Ear stimulation for constipation in Parkinson's disease
Part of Brain & nervous system clinical trials.
This trial tests whether a gentle electrical stimulation applied to the ear (called transcutaneous auricular vagus nerve stimulation, or taVNS) can help relieve constipation in people with Parkinson's disease. The study aims to see if this non-invasive treatment can improve bowel movement frequency and quality of life.
Summary written for real people, not researchers, by Clin2.

This trial tests whether acupuncture can help relieve constipation in people with Parkinson's disease. If you have both Parkinson's and constipation that is not caused by another medical condition, this study may offer a non-drug treatment option.
This trial tests whether a non-invasive nerve stimulation device (taVNS) worn on the ear can protect brain cells and slow Parkinson's disease progression in early-stage patients. It is for people who have been diagnosed within the last 3 years and are already on standard medication.
This study tests a method of cleaning the lower bowel with water (transanal irrigation) to see if it improves constipation in people with Parkinson's disease. It may help with bowel symptoms and possibly affect gut health.
This study tests whether mild electrical stimulation on the ear (called taVNS) can help people with difficult-to-treat constipation. It aims to find the best stimulation schedule to improve bowel movements.
This study tests a gentle stimulation of the vagus nerve (a nerve that helps the gut work) using a small device on the ear, for people with IBS-C. The goal is to see if this can improve constipation and other IBS symptoms without drugs.
This study tests a gentle, non-invasive ear stimulation device (like a small earpiece) that may help improve depression symptoms in people with Parkinson's disease. It uses a nerve in your ear that connects to the brain, and the goal is to see if it can safely boost your mood without medicine.
