SCH: Context-aware Freezing of Gait Mitigation in Real-world Setting

People with Parkinson's disease (PD) may experience a walking problem called freezing of gait (FoG) that can interfere with the person's ability to conduct daily activities. FoG has been described as feeling like one's feet are glued or stuck to the floor. Drug treatments for PD rarely improve FoG. Researchers have found that vibration therapy may help improve FoG. The purpose of this research study is to test the safety, tolerability, and effectiveness of using a wearable device (UG motion sensor, that is the size of a watch) that will recognize FoG and then send a signal to another small watch-like device (PDVibe3) to deliver a vibration stimuli to participant's feet. The researchers believe the vibration stimulus (which feels like a phone on vibration mode) will help reduce FoG in persons with PD. The study is open to people who have been diagnosed with Parkinson's disease, have FoG, and meet the study entry requirements. The PDVibe3 is an investigational device, which means it has not been approved by the U.S. Food and Drug Administration (FDA). The UG motion sensor is also an investigational device.
