BACKGROUND Subacromial impingement syndrome (SAIS) is the most common disorder of the shoulder. The evidence for the effectiveness of treatment options is inconclusive and limited. Therefore, there is a need for more evidence in this regard, particularly for long-term outcomes. HYPOTHESIS Platelet-rich plasma (PRP) would be an effective method in treating subacromial impingement. STUDY DESI...

The most common cause of impingement syndrome is mechanical irritation of the subacromial bursa and rotator cuff by the coracoacromial arch. Offending structures include the undersurface of the anterolateral acromion, coracoacromial ligament, and the undersurface of the distal clavicle. We present a case of impingement syndrome caused by mechanical irritation of the rotator cuff by a subacromia...

Bicipital peritendinous effusion (BPE) is the most common biceps tendon abnormality and can be related to various shoulder ultrasonographic findings. Since the association of BPE with subacromial impingement is unclear, our study aimed to explore its association with the dynamic subacromial impingement test during ultrasound (US) imaging. We included 337 shoulders referred for US examinations a...

BACKGROUND The physiotherapy dynamic humeral centring (DHC) aims to prevent subacromial impingement of rotator cuff tendons during elevation of the arm. The objective of the study was to determine whether DHC acts via an effect on subacromial impingement mechanism by assessing its effect on painful elevation of the arm in subacromial impingement syndrome. METHODS This is a secondary analysis ...
