The shoulder and thoracic spine are closely linked, both in terms of anatomy and development of pain and dysfunction.
We have several muscles that run the length of the thoracic spine that attach to the scapula and shoulder. From the front we have the pectoralis major and minor and serratus anterior, and from the back we have the trapezius, rhomboids and lats. If the thoracic spine is not moving well the shoulder can hurt. If the shoulder is weak or tight, the thoracic spine can hurt.
Why would the thoracic spine cause shoulder pain though?
If we have poor posture or stiffness through the t-spine, we are likely going to be unable to get into a good position to extend or rotate. This can cause the “tech-neck” or the slumped posture from working in a sitting position or doom scrolling on our phones.
Why does it matter?
When we lack extension in the t-spine it limits our ability to fully flex the shoulder overhead. When that happens the scapula will try to compensate by elevating and getting out of the way. What actually happens though, is that the front of the scapula called the acromion gets right in the way we get a pinching in the space between the shoulder blade and the arm. This causes inflammation and repeated inflammation is what causes a rotator cuff tear.
And to think all you had to do to avoid shoulder surgery may have been a little bit of thoracic mobility???
Another cool thing about the thoracic spine is that as soon as you correct posture in the t-spine the c-spine follows suit and corrects itself! You can say goodbye to neck pain as well if you have a great t-spine.
If you happen to be dealing with neck or shoulder pain and think this might be addressing your problem, hit the button and book a phone consultation today. We treat overhead athletes and normal every day Joe’s who have thoracic problems limiting their sport and day to day function. Don’t let it be you!
