Ambroise Dynamic Wrist Orthosis

Ambroise Dynamic Wrist Orthosis

Treats a wrist drop and prevents shortening of the paralyzed muscles

Dynamic lift, without wrapping the hand

Have you lost control over lifting your hand? Do you have reduced strength in your wrist? Then you may not be able to lift your hand enough and use it properly: also called ‘wrist drop‘. For example this can be the effect of nerve damage to the arm due to a fracture or when the nerve is being pinched off too long, but also due to paralysis after a stroke.

The Wrist Orthosis ADWO gives you control over your wrist

The Ambroise Dynamic Wrist Orthosis (ADWO) is a lightweight wrist orthosis (also known as wrist splint or wrist brace) that pushes the hand up dynamically with the aid of an adjustable spring. The orthosis is very comfortable because contact with the (palm of the) hand and arm is kept minimal. This way you get maximum function over your wrist and hand with minimal intervention.

Wrist drop

Lifting the hand is also called dorsal flexion. Several muscles of the forearm are active (including the m. extensor digitorum en de m. extensor carpi radialis (longus and brevis)). The control of these muscles can be impaired by nerve damage (radial nerve).
This can be the result of clamping that nerve or even nerve breakage for example due to a bone fracture such as a humerus fracture. The brains can also be responsible for the loss of control for example after suffering from a stoke (CVA).

If you cannot make dorsal flexion with your hand anymore, in other words: you can not lift the hand, the hand hangs down. It becomes difficult to use the hand properly. This is also called ‘wrist drop’. This serious condition greatly reduces the functional possibilities of the hand, because only activities with the fingers primarily pointed downwards are still more or less possible.


No longer being able to extend the hand, is also called wrist drop syndrome.

Donning the Ambroise Wrist Orthosis

The ADWO is easy to don. Put the forearm through the orthosis untill the the palm of the hand leans on the hand tube. The hand tube must lie in the middle of the hand fold.

Maintenance of the ADWO

The ADWO can be cleaned with a damp cloth.

Custom made for perfect fit

The ADWO is generally worn for longer periods of time. Most users even wear it all day. Therefore, the orthosis must fit well and be properly adjusted to your hand and forearm. That’s why the ADWO is delivered as a custom fitted product. We can individually fit the orthosis for you, but also your local orthotist can help you.

Treatment is necessary

Do not leave your complaints untreated for too long. We may be able to increase the function of your hand with the ADWO.

Minimal resources, maximum functionality

Especially, for people for whom an arm disorder is not congential, frustration can occur when daily activities can no longer be done. At Ambroise we try to restore maximum functionality of your hand with minimal resources. This is also the case with the Ambroise Dynamic Wrist Orthosis, the AWPO.

The hand lifted

With the ADWO, the hand is supported on the hand palm side by a smooth thin tube which fits perfectly in the fold of the hand. This hand lever is lifted by an ingenious spring system, so that the hand follows. By adjusting the spring force, the ADWO lifts your hand and bend your wrist without too much effort. Thus, the wrist’s movement is restored and you can use your hand again.
