BECKER Hands have an adaptive grip. This is something people don't know. To wear a Becker hand, all you need is a body powered arm.
These days, people appear to show off their prosthetic "bionic attempts" by - don't laugh - holding on to a water glass.
Sure, sure, But, why? Is that so important, so hard, so decisive to spend thousands of dollars to hold on to a freaking glass, can or bottle? I don't get it.
At any rate, let's start here.
Hooks and myo arms are alright - but there are absolutely no control and drop issues with body powered Becker hands. Conversely, dropping a beer glass with a myo arm is a realistic risk that you run. Cheers though.
The grip that you see here? Fingers wrapping around the glass? That's called an adaptive grip.
Surface finish and looks
I already tried some colors. When I paint it white, people will ask me whether they saw that hand on TV and whether I am indeed wearing the latest Otto Bock Michelangelo hand. I am not sure this is a compliment so I'd tell them, no, this one is even better.
The Becker hand is a lot lighter, a hell of a lot sturdier and far more available - 24/7 without recharge, mail order, you name it - than competitor products (if at all there are any).
Grabbing tooth brush
Adaptive grips require cool mechanic setups, not necessarily the extra weight caused by myoelectric controls. This is one of the great misconceptions of our times.
The Becker hand grip is as adaptive as they ever come. It has better articulation, functionally, than some "bionic" hands.
I am sure you would want your tooth brush to be gripped as well as my tooth brush is. My tooth brush is very happy about this and still works as it has not fallen down too often over the years now.
Becker hand with CENTRI cosmetic PVC glove
Even a worn down PVC glove (CENTRI) works perfectly well with the Becker Imperial hand, here an illustrative example with me carrying the espresso with my prosthetic hand and using my left (intact) hand to open / unlock all the doors along our work place's security corridors.
Grabbing my wallet
I had not had such a firm grip of my wallet since the amputation.
Grabbing round objects
I started to grab round items very early into using this hand. This is a demo just minutes after obtaining my first Becker Lock Grip hand.
As you can see I am quite hesitant to this new grip. Will it hold? Will the grip surround the object and be firm enough?
Grab and hold a glass
This is extremely comfortable - to have the grip wrap around and about 6 kg pressure on the tips. The hand is powerful indeed.
Grabbing can using Becker Lock Grip hand. Smooth, fast, with one sweep, silent, adaptive and very cool.
Picking and grabbing grapes is one of the coolest benchmarks for a prosthetic hand. Don't try this at home, kids.
Grabbing a cup
Grabbing a cup - such as shown here - is an absolute no brainer with this Becker hand. I want you to see how the fingers wrap the object in what is an *adaptive grip*.
Speed performance demo
I just sat down and figured you may want to compare your prosthetic hand against this so in case you want to test yours, here's how that worked when rearranging some soft balls:
Ultimate test - egg handling using Becker Lock Grip hand
Demonstrating egg handling using a mechanical Becker Lock Grip hand. If you can do that, you can fry your own eggs :) As you see I am not only one hungry person (6 eggs as part of my breakfast) but also, opening eggs that way is a no-brainer (check the frying pan - no accidents there). If you must know - the round white thing to the right (in the frying pan) - that's not an egg shell, that is an onion (another round object that I sliced up using the Becker hand).
Precisely this is why I am not sure the DARPA invested their tax payer's money correctly by *solely* supporting myoelectric technology. Otto Bock also seems to currently neglect the development of sophisticated hand or hooks for cable controlled arms. This is wrong in my view. Cable controlled arms go a far way. You just have to walk that path. This arm is light, robust, does not at all require batteries or electricity, it is very affordable and it also looks technical. The Becker Lock Grip hand can be also ordered customized. If you neglect or ignore this, how are you gonna fry your eggs? Seriously?
Cutting up tomatoes
That is an issue. Not all hands do that similarly well. And cutting up tomatoes is a must.
Generally, people forget that iLimb, BeBionic or Otto Bock Michelangelo hands are relatively cumbersome, expensive, thus hard to obtain, unreliable and heavy weight options for a limited adaptive grip which is by far better done using a Becker Imperial or Becker Lock Grip hand.
A far more comprehensive overview over adaptive Becker hand grip for everyday tasks (ADL, activities of daily living) is given here.
