The extensor carpi radialis brevis can contribute to pain at the back of your wrist, also called the dorsum of the hand.
Pain from this muscle is mostly felt, if it is afflicted with trigger points or if is too tight. On this page you will learn how to free it from those points and excessive tension.
Additionally you can read about the causes and consequences of strain in this muscle as well as about its functions and insertions.
Feel free to start with the paragraph that is most relevant for you.
Due to its direct attachment at the wrist, this muscle can trigger pain at its back, hand and forearm, if it is too tight.
The same pain can be initiated if trigger points in this muscle are existent.
Beside the pain that you might feel at the back of your hand, it is possible that your grip weakens tremendously if your extensor carpi radialis brevis harbors active trigger points.
The weakness can rise to such an extent, that you might drop even the lightest objects, like a cup of coffee.
Why is that? Think like this: A strained muscle is mostly too tight, which means it has lots of tension in it.
Now your body doesn’t want you to place even more of that on the muscle, which would occur with a contraction or elongation.
In this case it tries to avoid that by „inhibiting“ and weakening your grip, respectively.
Because if you cannot grip hard, the muscle also doesn’t need to work and stabilize your wrist. I think that makes sense to you, doesn’t it?
