# Improve swallowing safety and function

**Goal (in five words):** Improve swallowing safety and function

**Official Title:** Clinical Efficacy and Mechanism of tDCS for Dysphagia in Patients With Parkinson's Disease

**Trial ID:** [NCT07153692](https://clinicaltrials.gov/study/NCT07153692)

## Key Facts

- **Phase:** NA
- **Status:** RECRUITING
- **Study Type:** INTERVENTIONAL
- **Sponsor:** Wang Ping
- **Target Enrollment:** 58 participants
- **Start Date:** 2025-07-17
- **Completion Date:** 2029-12-31
- **Conditions:** Parkinson's Disease and Parkinsonism, Dysphagia
- **Interventions:** tDCS, Conventional Dysphagia Treatment, sham tDCS
- **Intervention Types:** DEVICE, BEHAVIORAL

## Summary For Families

The goal is to improve swallowing safety and function in people with Parkinson's disease or related disorders, lowering the risk of choking and aspiration. The approach uses transcranial direct current stimulation, a low, noninvasive electrical current applied over the brain areas that control swallowing to boost cortical excitability and plasticity, given alongside standard dysphagia therapy and compared with a sham stimulation. They are looking for adults 18 to 100 with VFSS-confirmed dysphagia and a diagnosis of Parkinson's, MSA, or PSP, who are cognitively intact (MMSE >23), can consent and cooperate, and do not have other causes of dysphagia, active pneumonia, severe organ failure, or metal implants.

## Eligibility

- **Minimum age:** 18 Years
- **Maximum age:** 100 Years
- **Sex:** ALL

### Full Criteria

```
Inclusion Criteria:

* Meet the Chinese Diagnostic Criteria for Parkinson's Disease (2016) or MDS Diagnostic Criteria for Multiple System Atrophy or Progressive Supranuclear Palsy;
* VFSS examination indicates dysphagia;
* Mini-Mental State Examination (MMSE) score \>23;
* Willing to cooperate with the study and sign the informed consent form;

Exclusion Criteria:

* Comorbid with other diseases that cause dysphagia;
* Comorbid with pneumonia, or severe cardiac/renal insufficiency;
