Scapular Stability, your shoulder core

When we think of the core, we usually refer to our abdominal muscles, but did you know the shoulder has its own core ??

To improve function, strength, posture and balance, we need all our muscle to do their job and at the right time. It all starts with the center, the stability muscles, which is considered the core.

The scapulothoracic joint relies on the coordinated dance of 17 muscles, as well as its mobility at three other joints — the acromioclavicular, sternoclavicular, and glenohumeral joints — to provide stability for the rest of the arm and shoulder.

The shoulder requires both mobility and stability in order to support and stabilize the rest of the upper extremity.

Think of the scapulae as the foundation of your house. Your house is only as sturdy as its foundation. Similar to a house, upper body strength relies heavily on the stability provided by the scapular muscles, which ground the upper extremities and allow for greater distal strength.

Any weaknesses can provoque a change is the muscle balance, the larger muscles will start to overwork and compensate for the smaller ones that are not doing their job.

Poor biomechanics and weakness of the shoulder "core" can also lead to overuse of the smaller muscles of the extremities (tennis/golfer's elbow, De Quervain tenosynovitis, etc).

A well balanced exercise program is key to avoid injuries in the upper body. In order to know where to start with your exercises, your physiotherapist can give you a specific selection adapted to your needs. 

In the following blog, we will show you an example of scapular stability exercise program as a basic to start with. Stand by for more !
