Enhanced mobility and a natural gait pattern

• Secured stance phase – free swing-through phase
• Electronically controlled system knee joint
• Joint system for custom orthoses
• The E-MAG Active is also suitable for patients with no ankle functionality
• Smoother, more natural gait pattern
• Temporary release function (e.g. for riding a bicycle)

The E-MAG Active offers enhanced safety, stability and above all mobility for your patients. It was developed specifically for patients who, due to partial paralysis or a complete failure of the knee extensors, are unable to stabilise their knee joint without compensating measures.

The knee joint is often stabilised through hyperextension achieved by compensatory movement of the gluteal muscles (when the foot touches the ground, hip extension leads to knee extension). As a result, severe ligament instabilities and arthrotic symptoms in the knee joint will develop over time.

The complete leg orthosis with integrated E-MAG Active can help counteract these unphysiological movements. It provides secure functionality for your patients, enabling them to walk with a largely normal gait pattern.

There are many therapeutic benefits for paralysis patients: Joint damage caused by contractures and immobilisation is prevented and muscle atrophy is reduced. Cardiovascular ability is retained for everyday activities. In case of disorders affecting the central nervous system, the assumption of functions by unaffected brain areas (motor relearning, cortical reorganization) can also be promoted. Thus the orthosis promotes the social and professional (re)integration of your patients.

A fitting with a stance phase-controlled complete leg orthosis that includes the E-MAG Active as an integrated component is indicated for paresis and paralysis of muscles and muscle groups of the lower extremities and in case of:

1. Pronounced deviations in the frontal and sagittal plane (knee and ankle)
2. A severely atrophic, bony leg with little soft tissue coverage
3. A severely shortened leg (more than 5 cm)
4. Patients that require a dorsal stop in the ankle in order to reach knee joint extension
5. Patients suffering from ankle stiffness
6. Patients that require a pronounced dorsiflexion function

Safe use of the E-MAG Active knee joint system requires certain residual muscle functions or hyperextension of the knee joint. This guarantees consistent activation of the swing-through and stance phases. While the knee joint system is controlled unilaterally, it always has to be equipped with a medial support.

The E-MAG Active is suitable for a body weight of up to 85 kg. Your patients do not have to have existing ankle functionality. Use of the E-MAG Active is also possible in cases of leg length reductions or in combination with ortho-prostheses.

Contraindications

• Insufficient residual muscle functions to guarantee safe use; lack of knee joint hyperextension
• Not ability to influence knee joint extension by means of a dorsal stop
• More than 15° flexion contracture in the knee joint
• Cognitive disorders
• Severe spasms so that consistent functionality is not guaranteed
