Finally something to write about. Nothing exciting, but not "nothing" either.
This morning Vicky (Maddie's granddaughter) left to go back to Stellenboch University. I sure hope she can stick to her studies of Math and Physics, and not change her major to boys.
Maddie and I decided to go to the Botanical gardens for some exercise. Last weekend Maddie did the 5km (3.10 mile) George park run through the Gardens. Here is proof....
Notice the thousand yard stare of an exhausted athlete.
I told about Maddie showing me the hard part of the run through the woods. Today we stayed on the easy part of the run.
The weather was cool, windy, and beautiful skies. We appealed to the gate guard to let the poor, helpless, cripple, park his car inside the Botanical Garden. Inside the Garden are two large grassy plains, and a hill that is called the labyrinth. We parked in the one big grassy field.
The labyrinth is a 10 meter high hill with a spiral path leading up to the top, and another spiral path leading down. The paths never cross, so you never meet anyone on the path.
Here is a Google map of the Labyrinth Spiral and the one big field.
First I walked the length of the grassy field a few times with the walking sticks. They are better than the cane for walking fast on uneven ground.
My prosthesis is designed to lock the knee when weight is on the heel, and to unlock the knee when weight is put on the toe.
When walking on uneven ground, one step may have a clump of earth under the heel, so the knee will never get weight on the toe to unlock the knee. So just when you need to swing the leg forward, it won't swing forward because the leg is stiff, and doesn't leave the ground. The opposite is true if there is a clump of dirt under the toe. As soon as you put any weight on the foot, the knee unlocks, and the leg collapses. After quite a bit of walking I figured out that taking LARGE steps greatly increases the angle of the prosthesis foot on the ground, which greatly increases the knee breaking loose if something is under the heel, and helping hold the leg stiff if something is under the toe.
I then went to the Labyrinth, and practiced walking up slopes, and down slopes. I used a walking stick in my right hand, and the cane in my left hand. Once again I found large steps to be a big help for up slopes.
If the down slope is steep, I found that a method similar to going down stairs works best. First put the prosthetic foot down in front, then because the weight is on the heel, I must use LOTS of force to move my stump forward to break the knee loose so it collapses. (OH NO...I'm going to die.) then quickly move my good leg to prevent me falling on my face. It feels very much like I save my life every step.
Then I got a bright idea. What if the leg never locked? So I changed the settings so the leg was floppy. It just would swing free. The only thing to keep it straight was to snap it forward, then hold it against the ground with strong back pressure. If the back pressure was released, the knee collapsed.
Now I had no problem getting the knee to break and bend. This allowed controlled collapsing.
I did 2 more up and down the Labyrinth.
The view from the top was fantastic.
A couple at the top took a picture of Maddie and I.
Here is a panorama of the view from the top.
I walked fast with the knee loose back and forth the length of the big field, then with Maddie close by, I "fell" and got up by myself twice.
Then home for a welcome shower, and a movie. "Now you see me".
