Validation of cueStim for Reduction of Freezing of Gait in Parkinson's Disease

The goal of this clinical trial is to learn if the cueStim device can reduce the duration of freezing of gait (FoG) that occurs in patients with Parkinson's Disease. The study will compare two modes of operation of the cueStim device; both modes of operation use the same wearable device. The purpose of the study is to compare how the two modes affect symptoms across study participants. Because this is a research study, it is not yet known whether either mode reduces symptoms. Participants will: * Be randomized to one of the two modes available on the cueStim device * Wear the device for 4 weeks as they go about their daily life * Complete daily diary entries to document symptoms, falls and overall experience * Check-in with the clinical site throughout participation * Complete a final follow-up visit
