Nexgear Tango ankle joint

For patients with leg muscle paralysis, this dynamic ankle joint for leg orthoses enables smoother walking—on level surfaces, inclines, or stairs.

Four modules—Stop, Spring, Reaction, and Ultra—can be added or removed, allowing the joint to be individually adapted to the patient’s needs throughout the rehabilitation process. The Reaction and Ultra modules provide energy return at varying levels while maintaining maximum freedom of ankle movement. They dynamically control and support plantar flexion and lifting, normalize knee loading during the stance phase, and assist with toe-off and initiation of the swing phase.

Static and dynamic adjustments are performed separately. Dynamic adjustment is achieved through continuously variable pretension of the Reaction springs, and the joint maintains a 20° range of motion for both dorsiflexion and plantar flexion.

The joint is suitable for both children and adults, with the appropriate module selected according to body weight. It can be used for both unilateral and bilateral treatment.
