Modular Engineered Carbon Spring System For Kids & Youths



The PDE™ Neuromuscular Kids is a modular engineered carbon spring system for composite & thermoplastic AFO brace designs. This simple, align-able system provides the ability to tune functional energy performance as the patient grows and changes. Dynamically adjust external, internal, plantar & dorsiflexion alignments as well as easily change spring stiffness.

PDE™ Kids springs are a perfect solution for:

• Smaller sized patients such as kids & youths.

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

• Nerve/muscle impairment below the knee.

• Deficit of dorsiflexion and/or plantarflexion.

• Common conditions such as: Guillain-Barre Syndrome, Spina Bifida, Spinal Cord Injury, Cerebral Palsy, Spasticity, & Heel Cord Tightness.

• Any patient who would benefit from:

• The tri-planar stability of a custom articulated AFO.

• The reliable control and ground reaction from a custom solid-ankle AFO.

• The energy return of a custom posterior leaf spring AFO.

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


Prevent drop-foot


Prevent falling


Stabilize gait


Reduce foot contractures


Improve ambulation through energy return


Improve quality of life


Adjustable Alignment

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

Alignment shims can be effortlessly inserted between the PDE spring and the brace to adjust the plantar/dorsi flexion and rotational alignment (in 2.5º increments) of both the upper-cuff & footplate individually.

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

Choosing The Right Spring Spring Length


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.

175mm & 225mm length springs

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

Choosing The Right Spring Spring Firmness (Category 1-7)



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 Pediatric Neuromuscular Brace.

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