Scapula Stability

Your scapula (shoulder blade) is unstable by nature.  It is a big, flat bone that literally floats on top of the ribs.   As such, your scapula is vulnerable to postural issues.

What does an injury prone posture look like?

If the muscles of the chest are stronger than the muscles of the upper back, your shoulders will slump forward.

If the muscles at the top of your shoulders are stronger than the muscles below your scapula, your shoulders will climb up towards your ears.

Trapezius Bad Posture

.  The Trapezius muscle is often over-dominant in an injury prone shoulder.

Trapezius Bad Posture Front

This posture is easily identified by the alignment of the collar bones. When the scapula is drawn forward and upwards, the collar bones look V shaped, rather than flat.


Give some love to your Lower Trapezius….

The Lower Trapezius muscle draws the scapula towards the spine.  It balances out the ‘lift’ of the the Upper Trapezius, essentially connecting the shoulder to the torso and ‘core’.


From behind. We can see the Lower Trapezius, often weak and dysfunctional in unhappy shoulders. A strong lower trapezius will draw the shoulders back into good posture.


From the front. We can see the flat collar bones and open chest that we associated with a stable scapula.


If your lower trapezius is under active, you are likely to feel near constant discomfort in your neck/shoulder.   Every time you pick up a weight, or simply work at your desk, your upper trapezius is working over time.  As with most ongoing complaints, rest and massage can only go so far.  Address the strength imbalance and you will be rid of the issue for good.
