What this trial studies

This project focuses on developing and validating a wearable sensor designed to assist patients with dysphagia related to Parkinson's disease. The study is structured in three phases: first, enhancing the sensor's battery life and reducing its size; second, conducting focus groups with patients to gather feedback on usability; and third, testing the sensor's ability to detect and prompt swallowing in a small group of participants. The goal is to create a practical tool that can improve the quality of life for those affected by these symptoms.

Who should consider this trial

Good fit: Ideal candidates include English-speaking adults aged 22 and older with a diagnosis of idiopathic Parkinson's disease at any stage.

Not a fit: Patients with a history of aspiration pneumonia, severe swallowing difficulties, or other neurological disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve swallowing function and reduce drooling in patients with Parkinson's disease.

How similar studies have performed: While there have been studies on digital therapeutics for various conditions, this specific approach using a wearable sensor for dysphagia in Parkinson's is relatively novel.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion criteria. Age ≥22. English speaking. Diagnosis of idiopathic Parkinson's disease of any Hoehn and Yahr stage (I-V), determined by a neurologist.

Mild to moderate sialorrhea defined as a score of ≥ 11\* on the Radboud Oral Motor Inventory for Parkinson's Disease (ROMP)-Saliva (C) subscale Subjects must be in the "on" phase of their medication during all study assessments. The "on" phase is defined as the period when the participant's medication is at peak effectiveness, minimizing motor fluctuations and enabling optimal motor function.

Study Exclusion Criteria. History of aspiration pneumonia within the past 12 months. Unable to swallow saliva without a maneuver. Actively receiving treatment for swallowing disorders or sialorrhea. Current alcohol/drug abuse. Diagnosed with neurological disorders other than PD. End stage dementia. History of head and neck cancer or surgery. Unable to demonstrate competency with the user-friendly sensor platform technology.

Known allergy to contrast material used during MBSS. Known allergy to sensor adhesive. Indwelling tracheostomy tube. Nasogastric (NG) feeding tube. Currently pregnant.
