Adjustable. Alignable. Reusable. A Modular System

The PDE™ Neuromuscular Adult is a modular engineered carbon spring system designed for composite and thermoplastic AFO brace designs. This align-able system allows for tuning of functional energy performance as the patient grows and changes. It enables dynamic adjustments of external, internal, plantar, and dorsiflexion alignments, and allows for easy changes to spring stiffness.


A Perfect Solution For:

• Any patient who would benefit from a custom posterior leaf spring AFO where pain and offloading of weight are not a key factor.

• Patients with moderate muscle weakness who would benefit from Dorsiflexion & Plantarflexion assistance.

Features & Benefits

  • Modular, Reusable Design
  • 5 Flex Spring Choices
  • Low Profile
  • Reliable
  • Adjustable Alignment
  • Clinically Proven
  • Made in the USA

COST-EFFECTIVE. BALANCED. PDE™ Neuromuscular Technology Delivers:

We Made it Simple! Build Your Own Brace

Fabricating a brace using PDE spring technology involves industry-standard methods used for composite and thermoplastic brace fabrication. If you are versed in fabricating laminated and plastic prosthetics or orthotic devices, then you can make a PDE Neuro Brace. Design your own brace, do what is best for the patient. There are only a few rules to follow.

PDE springs are sold in kit form so you can provide your own unique brace designs with engineered consistent results.

Our partners will be happy to help.

We have partnered with two Central Fabrication companies who meet our high quality standards. (*We currently only offer central fabrication services for our Reaktiv™ brand braces. Learn more about Reaktiv™)

CHOOSING THE RIGHT SPRING Basic Guidelines for Choosing PDE Spring Length & Stiffness


Because every patient has unique needs there are no specific weight limitations that aid in spring choice. Choose the category based on your patient assessment. As a general rule you want to use the longest spring system your cuff design or patient height will allow. In an Orthopedic case where you are trying to control and limit motion to control pain, we recommend using a higher category spring in the beginning.

200mm & 250mm length springs

A common length to fit a wide variety of patients. Easily adjust and tune to the appropriate spring flex category to provide maximum function and energy return.



Category number three (3) spring is a good starting point. From here the AFO can be tuned Firmer or Softer based on the patient needs. The simple four-bolt system makes changing the spring quick and easy

Alignment shim set

Shim Kit
The PDE modular system allows for fine-tuning the alignment during patient fitting, delivery, and follow-up;a To improve the function, performance and comfort of the AFO brace.

Shims can be changed and adjusted at any time during the life of the brace, making it easy to adapt to patient changes.

Recommendation: PDE Fitting Kit

Get it right. Get the Fit Kit.

The Fitting Kit is an in-house diagnostic tool which includes the most common range of spring categories (1-5) and assembly components to build the initial brace. It also allows for fine-tuning adjustments during patient fitting & delivery.  

Fit Kit Contents: 5 PDE Springs (One each PDE spring category 1 through 5), mounting anchor kit, alignment shim kit, adhesive dispenser and adhesive.
