The microprocessor is an Ardulog. The accelerometer is a MMA8452.

I'm looking for a proxy measure of bradykinesia in Parkinson's. This is made difficult because:
- more movement which is good where it is desired needs to be differentiated from tremor where it is not;
- strongly intentional movements (such as walking a mile) need to be differentiated from weakly intentional movements (such as changing your position on a chair).

To judge whether an approach is successful I expect to get a graph of movement against time following a levodopa dose that is similar to those you get from tap testing.

For this run I positioned the accelerometer on the back of my head, resting in a turned up ski hat.

Has anyone on the forum played with a smart phone app that stores accelerometer data and graphs it?

This may all seem to be arcane, but if we had better ways to measure PD, we could advance faster the search for better therapies.
