I'm attaching the technical paper I wrote describing the development of a proposed new test for Parkinson's Disease.

Because of forum limitations on the size of attachments it was necessary for me to greatly reduce the size of the report by removing entire sections and most of the graphs. Please send me a private message if you'd like for me to email you the full report.

I know that we have to watch about commercial interests trying to take advantage of us but this does not appear to be the case. This is more like Max and his work on a new type of walker. We can always call "foul" at a later date, but for now I'm all for it.

The simplicity is good and would allow for some pretty detailed self monitoring.

Steve,

I'll be interested in knowing how your 3LT results correlate with my side-to-side tap test:

If I understand your test correctly, it just takes a few seconds to complete. Whereas, mine takes a minute.

John, I have a tear in the meniscus of my right wrist so certain tests tend to cause me a bit of pain. I got the following results:

Time: 5:23 pm
John's Test: LH 23.98, RH 27.36

Time: 5:25 pm
3LT Metric: 97

Time: 5:30 pm
3LT Metric: 72

I ran the 3LT test twice so you could see how stressed I was immediately following your test and how everything had calmed down 5 minutes later.

Interesting, John. How would you classify the results from your test?

Steve

I'm posting these graphs in case anyone is interested. If nothing else, they're pretty.

What they are is something called "Cauchy wavelets". I prepared them from the 3LT test data taken from a friend and myself.

My PD symptoms are somewhat worse than my friend's. My results are shown on the bottom graph.

I've been a bit busy. Anyway, I wanted to share this with the group.

[QUOTE=Songfellow;947967]... Did you ever wonder why the rhythm is often around 70 beats a second? Like a heart beat. Familiar and comfortable.


Did you mean "70 beats a minute "?

[QUOTE=rempatterson;1160149]geeez! After all these years since I first posted that error, you caught it! THanks so much.

Our Vision: The 3-Line Test
August 5, 2015 (Revised)

Much of nature displays patterns that are recognizable to us in a "comforting" way. There is a rhythm to life that we take for granted.
Please pause for a moment and think about it? Whether you believe in God or not some
observations seem appropriate.
Maple leaves have five fingers. We have five fingers. Clouds form shapes that once intrigued us as children. Most animals have heads, eyes, ears, four limbs and a rear end that is often adorned with a tail. Cracks in pavement look like the Grand Canyon viewed from space.
Humans, animals and plants are born, live, die and depend upon reproduction to insure
survival of their genes.
Have you ever wondered why everyone's handwriting is different? Why do we have a head?
Couldn't the brain be spread around to other places? But wait... the head might be considered as support for our eyes, ears, and mouth. Those are the things that keep us alive. Not our brains.
Perhaps the brain exists to act as a resource for those senses. Would you argue that bacteria live because of their heads? Good luck with that.
Patterns. Why does the body shake when confronted with danger? Or perhaps the question is,
“Why does the body ALWAYS have a tremor?” Hands, tapping feet, eyes blinking, pupils
contracting, heart beat, breathing... hmmm. To some people the clouds make music. Why do we LOVE the thump, thump of a bass drum? Did you ever wonder why the rhythm is often around 70 beats a minute? Like a heart beat. Familiar and comfortable.

Our bodies are a complex mechanism of a thousand-fold interacting systems that are kept in harmony by a master drummer. It keeps time. The rhythmic signatures of all of our body's mechanisms playing as an orchestra show up as a mild tremor in our hands. It’s a complicated engine that "hums" when in tune and sounds "wrong" when a piston slaps.
The 3-Line Test tries to break that "hum" down into its constituent signals so that one day a doctor might diagnose illness from a patient’s handwriting.
That's our vision.
