In this guide, I'll walk you through a safe, practical way to address the mechanical cause of Acid Reflux, GERD, and hiatal hernia using the Reflux Shield — a self-help device I developed to mimic the clinician's hiatal reduction maneuver in the comfort of your home. This post covers rib-cage differences, when to use an angled technique, a step-by-step how-to, safety tips, and a brief look at supporting clinical evidence for manual approaches to hiatal hernia and reflux symptoms.
Why rib shape matters for Acid Reflux, GERD, hiatal hernia correction
People don't all have the same rib-cage geometry. Some have a broad, relatively flat sternum and a long or wide xiphoid area; others (the majority) have ribs that angle upward and inward toward a pointed xiphoid — almost like a teepee. That angle changes how you position the Reflux Shield so the applicator can get beneath the rib margin, engage the top of the stomach (the herniation) and scoop it downward.
If your ribs meet sharply at a point (a pronounced xiphoid process), start the device at an angle along the ribs. If your chest is wider and the xiphoid is flat and broad, you start with the device horizontal in the midline and slide down without an angular twist.
The Reflux Shield — how it works (simple mechanics)
The Reflux Shield is designed to reproduce the clinician's manual hiatal reduction: place a broad surface under the ribs, engage the stomach, and pull/scoop the herniated stomach back below the diaphragm. Two key principles make the maneuver effective:
Key safety tips and practical notes
- Use lotion or a light moisturizer if skin is dry — avoid Vaseline unless you don't mind staining clothing. Lotion helps the applicator glide.
- Watch for pulsation. If you feel a strong pulse under the device, reduce pressure immediately — that’s the abdominal aorta.
- Work within comfort. It can take a minute or two to build the right pressure. Slowly progress through the park → neutral → drive sequence instead of rushing.
- Lighten pressure near the belly button; that area is more sensitive.
- This technique is intended for sliding hiatal hernias and reflux due to mechanical displacement of the gastroesophageal junction, not for all abdominal complaints. Follow product instructions and clinical guidance.
What evidence supports manual approaches for hiatal hernia and reflux?
Manual osteopathic and manipulative techniques have been reported to reduce symptoms and, in case reports, even reduce a hiatal hernia without surgery. A documented case report described the resolution of a 3 cm hiatal hernia after four osteopathic manipulative treatment (OMT) sessions, with symptomatic improvement and objective findings showing restoration of normal anatomy. Systematic reviews and qualitative studies have explored manual therapy as a management approach for gastroesophageal reflux disease and have reported beneficial outcomes in some patients, particularly when manual care addresses somatic dysfunction that influences diaphragm and gastroesophageal junction mechanics.
Selected references worth reviewing include: a case report of hiatal hernia reduction with OMT (PMC article), qualitative evaluations of osteopathic manipulative therapy for GERD, literature reviews on osteopathic treatment for pregnancy-related discomforts (which touch on visceral mobilization concepts), and a systematic review of manual therapy for GERD. These sources support the biological plausibility that restoring normal rib, diaphragm, and visceral mechanics can reduce reflux symptoms in appropriate patients.
Who may benefit — and who should avoid this
Best candidates:
- People with reflux/GERD symptoms are linked to a sliding hiatal hernia or mechanical displacement of the gastroesophageal junction.
- Individuals whose rib cage forms an angled xiphoid or who can palpate the stomach edge under the rib margin.
When to avoid or seek medical clearance:
- Recent abdominal surgery, a known large paraesophageal hernia, or severe cardiopulmonary disease — consult a physician first.
- Significant persistent chest pain, unexplained weight loss, vomiting blood, or severe dysphagia — seek immediate medical evaluation.
Final thoughts
Addressing the mechanical component of Acid Reflux, GERD, hiatal hernia can offer symptom relief without immediately resorting to medications or surgery. The Reflux Shield and a clinician-taught technique can reproduce the manual maneuver safely at home when used properly. Pay attention to rib shape, start in the correct orientation (angled vs. horizontal), use the park→neutral→drive sequence, and apply only comfortable pressure while watching for pulsation and sensitivity near the belly button.

FAQ
How do I know whether to start the Reflux Shield at an angle or horizontally?
Trace your ribs inward with your fingers. If the ribs meet in a sharp point at the xiphoid (a teepee shape), start at an angle following the ribs and use the slight twist to flatten the applicator. If the xiphoid is broad or the ribs come up more horizontally, start with the device horizontal in the midline and slide straight down.
Is it safe to use the device myself at home?
When used correctly and within comfort limits, the device is designed for safe home use. Start slowly, use lotion to help it glide, never apply excessive force, and stop if you have already had Hiatal hernia surgery repair, (abdominal aorta) or severe pain. If you have major medical conditions or recent surgeries, get clinician approval first.
How long does it take to feel improvement?
Some people notice symptom relief immediately after a successful reduction, while others may require repeated sessions or concurrent manual therapy. Clinical reports show improvement over multiple OMT sessions in some cases, but individual results vary.
Are there scientific studies that support manual reduction of hiatal hernia or manual therapy for GERD?
Yes. Case reports have documented hiatal hernia reduction using osteopathic manipulative treatment with objective and symptomatic improvement. Systematic reviews and qualitative studies on manual therapy for GERD show promising results in select patients, suggesting further research is warranted to define best candidates and standardized protocols.
