Shoulder Impingement and Common Chronic Shoulder Pain Explained

Shoulder impingement syndrome refers to pain and functional limitation caused by irritation or compression of structures within the subacromial space—most commonly the supraspinatus tendon or the subacromial bursa. While the term “impingement” was once used to imply a purely mechanical process, modern research recognizes it as a multifactorial condition involving tendon load tolerance, neuromuscular control, posture, scapular motion, and sometimes structural factors such as acromial shape or osteophytes. Patients typically report pain during overhead activities, reaching away from the body, or lifting objects in front of them. A common feature is the “painful arc,” where mid-range elevation triggers discomfort, while lower and higher portions of the movement feel easier. Night pain, especially when lying on the affected shoulder, is also frequently described. Importantly, the majority of symptomatic cases are not caused by physical “pinching” alone. Changes in rotator cuff coordination, fatigue, or altered scapular mechanics can all reduce the subacromial space or increase tendon stress. Because of this, rehabilitation focuses on improving movement patterns, restoring muscle balance, and increasing tendon resilience—rather than relying solely on strategies intended to create more space. Subacromial impingement syndrome is the most common shoulder complaint in orthopedic clinics (44–65%) and the most frequent cause of shoulder pain in over-arm athletes.
