Sep 05-09 2016 - Pipe legs and Driving

Sept 05 2016
I have been trying to find a way of standing to do dishes, that does not entail balancing on one leg. I came up with a piece of PVC piping that my stump fits into, and I flared the top. You can laugh, :-) but I can stand for hours now.

I also have been working on designing a socket that allows for stump volume variations. By being able to vary the volume, I can keep it tight all the time. I built this.

Again, you can laugh, BUT,... it does not hurt. No Pain. Next is to get both together, and then make a way for the pipe not to fall off when I take a step.

Online I found a socket that looks like it would work, but they want house prices for these things.

I went to the prosthetic place today. I told Bradley (my prosthesist) That I want a pain free walking leg by the end of the month. We discussed many, many options.
He made another cast to make another socket. It should be ready by Friday.
We plan on making this socket like a normal solid socket, but without an end on it, so the bottom is open, and also put a slit down the side, and use clamps to tighten it on tight.
I think the best clamps/straps will be similar to ski boot bindings.

My stump pain seems to be increasing, not decreasing. I think the stump is shrinking in length, which put all the muscles, scars, and skin at the end more forceful against the bone end.

I spent a few hours with the surgeon today. He thinks we might somehow "pull" the stump end to stretch the muscles and skin to relieve some of the force on the end of the bone.
We need to think on that.

I'm just back from a few hours with Bradley, the prosthesist. We tried on the new socket. It is similar to the old , hard sockets, but is split down the side to allow adjusting it's volume.
He left the bottom end closed, but wide enough that the stump never touches the bottom part. That way we can still apply a vacuum to the bottom of the stump if needed.
The socket was very tight at the top, and floppy at the bottom. Just like it should be. It caused no pain. He had made this one out of very transparent plastic, to allow seeing where it is tight and where loose by noting skin color.
Hopefully I'll walk away on the new socket next Wednesday.

This whole cancer/amputation thing has resulted in me staying away from Texas for so long that my Texas drivers licence is expiring. It will be cheaper for me to get a South African license, than to travel to the states to get a new Texas one.
I now get to experience the South African bureaucracy first hand. 100% bureaucratic bullshit. It should take a month or two. depending on how many times I flunk the driving test. Without bribing, it usually take a few flunks. Flunks pump up the stats for the inspectors to prove how hard they work, and how many tests they have to do each month.
I just chatted with a lady that flunked her driving test 7 times. Seven is a lot even for South Africa. Three seems to be about average.
I have to first get a learners permit, then I can apply to take the driving test.

I just had coffee with a friend at a local restaurant. It was nice to get out and interact a bit.

I have been looking at the paralympics. I look at all the people competing, and find someone worse off than me. Then I look more, and find someone worse off than that person.  Then look some more, and find someone even worse off than that person. It seems there is always someone worse off than someone else. Which I guess really means that I am MUCH better off than so many others.

I read some good observations regarding the Paralympics:

 We could see blind runners taking a course unaided thanks to headsets which can watch for hurdles as well as providing left and right instructions.
(The step from driverless cars, to blind people walking, is not a large step.)

Actually our wheel chairs are like Formula One cars; they're the absolute cutting edge of technology. Thanks to carbon-fibre chairs and precise engineering, the wheel chair weight is down to just 2kg. 
(Mine weighs 18kg.)

The Paralympics is wedded to science and technology. In the paralympics charter, science is a huge part of it. It’s all about enhancement, it’s all about making people better. 
(Able bodied people will soon need body enhancements, or get left behind by disabled people.)

The ‘Brain Sled’ was designed by engineering students at Imperial college, and uses electrical signals in the brain to ‘steer’ a sled in a bobsleigh event. Now we can have totally paralyzed people competing in sports. 
(Is this still an "athletic" competition?)

The current exoskeleton can only walk slowly, and the expensive, computer-controlled hydraulic machines is used to deliver the health benefits of walking to paralysed patients. 
(Isn't an exoskeleton just a step up from a fancy prosthetic knee?)
