Changes in the Autonomous Nervous System and in the cranio-facial pain threshold after applying visceral manual therapy in patients with chronic migraine and functional gastrointestinal disorders.

Chronic migraine — experiencing headaches on 15 or more days per month — is a debilitating condition that affects millions of people. Interestingly, many people with chronic migraine also experience functional gut problems like irritable bowel syndrome, bloating, or acid reflux. The gut and brain are closely connected through the nervous system, raising the question of whether treating the digestive system might ease head pain. This study applies visceral manual therapy — specialised gentle massage and manipulation of the abdomen targeting the diaphragm and digestive organs — to patients with both chronic migraine and functional gastrointestinal disorders. Before and after treatment, researchers will measure changes in heart rate variability (a measure of nervous system balance), neck movement, and pain sensitivity at several points on the head and neck. You may be eligible if you have both a diagnosis of chronic migraine and functional gastrointestinal disorders (according to Rome IV criteria) and are between 18 and 65 years old. People with a history of cervical or gastric surgery, recent tumours, pregnancy, certain bowel diseases (like Crohn's or diverticulitis), neurological diseases, psychiatric illness, or those currently using certain migraine medications or beta-blockers are not eligible.
