5. Advanced Set-Up
Device indicator shows the setup progress (Table 2).
Ankle Alignment (without wearing prosthesis)
Ankle Alignment adjusts the angle of the ankle to allow optimal posture with shoes of various heel heights.
Note: The device must be fitted with suitable footwear before performing Ankle Alignment.
Note: Heel height adjustment range is 0-50 mm (2"). If heel height exceeds 50 mm, the device will emit an audio
signal and not adjust to height.
1. Fit the device with suitable footwear and ensure free ankle motion.
2. Place the device on a level surface; make sure device is fully-charged device turned ON.
3. Initiate Ankle Alignment by pressing the power button quickly twice successively or in the app.
4. The device will beep once confirming initiation, and the indicator will light up, showing the alignment progress
(Table 2).
5. The actuator will move the ankle into appropriate position.
6. If successful, the device will emit an ascending audio tone, and the indicator will flash white. If unsuccessful,
the indicator will flash yellow, showing process needs to be repeated.
Bench Alignment (Fig. 3)
Alignment Goal
Alignment reference line (B) should:
– pass through midpoint of socket at either the patellar tendon level or at the ischial tuberosity level (D).
– fall at the 1/3 mark on the inside of the foot cover.
Note: Prioritize knee alignment over foot alignment if there is a mismatch.
Alignment Instructions
1. Position the foot so that the alignment reference line (B) falls at the 1/3 mark on the inside of the foot
cover (with the foot cover and shoe on). Consider the external rotation of the foot.
2. Use the applicable adapters to connect either the socket or the knee to the foot and establish the correct knee
center height.
3. If using a prosthetic knee: Position knee according to knee alignment instructions
4. On the lateral side of the socket, make a first mark (alignment reference point) at the midpoint of the socket at
either patellar tendon level or the ischial tuberosity level (D). Make a second mark at the midpoint of the socket
distally (E). Draw a line through both marks.
5. Position the socket so the alignment reference line (B) goes through the alignment reference point (D).
6. Set the correct socket angles for flexion/extension and abduction/adduction.
7. If using a prosthetic knee: Use the applicable adapters to connect the socket to the prosthesis.
Static Alignment
– Make sure the patient stands with equal weight on both legs.
– Check for correct prosthesis length.
– Check internal / external rotation.
– Check for correct load on toe and heel.
Dynamic Alignment
Note: Alignment should aim to minimize medial-lateral motion during swing phase, as excessive side motion may
affect the initiation of dorsiflexion during swing phase.
The heel to toe action can be influenced by:
– Heel Stiffness
– Anterior-Posterior positioning of device
– Dorsi-Plantarflexion
– Shoe Characteristics
