1.5 Contraindications

A fitting is not indicated with knee joint contractures that make it impossible to take the load off
the knee joint lock in order to release the orthosis knee joint.
NOTICE
To ensure optimal functionality of the orthosis, the patient must generate a knee extension moment
before heel lift-off and also at heel strike.
INFORMATION
Not for use as a permanently locked orthosis with unilateral application.

1.6 Function and design

1.6.1 Function
The E-MAG Active is a knee joint system with stance phase control, which offers the patient a
free swing-through phase and locks the knee joint for a secure stance phase prior to heel strike.
The E-MAG active is equipped with an electronic lock; the lock is released after the stance
phase, i.e. during toe-off, allowing the patient to swing the paralysed leg in a physiological man-
ner. Prior to heel strike, the knee joint locks in the extended position and the patient can safely
put weight on the foot.
