First, my thanks go to the testers: your comments have led to a better program.

If you wish to take part in the survey (both PwP and non-PwP are welcome) go to:

http://www.parkinsonsmeasurement.org/PDMeasure

There you will see "Getting started in just 5 minutes" and an explanation of how the project runs.

Going beyond that you can repeat the test as often as you want.

If you have any problems, please get in touch.

What are the objectives of this survey? To measure the extent to which the tap test results:
- are affected by learning, time since last medication, disease duration and gender;
- distinguish between PwP and healthy people.

Next week I'll begin a series of surveys that will look at the role of the environment in PD.

If there's any subject you would like polling, please get in touch.

John
