• Drop Foot Stability System

  • CLINICAL INDICATION:  Neurologic conditions resulting in foot drop or loss of posterior lower leg muscle strength


    Carbon fiber ankle foot orthosis ( make this a link to description)
      - controls ankle joint dorsiflexion and load on the Achilles tendon

    Custom functional foot orthosis (one pair)
     - controls rearfoot pronation
     - patented “Richie ArchLock™” lateral offloads the medial-central band of the plantar fascia

    Carbon fiber footplate with toe rocker
     - diminishes dorsiflexion of the MTP’s and engagement of the windlass

    Traditional solid shell plastic AFO braces designed to treat drop foot provide support primarily during swing phase. (1-3)  A carbon fiber AFO brace with lateral strut can add an additional benefit of dynamic recoil during the third rocker to aid in push-off or propulsion.  (4-5)

    Clinical Indications
    In cases of foot drop caused by stroke or nerve injury, where there is no spasticity and the knee is stable, the Richie Dynamic Assist Brace would be recommended.  However, when there is some degree of posterior leg weakness or contracture as seen in Charcot Marie Tooth disease, the Richie AeroSpring Drop Foot Stability System can provide additional support and improved gait efficiency.

    Many neurologic conditions result in acquired foot deformity, so the addition of the custom balanced foot orthotic to the carbon fiber AFO allows this innovative Drop Foot Stability System to address all levels of the pathology.

    The lightweight dynamic features of the Richie AeroSpring Drop Foot Stability System allows the otherwise healthy patient to engage in walking or running for exercise.  Dynamic carbon fiber AFO devices have shown ability to improve push off while optimizing energy expenditure during walking. (6-8)  The possibility for participation in sport or exercise would not be possible with most bulky sold shell AFO devices, but is now feasible with a carbon fiber brace system.

    1. Severe instability of the knee.  Mild to moderate instability in the sagittal plane can be controlled with the Richie AeroSpring System
    2. Severe ankle joint contracture with equinus.   The Richie AeroSpring System incorporates a carbon fiber brace with footplate aligned at 90 degrees.   Some compensation can be achieved by incorporating a heel wedge to balance equinus.
