6.3 Optimising the static alignment
6.3.1 Checking the static alignment
►
To check the static alignment, position the patient on the measuring device as shown in
Fig.
26
on page 19.
6.3.2 Optimising the static alignment
► In the sagittal plane, check the course of the load line
1
relative to the alignment reference
point 2 and correct this as shown if needed (see Fig.
27
on page 19).
► In the frontal plane, check the course of the load line 1 relative to the marked points ( 2 pros­
thetic foot, 3 prosthetic knee joint, 4 Spina iliaca anterior superior) and correct if needed
(see Fig. 28 on page 20).
6.4 Optimising during dynamic trial fitting
6.4.1 Resetting to factory defaults
► Before performing the exercises in the sections that follow, reset settings that have been
changed to factory defaults according to Fig.
29 on page 20.
6.4.2 Practicing sitting down and standing up
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.
► The patient has to learn safe operation of the lock for all exercises (lock by loading at full
extension/unlock using the lock slide).
► CAUTION! With the patient, practice sitting down 1 and standing up 2 (see Fig.
30
on
page 21).
►
CAUTION! With the patient, practice standing up 3 with a highly flexed joint. While standing
up, it is necessary to wait until the joint moves to extension again.
6.4.3 Practicing walking
►
CAUTION!
Using parallel bars or a handrail
1
, practice walking
2
with the patient (see
Fig.
31
on page 22).
►
NOTICE!
Be sure to establish functional exterior foot rotation 3 .
► Check the exterior rotation 4 of the prosthetic knee joint.
► Check socket flexion
5
.
► Check socket adduction
6
.
►
During the dynamic trial fitting, check to see if the deviations listed in figure 32 on page 23
occur and correct them correspondingly:
• 1 The resistance to movement for extension during the swing phase is too large
•
2
During the extension in the swing phase, there is no resistance to movement, or there is
but it is too small
• 3 The resistance to movement for flexion during the swing phase is too large
• 4 The resistance to movement for flexion during the swing phase is too small
• 5 The resistance to movement for flexion during the swing phase is too large due to the
attached stops for flexion damping
• 6 The resistance to movement for flexion during the swing phase is too small due to the
detached stops for flexion damping
