PRAFO 654SKG (Dynamic Dorsi-Assist)

Dynamic Dorsiflexion Assist

DDA™ Features Overview

The sophisticated DDA™ (Dynamic Dorsi-Assist) Orthosis is designed to dynamically stretch the gastroc muscles, offsetting equinus contracture. The use of a series of posterior articulations allows for a virtually unrestricted range of plantar or dorsiflexion. The DDA™ Orthosis also provides nearly unlimited inversion or eversion of the ankle/foot complex.
The DDA™ Orthosis incorporates two elastic straps attached to the distal foot section and proximal calf section. These straps can be adjusted to compensate and/or offset varus and valgus tendencies while maintaining constant dorsi-assistive force. The DDA™ Orthosis incorporates an important telescoping calf section feature that allows for shortening or lengthening of the soft tissue/musculature.  This feature can also be locked out, if applicable.

NOTE: The posterior ankle strap is shown inside theupright in the adjacent photo. When fitted properly, the strap is outside the posterior upright bar.

DDA APPLICATIONS

Immediate fit, early Intervention in acute or sub acute rehabilitation of the patient

  • CVA, TBI, SCI and Diabetic neuropathy
  • Facilitation of functional knee and ankle joint position through flexibility of the aluminium posterior upright structure
  • Allows for optimal dorsi/plantar flexion ankle positioning to provide adequate clearance during swing phase and knee stability in stance phase.

Post musculoskeletal injury of the foot and ankle

  • Post tendo achilles lengthening immobilisation
  • Post Botox or serial casting
  • Stable fractures of the foot and ankle
  • Tendon or ligamentous tear/rupture
