Shoulder pain is a substantial medical and socioeconomic problem in most societies, affecting the ability to work or carry out leisure time activities as well as subsequently influencing physical and psychological well-being. According to a nationwide survey in Finland, 27% of the population reported shoulder pain within the last 30 days. In clinical practice, imaging findings of structural abnormalities are typically thought to explain symptoms, even though such findings are also prevalent in asymptomatic individuals, particularly with increasing age. Overall, there is a paucity of high-quality evidence on the prevalence, clinical relevance and prognosis of 'abnormal' imaging findings of the shoulder.The aim of the Finnish Imaging of Shoulder (FIMAGE) study is fourfold: to assess (1) the prevalence of shoulder symptoms and the most common anatomical variants and imaging abnormalities of the shoulder; (2) the concordance between shoulder symptoms, function and imaging abnormalities; (3) the most important determinants of symptoms, function and imaging abnormalities; and (4) the course of shoulder complaints over 5 years.

Shoulder conditions are a major cause of morbidity in the general population. Many clinical practice guidelines (CPGs) for shoulder conditions have been developed. Their purpose is to provide evidence-based recommendations to assist clinicians in providing optimal care to maximise patient outcomes. The aim of this systematic review is to identify, appraise, and compare the content and quality of CPGs for atraumatic shoulder conditions.

To explore the outcome domains and measurement instruments reported in published randomized controlled trials of physical therapy interventions for shoulder pain (rotator cuff disease, adhesive capsulitis, or nonspecific shoulder pain).

The selection of appropriate outcomes or domains is crucial when designing clinical trials, to appreciate the effects of different interventions, pool results, and make valid comparisons between trials. If the findings are to influence policy and practice, then the chosen outcomes need to be relevant and important to key stakeholders, including patients and the public, healthcare professionals and others making decisions about health care. There is a growing recognition that insufficient attention has been paid to the outcomes measured in clinical trials. Recent reviews of the measurement properties of patient-reported outcome measures for shoulder disorders revealed a large selection of diverse measures, many with questionable validity, reliability, and responsiveness. These issues could be addressed through the development and use of an agreed standardized collection of outcomes, known as a core outcome set (COS), which should be measured and reported in all trials of shoulder disorders. The purpose of the present project is to develop and disseminate a COS for clinical trials in shoulder disorders.

To achieve consensus on the most important outcome domains to measure across all clinical trials for shoulder disorders.

Limited evidence is available on the cost-effectiveness of diagnostic imaging for back, neck, knee, and shoulder complaints. Decision analytic modelling may be an appropriate method to synthesise evidence from multiple sources, and overcomes issues with trial-based economic evaluations.
