A wrist brace for relaxing extensor musculature in a forearm having a first body, a second body, and at least one hinge joint hinging the first and second body together. The first body is arranged to be secured to a forearm while the second body extends from the hinge to a palm of the hand belonging to the forearm. A force generator, such as a leaf spring, is adapted to generate a moment of force between the first and second body, such that the second body, hinging relative to the first body, presses against the palm of the hand in a direction directed towards the upper side of the hand belonging to the palm, and wherein the moment of force is at least exerted on the hand when the hand is extended in line with the forearm. |

DETAILED DESCRIPTION The aid and method according to the invention are both based on the principle of the flexor-extensor antagonism and can be used for physiologically relaxing an extensor musculature.
This extensor musculature is an extensor muscle, i.
e.
an extensor in the forearm which is connected to the lateral epicondyle.
The extensor musculature is in antagonistic action with the flexor musculature.
The object of the invention is to relax the extensor musculature in the forearm.
To this end, an aid according to the invention is characterized in that it is provided with a first body, a second body and at least one hinge joint hinging the first and the second body together, the first body being arranged to be secured to a forearm while the second body extends from the hinge to a palm of the hand belonging to the forearm, the aid being further provided with resilient means which, in use, generate a moment of force between the first and second body such that the second body, hinging relative to the first body, presses against the palm of the hand in a direction directed towards the upper side of the hand belonging to the palm.
In the forearm to which the aid is secured, a wearer of the above-mentioned aid will experience a moment of force equivalent to a moment of force which is created by flexing the extensor musculature.
As a result, the flexor musculature will be flexed.
The extensor musculature is thereby physiologically relaxed.
Relaxation of the extensor musculature is one of the possible applications of the invention which can be of interest in the case of injured extensor musculature.
An example of an injured extensor musculature is a so-called tennis elbow.
Such as injury occurs frequently.
This injury results in pain stimuli coming from the origin of the extensor musculature at the elbow.
This origin is the epicondyle.
Physiological relaxation of the extensor musculature reduces the pain stimuli and promotes recovery of the injury.
Heretofore, in case of an injury to the extensor musculature, use is made of straps being tied around the forearm
