Custom made dynamic ankle-foot orthosis (AFO)
©Thuasne®

Detailed description

SpryStep® AFO Custom is engineered to provide support and stability for individuals experiencing lower limb muscle weakness due to neurological, traumatic, or muscular origins. This orthosis is custom-fabricated from a digital scan of the patient’s leg, ensuring a precise and comfortable fit. The use of advanced composite materials guarantees both strength and lightness, which is crucial for prolonged use1 and patient compliance.

SpryStep® AFO Custom includes different versions to cater to specific needs:

  • SpryStep® Flex: Features a posterior-lateral, spiral strut with a posterior calf cuff, suitable for augmenting remaining dorsiflexor muscle powers in more active users.
  • SpryStep® Original: Incorporates a posterior-lateral strut with a posterior calf cuff, suitable for aiding flaccid dorsiflexor muscle powers.
  • SpryStep® Plus: Comes with a posterior-lateral strut and anterior shell, designed for aiding remaining plantarflexor and knee stability muscle power.
  • SpryStep® Max: Includes a lateral strut with a wide anterior shell, aiding weakened plantarflexors and knee stability muscle power for less dynamic users.
  • SpryStep® Vector: Customizable in shape and stiffness the SpryStep® Vector offers superior control for the most complex conditions and patients. 

Each model also includes a molded inner boot.

Specifications

  • These indications are biomechanical deficits of neurological, traumatic or muscular origin.
    Excessive plantarflexion during swing phase (secondary to weak dorsiflexors).
    Weakness of the pretibial muscles ≤ 3.
    Plantar flexor strength 0 to 4.
    Knee instability during stance phase.
    Quadriceps weakness.
    Knee hyperextension.
    Excessive knee flexion during stance phase (secondary to weak plantarflexors).
    Partial foot amputation (Chopart or more distal).
    Fatigueable footdrop.
    Footdrop.
    Foot slap.
    Circumduction.
