Optimising During Dynamic Trial Fitting - Ottobock 3R67 Instrucciones De Uso

► CAUTION! Use thread lock at the latest when finishing the prosthesis according to Figure
on page 5.
7.3 Optimising the static alignment
► To optimise the static alignment, position the patient on the measuring device.
► In the sagittal plane, check the course of the load line relative to the marked alignment refer­
ence point and correct this if needed (see Figure
► In the frontal plane, check the course of the load line relative to the marked points (prosthetic
foot, prosthetic knee joint, spina iliaca anterior superior) and correct if needed (see Figure
on page 7).

7.4 Optimising during dynamic trial 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.
Checking the factory settings (
► Prior to the dynamic trial fitting, restore the factory settings (see Figure
→ : Flexion damping –
→ : Extension damping –
► Optimise the prosthesis settings in the sequence according to this section.
Setting flexion damping (
► For setting flexion damping, see Figure
→ : Increase flexion damping
→ : Decrease flexion damping
► CAUTION! The lower leg of the prosthesis must not swing through too far in the dorsal direc­
tion at the beginning of the swing phase.
Set flexion damping so that the lower leg of the prosthesis swings through in the dorsal direc­
tion according to the patient's requirements, but reaches full extension in a timely manner for
the next heel strike.
Setting extension damping (
► For setting extension damping, see Figure
: Increase extension damping
→
: Decrease extension damping
→
► CAUTION! The prosthetic knee joint has to reach full extension before the heel strike, even at
a slow walking speed. Observe the information under the heading "Fine-tuning the settings".
► Adjust extension damping so that the prosthetic knee joint does not swing too hard against the
extension stop and so that the prosthetic foot swings through sufficiently according to the
needs of the patient.
Fine-tuning the settings
► CAUTION! If the settings cannot be fully adjusted to the comfort needs of the patient, the set­
tings must be established primarily based on safety aspects. The extension position has to be
reached with every step and at any walking speed.
► Adapt the settings of the prosthetic knee joint to the patient by means of fine-tuning and exer­
cises.
► Check the adjustment of the prosthesis settings during normal consultations and every
3 months during the safety inspection.
Advise the patient and guardian to have the prosthesis inspected if changes in function occur.
