A mechanical truth behind chronic pelvic instability and one-sided containment.

Created by Rachel Maria Kisellus

📘 Definition:

The Pelvic Shear Principle explains how stabilizing only one hip at a time creates asymmetrical pressure across the pelvis, leading to mechanical shear forces that travel through the sacrum, SI joints, and spine.

It highlights why bilateral femoral seating is essential ~ not for strength, but for load balance and joint integrity.

🔑 Quick Teaching Summary:

If one leg’s grounded and the other’s floating, your pelvis starts to twist. That twist creates shear ~ like sliding two pieces of paper across each other. The goal isn’t to force both sides into symmetry. It’s to seat both femurs so your pelvis stops warping under pressure.

🧭 Cueing Protocol: Pelvic Shear Reset

This is a standing or seated sequence designed to neutralize pelvic shear and invite bilateral femoral containment.

1. Anchor Both Heels

• Stand or sit with both feet on the floor.
• Gently press both heels downward as if rooting into soft soil.
• Feel for equal pressure ~ not force, just contact.

Cue: “Feel your legs plugging into the ground like anchors.”

1. Femoral Coiling: Bilateral Call-In

• Visualize each femur spiraling backward and inward into its socket.
• Start with one side (often the harder one), then invite the second side to meet it.
• Use an exhale to activate gentle glute tone, just enough to feel secure.

Cue: “Imagine both thigh bones hugging in like they’re twisting light bulbs into a steady socket.”
