The Parkinson Pipeline Project has been running an opinion survey on the use of sham surgery as a placebo control in clinical trials.

We hope to get as many opinions as possible. If you haven't responded yet, you can answer the short survey by going to www.pdpipeline.org and click on the "Survey on Sham Surgery" Link on the homepage.

Thanks to all who participated. The survey will close on August 31st and the results posted soon after.
