Optimisation With 3D Mode Activated - Ottobock 743L500 3D L.A.S.A.R. Posture Instrucciones De Uso

5.6.1 Optimisation with 3D mode activated

INFORMATION
The illustrations that follow show load lines with 3D mode activated, with an incorrect course since it does not
correspond to the optimum course described in the previous section. Possible causes are listed, identifying what
may be wrong and therefore how the static alignment has to be optimised. The course of the load lines with 3D
mode deactivated is shown in addition.
Due to their fundamental importance for the illustrations in this section, the possible causes and solutions listed
below are identified according to their numbers.
Possible causes
1a) Improper bench alignment
2a) Static alignment with shoes not optimised
3a) No adjustment for different heel heights of different shoes
Possible solutions
1b) Ensure proper bench alignment
2b) Optimise static alignment with shoes (prosthetics: adjust plantar flexion)
3b) Adjust different heel heights of different shoes to one heel height using insoles (also take the contralateral
side into account)
