The purpose of our study is to evaluate Vibrotactile Coordinated Reset stimulation (vCR) and its effects on Parkinson's symptoms. vCR will be administered with a device called the Stanford Glove. vCR is expected to provide patients with a non-invasive alternative to the most widely used treatments such as Levodopa and/or deep brain stimulation. Patients will be followed for 14 months.

The purpose of this study is to test the efficacy of vibrotactile coordinated reset stimulation on human subject participants with Parkinson's disease and inform the investigators on whether unilateral stimulation could be as effective as bilateral stimulation at producing clinically significant improvements in symptoms.
