at initial and terminal stance.

Features & Benefits...

  • Floor Reaction Design
    Dampens ground reaction force (GRF) for smoother and more efficient gait
    Redirects GRF at initial contact through forward progression
    Other designs possible
  • Adjustable Range of Motion
    Dorsiflexion and Plantarflexion range from 0-40º
  • Dual Adjustable Dynamic Response™ for Stance
    Adjustable response at initial contact and terminal stance
    A more biomechanically sound design allowing the ankle to move more while storing & releasing energy
    Adjustable dampening muscle compensation: Plantarflexion up to 600 in*lb,
    Dorsiflexion up to 600 in*lb
  • Prevents Toe Drag
    Returns ankle to neutral and assist foot clearance during swing
    Improve initial contact, stabilize ankle and advance the body during mid stance
  • Ground Reaction Force Transfer
    Dual medial & lateral stirrups support mid-foot and transfers GRF to toe lever


Indications: Gait training for stroke rehabilitation (forced limb use programs). Lower extremity weakness requiring a double action or floor reaction ankle-foot orthosis.
