The aim of the present study is to determine whether adding shockwave therapy (SWT) to a progressive exercise program improves shoulder pain and function in individuals with rotator cuff tendinopathy (RC tendinopathy). Ninety patients diagnosed with rotator cuff tendinopathy will be randomly allocated into two groups: active SWT plus a progressive exercise program or placebo SWT plus a progressive exercise program. Primary outcomes will be measured using the Constant-Murley Score function questionnaire and by assessing patient-reported pain intensity with the numerical pain rating scale. Read More

Poor tendon to bone healing following rotator cuff repair has led to the continued interest and investigation into biological augmentation. The biology of tendinopathy is not fully understood and consequently the availability of disease modifying therapeutic targets is limited. A ceiling of benefit has been reached by mechanical optimisation of rotator cuff repair and thus, in order to improve healing rates, a biological solution is required. Read More

Abstract: Treatment of musculoskeletal conditions in athletes with extracorporeal shockwave therapy (ESWT) is gaining popularity as greater evidence supports its use. ESWT protocols (describing energy flux density, number of impulses, type of shockwave (focused or radial), number/frequency/duration of treatment session, area of application, and postprocedural therapy protocols) can be adjusted in the clinical setting. Protocols vary across studies, and optimal protocols for most indications are yet to be determined. Read More

The rotator cuff has an important role in the stability and function of the glenohumeral joint. It is a complex anatomic structure commonly affected by injury such as tendinopathy and cuff tears. The rotator cuff helps to provide a stabilising effect to the shoulder joint by compressing the humeral head against the glenoid cavity via the concavity compression mechanism. Read More

Calcific tendinopathy (CT) is a very common condition caused by the deposition of calcium hydroxyapatite crystals in tendons and it can be an incidental finding or associated with severe pain. CT can be easily detected by first level exams such as traditional radiography and ultrasound (US), which provide information on the site, extent and composition of the calcific formation. Classically, the most affected site is represented by the rotator cuff tendons, in particular the supraspinatus tendon. Read More

Background: Calcific tendonitis of the rotator cuff is due to carbonated apatite deposits in the shoulder tendons. During the evolution of the disease, an acute inflammatory episode may occur leading to the disappearance of the calcification. Although hydroxyapatite crystal-induced inflammation has been previously studied with synthetic crystals, no data are available with calcifications extracted from patients suffering from calcific tendinopathy.
