7.4.5 Exercises and adjustments
Recommended sequence of the exercises and settings ( 21 – page: 12)
►
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 the annual
safety inspection.
Advise the patient to check the prosthesis if changes in function occur.
►
Observe the recommended sequence of the exercises and settings.
Sitting down (
22
– page: 13)
►
Practise sitting down with the patient.
Walking (
23
– page: 13)
►
Adjust all settings in small increments.
► Check the effect on the gait pattern after each change.
►
Adjust the settings first at normal walking speed, then with short, quick steps and finally with
long, fast steps.
►
CAUTION! Allow the patient to walk only with safeguards in place, as the prosthetic knee joint
may switch to swing phase flexion resistance too late with the factory settings.
If stance phase resistance cannot be activated at the beginning of the stance phase, decrease
the switching threshold in small increments until it can be activated even with different walking
speeds and stride lengths.
►
Adjust the swing phase flexion resistance so the lower leg of the prosthesis does not swing
through too far in the dorsal direction but reaches full extension in time for the next heel strike.
► Adjust the swing phase extension resistance so the prosthetic knee joint does not swing too
hard against the extension stop but reaches full extension in time for the next heel strike.
►
If necessary, install the additional supplied spring according to figure
24
on page: 14 to
enhance the extension assist function so the prosthetic knee joint reaches full extension at the
next heel strike.
Walking down ramps (
25
– page: 14)
►
Adjust the stance phase flexion resistance so it provides the patient with adequate safety yet
does not generate excessive resistance.
Walking down stairs (
26
– page: 15)
►
Adjust the stance phase flexion resistance so it provides the patient with adequate safety yet
does not generate excessive resistance.
Walking (repeat for readjustment) ( 27 – page: 15)
► Check the swing phase flexion resistance again and, if necessary, adjust it in small incre­
ments so the lower leg of the prosthesis does not swing through too far in the dorsal direction
and reaches full extension in time for the next heel strike.
Using the lock (
28
– page: 16)
►
Practise using the lock.
Cycling (
29
– page: 16)
►
If the patient wants to participate in cycling or similar sports, perform corresponding exercises
(e.g. on an exercise machine) with them. The lock must be deactivated for these sports.
