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 upper hamstring comfort and mobility through targeted sciatic nerve pathway and lumbosacral coordination approaches.
Placement Protocol ulr3.3.1
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 upper hamstring comfort support

1. Primary Placement

Location: Left Upper Hamstring

Purpose: Supports local hamstring muscle fiber wellness and sciatic nerve pathway comfort for direct posterior thigh wellness.

Positioning Guide: Position the PFE25™ array over the left upper hamstring region, approximately 4-6 inches below the ischial tuberosity (sit bone). The array can be placed on the skin or up to 1 inch away, and works effectively through clothing and other non-magnetic materials. This targets the biceps femoris muscle group and local sciatic nerve branches.

2. Secondary Placement

Location: L5 Center (lumbar spine)

Purpose: Supports nerve pathway wellness between upper hamstring and lumbar spine through L5 sciatic nerve root approaches.

Positioning Guide: Position the PFE25™ array at the L5 vertebra level on the lower back, approximately at the level of the top of the hip bones (iliac crests). This targets the sciatic nerve root origin that provides innervation to the hamstring muscle group, creating optimal pathway support for comprehensive posterior thigh wellness integration.

3. Tertiary Placement

Location: T4 Center (mid-thoracic spine)

Purpose: Supports central nervous system coordination for optimal upper hamstring wellness through mid-thoracic postural pathway approaches.

Positioning Guide: Position the PFE25™ array at the T4 vertebra level on the mid-back, approximately level with the bottom of the shoulder blades. This provides mid-thoracic postural regulation and spinal alignment coordination that supports the entire posterior chain function, enhancing overall hamstring 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.
