Investigating neuromodulation techniques for improving gait in Parkinson's disease

Exploring the Possible Beneficial Impact of Non-invasive and Invasive Neuromodulation on Freezing of Gait in Parkinson's Disease During Different Ambulatory Complexities: An Electrophysiological and fMRI Study

Not applicable Interventional China Medical University Hospital · NCT06505460

This study is testing different brain stimulation techniques to see if they can help people with Parkinson's disease improve their walking and reduce episodes of freezing while they walk.

What this trial studies

This study aims to explore the effects of both non-invasive and invasive neuromodulation techniques on freezing of gait (FOG) in patients with Parkinson's disease. It will utilize an artificial intelligence algorithm to identify and quantify FOG episodes through video and pressure data during walking tasks. Additionally, the study will investigate the underlying neural mechanisms of FOG using advanced electrophysiological methods and fMRI. Finally, it will assess the impact of interventions such as transcranial direct current stimulation and deep brain stimulation on gait performance in these patients.

Who should consider this trial

Good fit: Ideal candidates include adults aged 20 to 90 diagnosed with Parkinson's disease who experience freezing of gait and have not achieved satisfactory control with medication.

Not a fit: Patients with advanced Parkinson's disease at Hoehn and Yahr Stage 5 or those with severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for managing freezing of gait in Parkinson's disease patients.

How similar studies have performed: While some studies have explored neuromodulation techniques in Parkinson's disease, this specific approach combining AI and various neuromodulation methods is relatively novel.
