FUNCTIONS
INCLINES/DECLINES
• During ramp ascent, proprio foot ® gradually raises the toe of the prosthetic foot. Adaptation begins on
the second step and makes small changes until it reaches the gradient of the ramp. proprio foot
®
continuously adapts on every step.
»
Dorsiflexion of the foot during ramp ascent reduces socket pressure and strain on the ligaments.
• During the swing phase, proprio foot ® will raise the toe to provide additional ground clearance.
• It is not necessary to lead with a particular limb when ascending ramps.
• During ramp descent, proprio foot
®
lowers the toe of the prosthetic foot.
»
This helps to increase safety and gives better support during roll over of the prosthetic side.
note:
Steep inclines or declines (above 20°) may trigger stair response resulting in unexpected
ankle adaptation.
STAIRS
• During stair ascent, proprio foot
®
will raise the toe.
This will facilitate stair ambulation and improve gait
symmetry.
• When leading with the prosthetic side, proprio
foot ® will adapt to this position after the second
prosthetic step on the stairs.
note:
Pay attention to transitions from and to
stairs.
When proprio foot
®
is activated for the first time, the
default manufacturer settings will be enabled. In the
default manufacturer settings, the stair response is
preset to 4° dorsiflexion.
To change the stair response, press the following
sequence:
(Figure N)
• To change stair response from 4° to 6°, hold down
and press three times.
»
The system confirms with three beeps and vibrations.
• To disable the stair response, hold down and press three times.
»
The system confirms with a single beep and vibration.
• To enable a stair response of 4°, hold down and press three times.
»
The system confirms with two beeps and vibrations.
