What this trial studies

This interventional study applies noninvasive vagal stimulation using physiotherapy techniques (trigger point release and positional release) to pregnant women with newly diagnosed mild preeclampsia. Participants are outpatient women over 18 seen at IMSS hospitals in Guadalajara and must not have chronic hypertension or other major comorbidities. The intervention aims to activate the cholinergic anti‑inflammatory pathway via the vagus nerve to improve blood pressure control and placental blood flow. Safety, blood pressure, inflammatory markers, and pregnancy outcomes will be monitored during follow‑up.

Who should consider this trial

Good fit: Pregnant women over 18 with newly diagnosed mild preeclampsia who have not received prior treatment and can attend outpatient visits at the listed IMSS sites in Guadalajara.

Not a fit: Patients with severe preeclampsia, chronic hypertension, organ dysfunction, immunological disease, or gestational trophoblastic disease are excluded and unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the approach could lower maternal blood pressure and inflammation, reducing the risk of severe complications and improving outcomes for mother and baby.

How similar studies have performed: Preclinical models have shown promising blood pressure and inflammation effects from vagal stimulation, and some small clinical uses of vagal techniques exist, but rigorous clinical evidence specifically for preeclampsia is limited.
