surfaces when PreFlex is present� PreFlex also allows users to ascend ramps in a more anatomically
correct way by reducing the need for users to vault over a fully extended knee�
(2) Adaptive Yielding Control
The knee has an intelligent, auto adaptive control of stance flexion (max 17°) and extension move-
ments, depending on the forces affecting the knee system� The varying stance flexion resistance
experienced by the user is e�g� dependent on the behavior of the user, the surface condition and the
angle of a slope or incline�
(3) Dynamic Stability Control (DSC)
DSC ensures the knee will not release stance resistance during biomechanically unstable static and
dynamic conditions� Constantly checking multiple parameters, DSC ensures the optimally timed
decision for the knee to safely switch from stance to swing� Because DSC is always monitoring
knee function, multidirectional movement and walking backward are also possible without risk of
stance resistance releasing�
(4) Stance Release on Ramps
Although flexed and partially loaded - the knee will release stance on hills and ramps to allow for
greater knee flexion, improved swing phase clearance, and less hip flexion force needed to bring
the shank into extension�
(5) Adaptive Swing Phase Control
Instantaneous adaptation to varied walking cadences and to changes of the pendular mass (i�g�
varying footgear) ensures the knee always achieves the swing flexion target angle within (+/-) one
degree� The swing extension and flexion resistance experienced by the user is autoadaptive�
Enabling the OPG function:
The OPG function can be activated by the prosthetist using the X-Soft configuration software� When
this function is activated, both stance phase extension and swing phase extension are adjusted auto-
matically� This means that the configurations in these areas are not necessary and the corresponding
slider bars in the Swing phase and Stance phase tabs of the adjustment software are deactivated�
Running function:
The knee joint detects a transition from walking to running in Basic mode, and reacts accordingly�
The knee automatically provides a larger swing flexion angle appropriate for running and zero preflex
angle for heel strike�
When in Basic mode, you have to initiate the running function actively� To initiate a running step it
is best to exaggerate the loading of the prosthesis for the first steps until a steady running state is
reached� This exaggeration triggers the running function� It takes a little training, until you can use
the Running function in Basic mode�
Additionally, there is a dedicated running mode available, that your prosthetist can configure as a
MyMode� In this mode, every step will be performed as a running step with larger swing angle and
no preflex�
The running function will work with specialized running feet such as the 1E90 Sprinter as well as
with prosthetic feet with axial compression such as the 1C61 Triton Vertical Shock� Feet without axial
compression are generally not suited for running�
For details on how to use the running mode in conjunction with you foot, contact your prosthetist�
