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 left outer tricep comfort and extension through targeted lateral brachial nerve pathway and posterior shoulder approaches.
Placement Protocol al4.3.1
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 left outer tricep comfort support

1. Primary Placement

Location: Left Outer Tricep

Purpose: Targets local lateral brachial nerve pathways, outer tricep muscle fibers, and posterior shoulder girdle attachments for direct arm extension comfort and stability.

Positioning Guide: Position the PFE25™ array over the left outer tricep muscle, on the lateral (outside) portion of the back of the upper arm between the shoulder and elbow. Focus on the outer aspect that faces away from the torso. 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: Left C7 (cervical vertebra)

Purpose: Interrupts nerve compression signals at C7 nerve root level, targeting brachial plexus pathways that supply the lateral posterior arm and outer tricep region.

Positioning Guide: Position the PFE25™ array on the left side of the neck at the C7 level, at the base of the neck where it meets the shoulder. This targets the C7 nerve root which is a key contributor to lateral brachial plexus and outer tricep muscle innervation.

3. Tertiary Placement

Location: T3 Center (thoracic vertebra)

Purpose: Resets central nervous system coordination for upper thoracic sympathetic regulation and posterior shoulder postural optimization.

Positioning Guide: Position the PFE25™ array at the T3 vertebra level on the spine, approximately at the upper portion of the shoulder blade region. This central placement provides upper thoracic sympathetic regulation focused on extension mechanics and enhances posterior arm coordination.

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.
