Wearing instructions (pictorial guide)

Before using this device, please read the following instructions.

Correct application is integral to the device’s proper function and safety.
This device should be fitted by a health professional.

Intended use/indications
This device is designed to mobilise (stretch) the forearm into supination (palm facing up) or pronation (palm facing down).
Use this device with care and only for its intended use.

Uncovered, open wounds should not be in direct contact with the device. The device is not suitable for unstable joints, non-united fractures or in the presence of heterotopic ossification.

Force applied with the aim of stretching should be applied gently and gradually. Mild discomfort is normal, however severe, sharp, or increasing pain, changes in sensation (numbness, pins and needles) or skin reactions are not expected. Should you experience any of these, you should remove the device and consult your health professional.
Keep device away from heat, such as open flames.
Remove watch and wrist jewellery prior to application.

Please refer to the size guide found on the box or click here.

First fitting (by health professional)

1) Apply the upper arm padding.

2) Applying the frame: Slide the aluminium frame onto the wearer’s arm. Line up the upper struts with the humerus and press the struts to stick to the upper arm padding.

3) Adjust the length of the forearm component. The hinge should be in line with the elbow and the curved section should line up with the wrist crease. Loosen the screws using a screwdriver and slide to the desired length. Tighten the screws to maintain the length.

After the first fitting, the aluminium frame should remain attached to the upper arm padding.

Subsequent applications (patient use)

1) Fit cuff and frame: Slide the aluminium frame and upper arm padding on to the arm.

2) Tighten the strap to secure.

3) Applying the wrist wrap: Apply the wrist wrap in the desired direction (see 3a and 3b below) by the sliding loop over thumb, then wrapping around the wrist and securing with velcro tab.

(a) Supination (palm up) – Wrap around the back of the hand.


(b) Pronation (palm down) – Wrap around the front of the hand.

4) Position your forearm in the desired direction of rotation (palm up or down). Wrap the elastic straps around the wrist in the same direction as the wrist wrap. Both straps will go in the same direction and will wrap half a rotation to one rotation around the wrist.

a) Assisted

b) Without assistance

5) Thread the straps through the buckles using either of the following methods. One strap to one buckle.

(a) If there is less than 70° of rotation:
thread both straps over the top (1) and through the buckle (2).


(b) If there is more than 70° of rotation:
thread the top-most strap through the hole under the buckle (1) then upwards (2) through the buckle (3). Thread the lower of the 2 straps over the top.

Push down on the tabs to lock the buckles.

6) Adjust the tension on each elastic strap to achieve the desired stretch. The stretch should be applied gently and gradually. Straps should be adjusted one at a time to achieve a central position of the wrist within the frame.

7) Slide any excess strap length through the strap keeper.

1) To release the buckles, lift up on the tabs.
2) Remove the elastic straps from the strap keeper and buckles.
3) Undo the velcro tab and remove the wrist wrap.
4) Slide the upper arm padding and the frame off the arm in one piece. If the upper arm padding is too firm, you may need to undo the velcro fastening for removal.
