Just a quick note to say that I'm still looking at this, but progress is slow.

Here's a graph of my head movements over a 5hr period.

The head was chosen as the position of the accelerometer because I have no tremor there. This means that more movement is good. Whereas if the measurement is done on a place that tremors it confuses the issue.

The test was done using the Arduino/accelerometer system with my software as described in the previous post.

Time 0 is:
- 6 hours after my last medication;
- the time at which I take a new dose (Stalevo 75mg);
- 4hr 40min after eating.

I spent the 5hrs reading and dozing.

Each dot represents the average acceleration magnitude over one minute of readings taken every 0.1 second.

Although there's a lot of noise, I think the following features can be seen:
0-40 minutes: increasing acceleration (=symptom relief);
40-120 minutes: plateau;
120-180: decreasing acceleration;
180-280: there's an increase followed by a decline in movement that I can't explain.
