Effect of Neurodynamic Mobilization of Vagus Nerve on Irritable Bowel Syndrome in Women

Effect of Neurodynamic Mobilization of Vagus Nerve on Irritable Bowel Syndrome in Women

goal of this interventional study to investigate the effect of neurodynamic mobilization of vagus nerve on irritable bowel syndrome in women. The main question it aims to answer is: is there an effect of neurodynamic mobilization of the vagus nerve on irritable bowel syndrome? The intervention will include neurodynamic mobilization of vagus nerve sessions ,Participants will receive the treatment for 6 week. Assessment will be done before and after treatment.

IBS is a chronic functional gastrointestinal disorder that profoundly affects patients' quality of life (QOL). Among the various symptoms, abdominal pain was the most commonly reported and often perceived as the most debilitating. Some patients, particularly mothers, even described it as more intense than labor pain. This pain led to a range of negative consequences, including impaired concentration, sleep disturbances, episodes of fainting, vomiting, physical immobility, inability to work, and feelings of depression .Neural mobilization promotes improved mobility and interaction between nerves and adjacent tissues (interfaces) through the application of manual techniques or specific exercises .Neurodynamic techniques targeting the vagus nerve have shown potential as an effective approach to promote parasympathetic nervous system activation. The application of vagus nerve neurodynamic techniques was associated with a significant reduction in mean heart rate (HR), suggesting a positive modulatory effect on parasympathetic nervous system activity .The potential therapeutic role of vagus nerve neurodynamic mobilization in managing IBS has not been extensively explored in the literature.

Therefore, this study aims to investigate the effectiveness of neurodynamic techniques targeting the vagus nerve in alleviating symptoms and improving quality of life in patients with IBS.

Inclusion Criteria:

• 32 Females with mild to moderate IBS ,were recruited for this study by referral from a physician.
• aged 20-45 (i.e., the most common age for developing IBS)
• Patients must experience abdominal pain recurring at least once weekly over the past three months.
• This pain must be linked to two or more of the following features: occurring in relation to defecation, accompanied by a change in stool frequency, or accompanied by a change in stool form or appearance.
• Symptoms should have been present during the last three months, with onset at least six months before diagnosis.

Exclusion Criteria:

Subjects will be excluded if they have:

• Organic gastrointestinal disorders.
• Thyroid abnormalities.
• Coexisting cardiovascular, respiratory, renal, or hepatic conditions.
• Pregnancy.
• Blood disorders. (e.g., hemophilia, coagulation disorders, leukemia, thalassemia, sickle cell disease).
• Neurological or musculoskeletal conditions affecting muscle tone.
• Psychiatric illnesses ( patients with depression in the absence of IBS).
• Fibromyalgia.
• A history of gastrointestinal surgery or resection, , or other chronic diseases associated with gastrointestinal issues such as inflammatory bowel disease, ulcers, or cancer.
• A history of alcohol or drug abuse, abdominal surgery within the past six months.
