The optimisation method can be used as an optional second step.
With the 743L100 L.A.S.A.R. Posture, optimisation is possible only based on the values of the
optimisation method .

(Page: 7): : Optimisation with 3D mode activated
►
Optimise the static alignment so the patient stands in a relaxed position, the values for the ref­
erence points shown in the illustration are met and the following points are observed:
• : 3D mode is activated (3D symbol – colour: light grey).
- Sequence for optimisation in reference to the planes:
1.1
: Sagittal plane –
1.2
: Frontal plane
• : The prosthetic knee joint is in extension. The lock, if present, is activated.
• : The reference line lies on the sagittal reference point of the prosthetic knee joint (pivot
point).
• : The reference points are in the centre (50 : 50: pyramids of the prosthetic knee joint and
the prosthetic foot, shoes).
• : The extension of the reference line points to the reference point (anterior superior iliac
spine).
• : The reference line lies on the frontal reference point of the prosthetic knee joint (pyramid).

7.4 Optimising during dynamic fitting
7.4.1 Notices regarding dynamic fitting
CAUTION
Adjusting the Settings
Fall due to incorrect or unfamiliar settings
► Only adapt the settings to the patient gradually.
►
Explain the effects of the adjustments on the use of the prosthesis to the patient.
7.4.2 Overview of adjustment possibilities
Stance phase flexion resistance (

– page: 8 – )
: Adjustment range; : Decrease stance phase flexion resistance; : Increase stance phase
flexion resistance
Switching threshold (

– page: 8 – )
: Adjustment range; : Decrease switching threshold (lower weight required to initiate the
stance phase); : Increase switching threshold (higher weight required to initiate the stance
phase)
