Fascial Mobilization Along the Vagus Nerve and Its Effects on Acute Physiological Parameters in Obstructive Sleep Apnea

This randomized controlled trial was designed to investigate the effects of fascial mobilization along the course of the vagus nerve on acute physiological parameters in individuals with obstructive sleep apnea syndrome (OSAS). Patients diagnosed with moderate to severe OSAS by polysomnography at Mardin Training and Research Hospital Sleep Laboratory will be included in the study. Participants will be randomly assigned to mobilization or control groups. In the mobilization group, 16 minutes of manual fascial mobilization will be applied to fascial regions associated with the vagus nerve, starting from the occipitomastoid suture and extending through the cervical, thoracic, and abdominal regions. The control group will rest in the supine position for the same duration. Heart rate, systolic and diastolic blood pressure, and peripheral oxygen saturation (SpO₂) will be recorded before and after the intervention. This study is expected to demonstrate the effectiveness of fascial mobilization as a non-invasive, low-cost, and innovative approach in the treatment of OSAS, contributing to clinical practice.
