The instructions in this section are for practitioner use only.
Adjust the Cushion Valve prior to commencement of programming.
For increased damping of terminal impact, rotate the valve clockwise (2.5 A/F Wrench Key).
Adjust the cushion resistance whilst the amputee is walking slowly.
At this speed the damping level should be set
to the highest resistance that still permits the
knee to extend fully and remain extended during
the entire stance phase. This should result in the
elimination of terminal impact at higher speeds.
Fine tune settings as the trial progresses, always
confirming that the limb fully extends during slow
walking.
Note… Typical increments are 1/4 turn until valve
has effect thereafter smaller increments should be
used to optimize terminal impact.
