Application

The following buttons/connections are found on the hydraulic unit

2.2 Function

The orthotic system features a microprocessor-controlled stance and swing phase.
Based on the measurements of an integrated sensor system, the microprocessor controls hydraulics that influence
the damping (resistive movement) behaviour of the knee joint. The sensor data are updated and evaluated 50 times
per second. This adapts the behaviour of the orthosis to the current movement situation (gait phase) dynamically
and in real time.
Thanks to the microprocessor-controlled stance and swing phase, the system can be individually adapted to the
needs of the patient. In order to do so, the system is adjusted by the Orthotist using special software.
The orthotic system offers a 2nd mode for individual movement patterns (e.g. cycling, cross-country skiing etc.).
This is preconfigured via a software programme and can be accessed by the patient by means of buttons located
on the front of the hydraulic unit.
The so-called LOM (Lock Orthosis Mode) can also be selected. Stance phase damping is especially strong in this
mode, offering a certain level of security for new patients in particular. The swing phase can be triggered notwith­
standing high stance phase damping.
Empty battery mode, in which the orthosis switches to a predefined stance phase damping value, permits safe
walking when the battery is drained.
3 Application

3.1 Medical Purpose

The orthosis is intended solely for orthotic fittings of the lower limbs.

3.2 Indications

Unilateral lower limb paresis or flaccid paralysis, e.g. due to polio, traumatic paresis including paraplegia.
Physical prerequisites such as muscle status, mobility grade and axis deviations that guarantee proper control of
the orthosis are crucial.
The patient must fulfil the physical and mental requirements for the perception of audible signals.
Indications must be determined by the physician.

3.3 Contraindications

• Flexion contracture in the knee joint in excess of 10°
• Varus malposition in excess of 0° or valgus malposition in excess of 10°
• Ankle arthrodesis: passive range of motion less than 2°

3.4 Required Qualifications

3.4.1 Orthotist / Prosthetist Qualifications

Fitting a patient with the orthosis may only be carried out by Orthotists who have been authorised by Ottobock after
completion of a corresponding training course.
Participation in Ottobock product training for the orthotic system is mandatory prior to using the C-Soft adjustment
software. Additional product training may be required to obtain qualifications for product updates.
