Key Features

The polycentric construction of the NOP5/NKP5 provides good stance stability, by means of its geometry, and a smooth pneumatically controlled swing phase, with independent adjustment of flexion and extension. The NOP5 is supplied with a male pyramid adapter to allow angular adjustments. The NKP5 comes with a laminating adapter, complete with adjustable alignment discs, making it particularly suitable for patients with very long residual limbs.
