The shoulder joint has the largest range of motion in our body. The stability of a mobile shoulder joint is mainly supported by the rotator cuff muscles. The space between the humerus bone and the acromion is very narrow. Poor posture may result in compensatory movements and tendons being squeezed and impacted by the shoulder humeral head. As a result, inflammation and pain are caused, which is called shoulder impingement syndrome.

When lifting the arm, shoulder tendons and soft tissues located underneath the acromion are easily jammed. If any excessive pulling or repeated vigorous lifting with the upper arm at an internally rotated position, the soft tissues inside the subacromial space can be impinged or triggered chronic inflammation. If the inflamed tendon is not properly recovered, the body subconsciously avoids touching the painful structures, which produces compensatory actions such as kyphosis or a round shoulder. Unfortunately, these compensatory actions often exacerbate the vicious cycle of tendon and soft tissue compression.



Risk Factors

Poor postures such as kyphosis and protracted scapula are the most common risk factor. Swimmers and athletes that often require lifting up arms (such as tennis, throwing sports, etc.) will repeatedly impact and stimulate the affected structures.


In addition, tight pectoral muscles and anterior deltoid muscles may cause excessive internal rotation and anteriorly tilting in the humerus when lifting arms, making the space between the acromion narrower and causing impingement.

Common Symptoms
  • Soreness around the shoulder, sometimes radiating to the back of the shoulder and forearm, obvious tenderness on top of the shoulder
  • Increased pain when raising the arms to a certain angle
  • Suffering from redness, swelling, heat, and pain after activity, in severe cases, the muscle strength of the cuff muscles weakens and the shoulder joint becomes stiff




During the acute phase, rest and avoid pain-provoking activities. Apply ice to the affected area to reduce pain and inflammation. In severe cases, anti-inflammatory and pain-relieving drugs should be taken as prescribed by a doctor. In terms of physiotherapy, manual therapy, acupuncture, and electrophysical therapy can help reduce inflammation and relax muscles. When inflammation begins to subside, patients need to stretch to keep their shoulder joints moving under normal biomechanical conditions. Targeted shoulder strength training, such as stabilization of the rotator cuff muscles and endurance training is also very important. If shoulder muscles are balanced, it can effectively control normal shoulder movements and reduce the chance of poor movements and shoulder impingement. If shoulder muscles are balanced, it can effectively control normal shoulder movements and reduce the chance of poor movements and shoulder impingement.
