Dynamic carbon ankle-foot orthosis (AFO)
An overview of the family of lightweight carbon ankle-foot orthoses that store energy during walking and return it.
What is a dynamic carbon AFO?
An ankle-foot orthosis (AFO) is a type of orthosis used to contribute to walking by supporting the foot and ankle. Thanks to their lightweight and durable carbon-fiber structure, dynamic carbon AFOs are intended to store energy during the step and return this energy during the forward-movement phase.
These orthoses may be considered as a supportive part of the treatment plan in situations where loss of muscle strength or balance in the lower leg and foot affects walking. Suitability, choice of type and manner of use are determined solely by the physician's assessment.
How does it work?
Dynamic carbon AFOs work on the leaf-spring principle. When the heel contacts the ground, the carbon structure bends slightly and stores energy; as the foot leaves the ground, it returns this energy with the aim of supporting the forward phase of the step.
- Storing and returning energy during walking
- Contributing to the swing phase by limiting foot drop
- A lightweight carbon structure aimed at comfortable use inside the shoe
Key features
The features below are for general information; which design is suitable is determined according to the person's condition and the physician's assessment.
Lightweight structure
The carbon-fiber material aims to provide low weight while maintaining durability and is intended to make all-day use easier.
Energy return
Returning the energy stored during the step aims to support the forward phase of walking.
Slim profile
Slim design options aim to make use with most shoes easier.
Individual adaptation
The orthosis is selected according to the person's measurements and needs; the fit and settings are adjusted under specialist supervision.
Different design options
Dynamic carbon AFOs offer different levels of support and designs. The general groups below are examples; the choice is made by the physician.
Laterally supported design
Designs with a carbon structure running along the sides of the ankle that take into account the balance between swing and support.
Reactive support design
Designs focused on active use that aim for more pronounced energy return during the push-off phase of walking.
Foot-drop-focused design
Designs that support the front of the foot in situations where the foot does not lift sufficiently during swing.
Use in daily life
In people for whom it is deemed suitable, a dynamic carbon AFO may be used to support walking distance and confidence in daily activities. The aim is to contribute to a smoother gait and to help manage the risk of falling.
- Support for walking on level ground and gentle slopes
- A lightweight structure aimed at comfort during long-term use
- The duration of use and activities are determined on the physician's recommendation
The orthotic fitting process
Physician's Assessment
The fitting begins with a specialist physician's assessment and a prescription/medical report.
Measurement and Planning
Gait and the condition of the foot and ankle are assessed; the suitable type of AFO and the service plan are determined.
Fitting and Adjustment
The orthosis is fitted; the fit and settings are adjusted to the individual.
Follow-up
Training on use is given; follow-up is provided for check-ups and, when necessary, adaptations.
Frequently asked questions
Who is a dynamic carbon AFO suitable for?
Suitability varies according to the person's condition and is determined solely by the physician's assessment. It is generally considered in situations where loss of strength or balance in the lower leg or the foot and ankle affects walking.
Can I use the orthosis with shoes?
Slim-profile designs are intended for use with most shoes. Suitable shoes and the manner of use are recommended by the specialist.
How long should I use it?
The duration and manner of use are determined by the physician according to the person's condition; regular check-ups are recommended.
