An International Multimodal Protocol for Assessing Freezing of Gait in Individuals Living with Parkinson's Disease

What this Trial Is About

Researchers are working to develop reliable and accurate measures that doctors and patients can use to assess the severity of Freezing of Gait (FOG) in individuals with Parkinson's Disease. This study focuses on creating both clinician-reported and patient-reported outcome tools to better quantify FOG symptoms. These tools aim to help clinicians and researchers understand FOG more precisely and improve evaluation methods. Participants include groups of Parkinson's patients with and without freezing of gait. Patients with FOG will be monitored using sensors called Opals placed on their shins, feet, and lower back. Additionally, those with FOG will wear an Axivity monitor on their lower back continuously for seven days to track mobility. The study observes participants in both ON and OFF medication states to capture detailed gait data. During the study, participants will undergo assessments in controlled sessions while wearing the sensors. The Axivity device collects continuous movement data over a week, even during sleep and showering, as it is waterproof. Researchers will validate the new clinician-reported outcome tool by the end of 2025 and assess how important the FOG symptom is to patients. Total participation time varies based on individual assessments and monitoring periods.
