8 Knee Adjustment
8.1 Flexion / Extension Adjustment
Extension Resistance Adjustment: (Figure above right)
Using a 2.5mm hex wrench, turn Extension adjustment screw:
Clockwise increases knee extension resistance.
Anti-clockwise reduces knee extension resistance.
Flexion Resistance Adjustment: (Figure above left)
Using a 2.5mm hex wrench, turn Flexion adjustment screw:
Clockwise increases knee flexion resistance.
Anti-clockwise reduces knee flexion resistance.
Swing Phase Pneumatic setting is pre-set from the factory. Extension or flexion
adjustment is only needed if the clinician finds the wearer shows a need for
higher or lower walking speeds.
Swing Phase Control Adjustment: It is advisable to adjust
flexion before extension
for optimum walking symmetry. If needed, please follow directions below.
Ensure full knee extension occurs before performing extension adjustment.
Use following procedure only if there is a need to adjust extension or flexion:
•1) Turn extension screw anti-clockwise to lowest resistance - then
•2) Turn the flexion screw clockwise to set to highest resistance
(Do not over tighten if screw has resistance, or bottoms out – damage may
occur and void warranty!)
•Incrementally loosen (anti-clockwise) the flexion screw to adjust heel lift;
•Incrementally tighten (clockwise) the extension screw to smoothly stop
extension.
