Setting The Preflexion - Otto Bock AxonArm Hybrid 12K500 Instructions For Use Manual

Preparing the product for use

6.5 Setting the Preflexion

• The level of AFB compensation (flexion assistance) can be adjusted and adapted to the weight of different
clothing with the dial. Adjustments are easier to make when the forearm is flexed.
• The adjustment mechanism is protected by a slip coupling.
• The hydrodynamic damper of the flexion aid mechanism is designed to counterbalance the weight of the fore­
arm plus Axon-Bus gripping component. Please be sure to stabilise the upper arm component of the AxonArm
Ergo while testing the joint functions.
CAUTION
Lock released during donning, doffing or storing of the extended arm
Injury due to sudden bending of the forearm or the upper arm socket due to released lock.
► The Axon-Bus prosthethic system must always be flexed for donning and doffing.
► The Axon-Bus prosthethic system must be stored in flexed condition.

Region 1
Minimal compensation that allows natural free swing of
the arm while walking.
Region 2
Compensation increases progressively with flexion of
the arm and decreases during extension.
Region 3
Compensation remains constant. If set correctly, the
weight of the forearm is balanced by the compensation
and the elbow remains flexed.
Region 4
Reduced compensation until flexion stop.
