The NEURO CLASSIC-SWING system ankle provides motion control, an increased dorsiflexion-assist as well as a dynamic and adjustable plantar flexion stop. The range of motion in plantar flexion can be adjusted. The range of motion in dorsiflexion can also be adjusted by filing the system stirrup.

The spring force can be changed by exchanging the spring units. Those enable a controlled, dynamic plantar flexion, control the tibial progression and affect the knee flexion during loading response.

Furthermore, the NEURO CLASSIC-SWING system ankle joint can be converted into a NEURO SWING system ankle joint by exchanging the cover plate and filing the system stirrup.
