# Improve breathing with diaphragmatic stimulation

**Goal (in five words):** Improve breathing with diaphragmatic stimulation

**Official Title:** Investigation of the Effect of Spinal Mobilization and Respiration Techniques on Posture and Respiratory Function in Parkinson's Patients

**Trial ID:** [NCT04941326](https://clinicaltrials.gov/study/NCT04941326)

## Key Facts

- **Phase:** NA
- **Status:** RECRUITING
- **Study Type:** INTERVENTIONAL
- **Sponsor:** Abant Izzet Baysal University
- **Target Enrollment:** 63 participants
- **Start Date:** 2021-08-15
- **Completion Date:** 2025-12-01
- **Conditions:** Parkinson Disease, Camptocormia, Restrictive Lung Disease
- **Interventions:** Diaphragmatic stimulation treatment with PNF techniques, Costal mobilization, Breathing exercises, Spinal mobilization, Sham mobilization
- **Intervention Types:** OTHER

## Summary For Families

Aiming to ease the severe forward‑bending posture called camptocormia and boost breathing in people with Parkinson's who have restrictive lung signs. The program uses hands-on spinal and rib mobilization, diaphragmatic stimulation paired with PNF techniques that help retrain and activate the diaphragm, and targeted breathing exercises to increase chest wall mobility, improve diaphragm movement, and raise lung volumes; a sham mobilization group is used for comparison. Adults 50 to 85 with Parkinson's who volunteer and have a Modified Medical Research Council dyspnea score above 2 can join, while people with active COVID-19, recent chest or abdominal surgery, diaphragm mobility disorders, conditions that raise intra‑abdominal pressure, or chest masses are excluded.

## Eligibility

- **Minimum age:** 50 Years
- **Maximum age:** 85 Years
- **Sex:** ALL

### Full Criteria

```
Inclusion Criteria:

* Diseases that increase intra-abdominal pressure
* Diseases affecting diaphragmatic motility
* Those who had a recent thoracic or abdominal operation
* Those who have a parenchymal, pleural or chest wall mass that will cause restriction on a recent chest X-ray or CT will not be included in the study
