Bending the joint
The material from both the corrective joint and the free motion / R.O.M. Joint is proximal and distal
partly depleted (just below and above the Bar adapter). This allows to bend the joint as needed.
Do not use bending irons but rather position the joint with a mounted Bar horizontally in a vice and
push / pull the hinge into the desired position by hand.
Mounting the joint onto the Bars
Various Bar models are available in several widths and thicknesses. Select the Bar you need. Once you
have adjusted the Bars to the contours of the limb, place the bars with the countersunk part facing
down (!) over the attachment bushes of the joint. Use the supplied screws to fasten the bars and secure
them with Loctite. TIP: If needed, you may loosen the attachment bushes and place them the other way
around, allowing you to mount the Bars underneath instead of on top.
Locking the joint
In order to more easily position and remove the orthosis, the joint can be locked at virtually each
desired angle. Distally from the power indicator window is the locking mechanism. The locking catch
points distal as long as the joint is unlocked. In order to lock the joint, the catch should be pushed
forward/up.
CAUTION
BEWARE OF RISK OF INJURY BY UNLOCKING. BEFORE UNLOCKING THE JOINT, NOTE THE SPRING TENSION SETTING. IF
TENSION IS SET HIGH, IT MAY BE ADVISABLE TO HAVE A CARE GIVER ASSIST WITH UNLOCKING IN ORDER TO GRADUALLY
GUIDE THE ORTHOSIS TOWARDS THE SET FLEXION OR EXTENSION FORCE.
Setting flexion and extension stops
There are two screws at the back of the corrective MultiMotion joint to set the range of motion.
The standard stop setting in both corrective joints is 60° flexion and 60° extension. In the "Small"
model, these flexion and extension stops can be set in 14° increments. In the "Regular" model,
these increments are 12°. Use the supplied allen screwdriver to loosen the flexion and extension
screws, position them as needed and retighten them. In order to ensure correct functioning of the
joint, it is mandatory to set the flexion and extension stops. Otherwise, it may cause the spring to be
excessively stressed and overloaded.
Setting the spring tension
The allen screw at both sides of the joint is to set the spring tension using the supplied allen
screwdriver. In each phase, the optimal objective is to realize a wearing time of 7-8 hours a day,
uninterrupted without complications.
1st phase
Adaptation phase: set spring tension at minimal tension (Fig. A) and put the orthosis on the patient
(Fig. B).
2nd phase
Work up to sub-maximum spring tension: this is the maximum
spring tension the patient can tolerate for a period of 7-8 hours a day. Finding the sub-maximum
spring tension is done progressively.
This means: start at the lowest tension and gradually increase the spring tension (Fig. C) until spasm is
triggered. At that point, the tension should be slightly reduced (Fig. D) in order to relieve the spasm.
3rd phase
Rehabilitation: this is the phase where the patient's range of motion is progressively improved.
