Anatomical Focus of This PFE25™ Protocol

The three thumbnails below display the PFE25™ placements for this protocol. At present, this is the only protocol available for this anatomic area.

Supports sacral notch comfort and lower back wellness through targeted sacroiliac joint and posterior nervous system approaches.
Placement Protocol tsb16.3.1
This protocol is designed for use with three PFE25™ units at the same time.

This image shows three PFE25™ units being used simultaneously, following the placement instructions outlined in this protocol.
PFE25™ wellness placement overview for sacral notch comfort support

1. Primary Placement

Location: Sacral Notch

Purpose: Supports local sacroiliac joint mechanics and posterior superior iliac spine comfort for direct sacral notch stability.

Positioning Guide: Position the PFE25™ array over the sacral notch area, located at the posterior superior iliac spine region where the sacrum meets the iliac bone. This placement targets the sacroiliac joint nerve pathways and addresses local posterior tension. The array can be placed on the skin or up to 1 inch away, and works effectively through clothing and other non-magnetic materials.

2. Secondary Placement

Location: L5 Center (fifth lumbar vertebra)

Purpose: Supports nerve pathway wellness by targeting L5 nerve root pathways that contribute to sacroiliac joint function and sacral stability.

Positioning Guide: Position the PFE25™ array at the L5 vertebral level in the center of the lower back, approximately at the level of the top of the hip bones. This placement addresses lumbar-sacral nervous system coordination and supports the nerve pathways that connect to the sacroiliac region for optimal wellness integration.

3. Tertiary Placement

Location: T5 Center (fifth thoracic vertebra)

Purpose: Supports central nervous system coordination for mid-thoracic sympathetic regulation and postural chain optimization from thoracic to sacral regions.

Positioning Guide: Position the PFE25™ array at the T5 vertebral level in the center of the mid-back, approximately level with the middle of the shoulder blades. This placement provides central nervous system balance and postural chain coordination to support comprehensive sacroiliac and sacral notch wellness integration.

Placement Guidance

The placement guidance above illustrates three PFE25™ positions associated with the anatomical area shown in the image at the top of this page. In each placement protocol, three PFE25™ arrays are intended to be used together in the positions shown.

Because every individual is different, you may find it helpful to experiment with slight adjustments to discover what feels most effective for you. In many cases, the primary placement is positioned directly over the anatomical area of focus, but this may vary since the body is a complex network of nerves and muscles.

The placement images show the PFE25™ array by itself, but it may also be used inside a small pillow, a waist pack, or with other products that do not interfere with magnetic fields.
