9.6 OPG function (Optimised Physiological Gait)
INFORMATION
The "PreFlex" function can be activated/deactivated using the adjustment software.
All other parameters of the OPG function are always active and cannot be influenced.
The OPG function minimises the prosthesis wearer's prosthetic deviations from a harmonious gait pattern and pro­
motes more biomechanically correct walking. This function enables the following features:
PreFlex
PreFlex ensures the knee is in 4° of flexion at the end of swing phase in preparation for loading response. This
makes initiating stance phase flexion easier and forward movement is less restricted.
Adaptive yielding control
The knee joint has auto-adaptive stance and swing extension resistance. The stance flexion resistance experienced
by the user is dependent on the slope or incline when walking downhill. When walking on a ramp, adaptive yielding
control manages flexion depending on the angle of the ramp. The knee joint flexes slowly if the ramp is flat, and
flexes quickly if the ramp is steep.
Dynamic stability control (DSC)
DSC ensures the knee will not release stance resistance during biomechanically unstable static and dynamic con­
ditions. 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, multi-directional movement and
walking backward are also possible without risk of stance resistance releasing.
Adaptive swing phase control
Instantaneous adaptation to varied walking cadences and to changes of the pendular mass (e.g. varying footgear)
ensures the knee always achieves the swing flexion target angle within (+/-) one degree. The swing phase exten­
sion and flexion resistance experienced by the user are auto-adaptive.
The flexed and partially loaded knee will also disable the stance phase on slopes and ramps to allow for greater
knee flexion and more ground clearance in the swing phase.
10 MyModes
In addition to basic mode (mode 1), up to 5 MyModes can be activated and configured with the adjustment soft­
ware. They can be called up by the patient using the Cockpit app. Only the first 3 MyModes can be selected using
movement patterns. Switching by using movement patterns has to be activated in the adjustment software.
These modes are intended for specific motion patterns or postures (e.g. inline skating, running (jogging) ...).
Default settings for these motion patterns and postures can be called up and individually adapted using the adjust­
ment software.
Settings can also be adjusted by the patient using the Cockpit app (see Page 95).
Only when "DUAL" marking is not present ( see Page 66 )
For information on switching MyModes with the remote control (optional accessory), see the remote control
instructions for use.
