Inner Ear Stimulation for Parkinson's Disease
(VEST Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This study investigates whether vestibular (inner ear) dysfunction is a cause for poor balance in Parkinson Disease (PD), and whether inner ear stimulation with a small device may improve balance. This study will involve clinical testing, brain imaging, and an interventional treatment device for symptoms.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is inner ear stimulation for Parkinson's disease safe?
Non-invasive brain stimulation techniques like transcranial electrical stimulation (tES), including tDCS and tACS, are generally considered safe when responsibly manufactured and legally marketed. Studies have shown that these devices, which are used for various conditions, have output levels well below those of many FDA-cleared devices, suggesting they do not introduce significant risk. In clinical trials, no severe adverse events were noted, although slight skin redness under the electrodes can occur.12345
How does the inner ear stimulation treatment for Parkinson's disease differ from other treatments?
The inner ear stimulation treatment for Parkinson's disease is unique because it uses a non-invasive neuromodulation device that applies electrical currents to the brain, unlike deep brain stimulation which involves surgical implantation. This method is portable, cost-effective, and aims to modulate brain networks without the need for surgery, potentially offering a safer and more accessible option for patients.36789
What data supports the effectiveness of the treatment Inner Ear Stimulation for Parkinson's Disease?
Research shows that non-invasive brain stimulation techniques like transcranial direct current stimulation (tDCS) have shown promising results in improving nonmotor symptoms such as depression and cognitive dysfunctions in Parkinson's disease. These techniques are also being explored for their potential to improve movement disorders by modulating brain networks.5671011

Are You a Good Fit for This Trial?
This trial is for people who have had Parkinson's Disease for at least 5 years and are experiencing balance issues. They should be in the Hoehn & Yahr stages 1.5-4, which measures disease progression. Those with other conditions that mimic PD or ear problems like Meniere's disease cannot join, nor can those with brain lesions on MRI, metal implants that affect MRI safety, severe claustrophobia, exposure to too much radiation recently, pregnant or breastfeeding women, or active mood disorders.Inclusion Criteria
