Pneumatic fine-tuning
Step
Condition
1.
Flexion movement
too big
Flexion movement
too small
2.
Extension resistance
too weak
Extension resistance
too strong
Attention!
Covering the leg prosthesis with a foam cosmetic may require
further adjustment of the pneumatic settings. For example,
the tension in a flexed cosmetic foam cover may increase the
extension force and thus make further resistance adjustment
necessary.
Attention!
Never tighten the valve screws completely, as the valves may
become damaged during movement!
Attention!
Never increase the extension resistance far enough so full
extension of the joint is impossible. Loading a flexed knee joint
with body weight will definitely cause the patient to fall!
