PRAFO 654SKG (Dynamic Dorsi-Assist)

Dynamic Dorsiflexion Assist

654SKG - (DDA™) Features Overview

The sophisticated 654SKG DDA™ (Dynamic Dorsi-Assist) Orthosis is designed to dynamically stretch the gastrocnemius and soleus 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.
