The Booth Gardner Parkinson’s Care Center is conducting a randomized, double-blinded study for patients with Parkinson’s Disease (PD) who have the wearing-off phenomenon on oral levodopa therapy. The purpose of this study is to see if the Earstim device can improve PD motor function symptoms. The researchers will study the safety related to use of the device, and if any improvement in symptoms continues after the therapy has stopped.
