Causes and outcomes of freezing of gait in Parkinsonian conditions
Official title: FREEZE-Path Cohort: Etiology-Phenotype-Outcome Pathway Study on Freezing of Gait (FOG)
Run by Tianjin Huanhu Hospital · NCT07386015 · Data updated 2026-11-12
This registry will collect long-term clinical, gait, and video data from adults with freezing of gait or related parkinsonian conditions to see if different causes lead to distinct symptoms, walking patterns, falls, and disease progression.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 30-85 with freezing of gait or non-freezing gait/balance impairment and a diagnosis of Parkinson's disease or a related parkinsonian disorder who can complete gait and balance tasks and provide informed consent.
✕Probably not a fit
Patients with severe dementia, severe psychiatric or medical conditions affecting gait safety, recent major medical events, inability to comply with follow-up, or refusal of video/speech recording may be ineligible or unlikely to benefit directly from this registry.

What this trial studies
This is a prospective, observational patient registry led by Tianjin Huanhu Hospital that enrolls adults with freezing of gait, gait and balance impairment, or those at high risk for FOG. Participants receive usual clinical care while study staff collect baseline and scheduled follow-up data including questionnaires, standardized gait and balance tasks, objective gait parameters, falls history, and video and speech recordings. No experimental treatments are assigned; data are recorded during routine visits and follow-up assessments. The registry aims to link underlying causes (Parkinson's disease and other parkinsonian syndromes) to clinical phenotypes, gait signatures, and long-term outcomes.
Why it matters
Potential benefit: If successful, the registry could help clinicians identify who is at higher risk of falls or rapid progression and guide more personalized management of gait problems.
How similar studies have gone: Previous observational cohorts and smaller registries have described clinical patterns and risk factors for FOG, but comprehensive long-term, multi-diagnostic registries remain limited.
