Walking the Patient and Adjusting the Shock
Step 1.
Set the shock to the zero set point.
Set the Blue Lever to the 10 O’ Clock position.
Turn the Red Dial in a clockwise rotation until it stops.
Remove all the air from the shock.
Remove air cap and depress the valve with a tool.
Step 2.
Set shock to “Recommended Home Position.”
This is your starting position for each change in air pres-
sure.
Blue Lever set to the 10 O’ Clock position.
Turn Red Dial (4) clicks counter clockwise. The black notch should be at the 7 O’ Clock posi-
tion.
Add 10 psi to the shock using the supplied shock pump.
Step 3.
With the knee set at “Home Position” have the patient walk a few times in the parallel bars.
They should feel a slight resistance in the shock. This is a good starting point for ambulation
tuning.
The first adjustment to address is extension. Adjust the red dial either COUNTER-
CLOCKWISE (faster extension) or CLOCKWISE (slower extension) from the original 7 O’clock
home position. Find the desired extension speed of the knee while walking the patient in the
parallel bars. Move the dial one click at a time faster or slower as it may only take one click
either way to find the desired settings.
The second adjustment should be to flexion by adjusting the Blue Lever into one of three posi-
tion options on the shock.
The patient should be at an air pressure range that they can walk with while the Blue Lever is
in the 10 O’clock position. (labeled as “Unlock”
on the shock)
Warning! If the patient is not stable they can fall at this stage of the fitting.
Note: Keep notes on settings while working through adjustments.
