7. Insert the connecting rod in the fasteners and close the medial connecting rod fastener

8. The height of the knee joint pivot point is adjusted with the upper clip of the spring element

Settings up to max. 60 cm (knee gap to the ground) are possible

Pay attention to the positioning of the washers while closing the clamps

9. To adjust the a-p alignment of the rotation point, open the lateral clamps of the frame structure on the T-piece and slide the T-piece

Ensure that the closures of the strap on the lower leg are open so the T-piece can slide


| © Ottobock



10. Press together the lateral components of the frame structure to the extent that appears comfortable for the patient

11. Close the lateral clamps of the connecting rod and the T-piece

12. Check the knee joint pivot point and adjust if necessary


| © Ottobock



13. Ask the patient whether there are any uncomfortable pressure points

14. Check the M-L alignment and exterior rotation - adjust if required

15. Close the front closures of the straps first and then the rear ones

The Trial Tool is ready for testing!

1. Flex the Trial Tool at the knee joint by applying a forefoot load

2. Let the patient sit down on a chair3. Open the upper closures and straps4. Open the straps below the knee5. Open the straps on the shoe6. Pull the Trial Tool down and off to

remove7. Set the Trial Tool upright and fasten the

closures and straps8. Store the Trial Tool upright and charge if

necessary

Removing the Trial Tool – step by step

Calibrating the systemTwo possibilities:1. The patient stands with an extended

knee between parallel bars or with crutches

2. The patient sits on a chair with an extended knee and his leg resting on the heel

• There may not be any load on the spring or any movement in the knee joint!!!

Calibration is required each time a connection has been established

| © Ottobock



• Only walk within the parallel bars

• Only walk on level ground

• Don´t walk on ramps & stairs

• Don´t walk backwards

• Never let the patient walk unattended by a technician

Handling the Trial Tool with a patient

| © Ottobock

1. Set the Maximum Toe Load to the max. value to avoid stance release




| © Ottobock

2. For adjusting the STP Flexion Damping, the patient should sit down on a chair several times

• Both feet side by side • Distribution of the weight evenly on both

legs• The patient is either using the armrests or

the help of a therapist for support• The chair must have an appropriate height

The patient shouldn´t sit down too slow or too fast




| © Ottobock

3. Gaining trust in the STP Flexion Damping• The patient stands in a ´step forward

position´ in the parallel bar and bends the knee under load

With this exercise the patient is gaining trust in the C-Brace® -system within a short time and he/she is prepared for the first steps

Aim: The patient should perform the exercise with the minimum possible support of the therapist




| © Ottobock

4. Adjusting the Maximum Toe Load• Observe the toe load while the patient is

walking a few steps• Decrease the value untill the patient is

reliably triggering the swing phase

• The following criteria must be fulfilled:Toe load with simultaneous knee extension

The support of the arms should be reduced while practicing




| © Ottobock



5. Practicing the stance release while walking within the parallel bars

• Aim for a consistent gait velocity• Aim for an even distribution of the weight on

both legs• Check track width while walking

Pezziball-exercise:• Step position with the contralateral leg in the

front• Simulate toe load with an extended joint• Touch the ball with a kick movement of the

leg that is wearing the orthosis


| © Ottobock

To experience the benefits of the C-Brace® and clarify the differences to other existing systems the following functions can be demonstrated with the Trial Tool :

• Locked system LOM + Max Toe Load to the max.

• SCO LOM, Max Toe Load

• SSCO 1st mode

• Possibly activate STP Flexion Damping Plus for demonstration



Handling the Trial Tool with an able-bodied

| © Ottobock



Why can´t the patient use the Trial Tool properly?• Swing phase release isn´t working

Is the knee extended at the end of the STP? Is the Max Toe Load setting adjusted correctly?

• The patient is sinking into the system while walking Is he/she having a knee- or hip bending contraction? Possibly the STP Flexion Damping Plus can help & should be

tested

Troubleshooting

| © Ottobock



Main criteria:The patient must be able to reliably trigger the swing phase while walking on level ground!

• Is an upright position possible?

• Is the patient able to apply the product and remove it?

• Does the general physical constitution allow the treatment? (e.g. the patient isn´t totally exhausted after walking short distances)

• The Trial Tool test protocol can be used as a guideline and a support while testing a patient
