Updating your narrative with research is absolutely necessary for a clinician. I have learned special tests for shoulder impingement in no less than 5 continuing education seminars, that's not to even mention physical therapy school. https://www.facebook.com/100063774721900/posts/1313334844135661/?mibextid=rS40aB7S9Ucbxw6v
The area between the humeral head and the acromion, coracoacromial ligament, and acromioclavicular joint is known as the subacromial (under the acromion) space. Within this space is the supraspinatus tendon, long head of the biceps brachii tendon, subacromial bursa (fluid-filled sac that reduces friction), and the capsule of the shoulder joint.
When most people discuss shoulder impingement, they are referring to these tissues being compressed in this space.
The shoulder impingement theory was popularized by a surgeon in the 1970’s before he proposed a surgery to treat the issue. Since then, here’s what we’ve learned:
1. If symptoms were solely caused by compression of these overlying structures, we’d expect their removal to improve symptoms and function. However, research demonstrates that subacromial decompression is no better than placebo surgery.
2. Subacromial decompression also doesn’t seem to change the long-term prevalence of rotator cuff tears. Rotator cuff tears are present in asymptomatic individuals and are more common as we age, like many other imaging findings.
3. Compression of tissues in the subacromial space is common, occurs equally in people with and without symptoms, and happens with normal, day-to-day tasks.
4. A smaller subacromial space is not correlated with symptoms or disability.
So shoulder impingement exists, but it’s not the bogeyman it’s been made out to be.
