger.

Here I use sticky tape.

I show how I control-click through a list of file with one hand. Shift-click works the same.

- The thumb operates the control key.
- The hand pushes the mouse.
- The ring finger clicks the left (regular button 1) mouse button.

The motions are relatively subtle and relatively precise.

Manualization of the body and time and effort spent to implement it [options for people missing an upper extremity part]

If a part (or more parts) of upper extremities are missing, absent function can be replaced to a small degree.

Replacing at least some basic aspects of a hand's function with the rest of the body and immediate environment is what upper extremity amputees including myself do every day.

There are a few questions along the road, but other than that, "manualization of the rest of the body" as well as manualization of surrounding environment is what is going on. There are simply no other options and interestingly, problems are similarly in nature regardless of the type of solution one chooses.

When evaluating a prosthetic hand, when doing evaluation of a prosthetic arm or hook, when evaluating myoelectric or ""bionic"" prostheses such as iLimb, BeBionic or Michelangelo by Otto Bock, then this should be considered thoroughly.

Of course one can spend all day theoretically analyzing grip options and comparing different options or, just do it.

It is intriguing to see recent surges of apparent ADL (activity of daily living) demonstrated with so-called "bionic hands" (including Otto Bock Michelangelo hand, iLimb by TouchBionics and BeBionic by RSL Steeper). For the most part, these are not a demonstration of a need to wear any of these hands.

There are people that realize that not all advertising really means the offered solution works. Hand transplants - as useful or useless as some of the new 'bionic' hand gadgets - are known to fail and some people take a while before they verbally and publicly admit that body powered hooks are not as bad after all. As Jeff Kepner said in a video interview - with a hook you know what to expect. The difference still is that 'bionic' hands can be put aside - whereas hand transplants cannot.

Stories like that makes you consider however just how much can be done without ANY prosthetic or transplanted hand. Just to get a feel for the functionality and to fully feel with the extremity.

Videos are at least somewhat non-negotiable, and therein lies their beauty. Conversely you will hate me for the simplicity of (at least some of) these. So below is a demo of actual ADL using the arm stump only. Any of these may be also carried out with a prosthetic arm, but in many instances they work a lot better with 'just' the stump. Old orthopedic surgeons used to say "the best prosthetic arm is the stump itself" and it seems that the extra time my surgeon spent on my arm to fix it up proper and neat was time well spent. I find that the stump he left we with is in fact useful - long enough and sensitive.

Which watch?

I have issues regarding watches.

I will not be able to wear just about any wrist band as I have to be able to operate it using stump ot prosthesis. A heavy or large watch is not optimal as I tend to overuse my complete left arm anyway. And the watch should be reasonably water proof as the last thing I want to do is to take it off / put it on all the time. I do lots of sports and so luxury watches are not exactly what I will be buying.

Here is what works.

When I tried to play the guitar right after the amputation, I was surprised at how little control my stump really has. Even now the prosthesis is no match for the string control I want to achieve. But lucky me, Eddie Van Halen established all of that already and today, hammer-on an pull-off go a far way.

So after you listened to some initial samples, here is how I tried to do that.
