This joint can be used in the fabrication of custom ankle orthoses to address gait deviation, muscle and joint weakness, and instability, increasing mobility. These orthoses are considered definitive and are not designed for stretching. Designed for pediatric/adolescent patients up to 110 lbs.
Ordering Information: Comes individually, specify left or right. Use two joints per ankle for patients weighing more than 50 lbs. The left joint can be used for the lateral side of left ankle or the medial side of the right ankle. The right joint can be used for the lateral side of the right ankle or the medial side of the left ankle. For a patient weighing less than 50 lbs the left joint would be used for the lateral side of the left ankle and the right joint would be used for the lateral side of the right ankle. In that case Ultraflex recommends using a companion ROM joint item AFOP-ROM for the medial side of the brace.
Adjustable muscle augmentation: ADR elastomer technology fine-tunes first, second and third rockers. Compression of the posterior channel augments the tibialis anterior in early to mid stance.
- Compression of the anterior channel augments the gastroc-soleus in mid to late stance. Changing the restraint level is accomplished with simple set screw adjustments. Orthotists can make further refinements as dictated by patient presentation by adjusting elastomer length.
- Unrestricted motion: Ultraflex ADR restrains range of motion, but does not hold it or stop it, offering increased ROM stability. The plantarflexion or dorsiflexion stop can be used to create a rigid stop when dynamic restraint is not adequate.
- Customized stability in stance: ADR selectively augments and provides support for the tibialis anterior and gastroc-soleous muscles and alters their response to ground reaction forces (GRF) as needed; 0-140 inches/lb of torque restraint for plantarflexion and dorsiflexion. Dual medial and lateral stirrups support the mid-foot and transfer GRF to the toe lever. The custom interface provides support specific to the patient presentation.
- Smooth/natural roll-over: adjustable range of motion, plantarflexion and dorisflexion range from 0-40º; ADR allows for improved knee-ankle-foot biomechanics with stabilized ROM. ADR may maximize speed at a reduced energy cost.
- Clearance in swing: ADR provides sufficient force to restrain GRF, returns the ankle to neutral, and assists foot clearance during swing.
