Thuasne SpryStep Plus Anterior Dynamic Ankle-Foot Orthosis

SpryStep^® Plus provides support and reassurance for individuals with biomechanical deficits of neurological, traumatic or muscular origin. Featuring an anterior carbon structure and a composite material blend, this orthosis ensures both strength and lightness. It supports the knee, particularly in flexion, aids plantar flexors for propulsion, and offers energy return during activities.

SpryStep^® Plus is designed to help individuals with foot drop syndrome, a condition that makes it difficult to lift the front part of the foot. 
This dynamic ankle-foot orthosis (AFO) support features an anterior composite structure that stabilizes the knee and guides it towards extension, particularly benefiting those with weakened plantar flexors by aiding in propulsion and maintaining knee stability during the stance phase.

Key benefits of the SpryStep^® Plus include:

• Strategic Stabilization: The composite structure of the SpryStep^® Plus offers a balance between flexibility and rigidity, improving walking efficiency and allowing the tibia to tilt during the stance phase.
• Enhanced Mobility: The unique posterior spiral strut design amplifies energy return, helping users move more efficiently.
• Durable Construction: Made from lightweight, durable composite materials with unique laminated characteristics to prevent delamination and breakage.
• Customizable Fit: The trimmable forefoot section ensures an anatomical adjustment allow to fit for various foot sizes and shapes.
• Patient Compliance: The orthosis's elegant design has been developed to provide both comfort and effective support, with the aim of enhancing patient compliance.
• Versatile Use: Suitable for a wide range of patients, from those with mild to pronounced gait abnormalities.

The SpryStep^® Plus is available in sizes XS to XL, fitting a broad spectrum of foot sizes. It is offered in both right and left versions to meet individual patient needs. Classified as a Class I medical device, it complies with all relevant regulatory standards.
