The sophisticated DDA (Dynamic Dorsi-Assist) orthosis is designed to dynamically stretch the gastroc muscles, offsetting equinus contracturing. The use of a series of posterior articulations allows for a virtual unrestricted range of plantar or dorsiflexion. The DDA orthosis also provides nearly unlimited inversion of 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 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.
