ABSTRACT Diagnostic labels for shoulder pain (e.g., frozen shoulder, impingement syndrome) are widely used in international research and clinical practice. However, about 10 years ago it was shown that the criteria to define those labels were not uniform. Since an ongoing lack of uniformity seriously hampers communication and does not serve patients, we decided to evaluate the uniformity in definitions. Therefore, we compared the selection criteria of different randomised controlled trials (RCTs). This comparison revealed some corresponding criteria, but no uniform definition could be derived for any of the diagnostic labels. Besides the lack of uniformity, the currently used labels have only a fair to moderate interobserver reproducibility and in systematic reviews none of the separate trials using a diagnostic label show a large benefit of treatment. This, altogether, seems sufficient reason to reconsider their use. Therefore, we strongly suggest to abolish the use of these labels and direct future research towards undivided populations with "general" shoulder pain. Possible subgroups with a better prognosis and/or treatment result, based on common characteristics that are easily and validly reproducible, can then be identified within these populations.

    ABSTRACT: To investigate the inter-examiner reliability of Mechanical Diagnosis and Therapy (MDT)-trained diplomats in classifying patients with shoulder disorders. The MDT system has demonstrated acceptable reliability when used in patients with spinal disorders; however, little is known about its utility when used for appendicular conditions.

    ABSTRACT: To examine the interobserver reliability, internal consistency, and clinical importance of 3 clinical tests for the assessment of scapular positioning in patients with shoulder pain. Prospective repeated-measures design. Private practices for physical therapy and hospital outpatient physical therapy divisions. Twenty-nine patients with shoulder pain who were diagnosed by a physician as having a shoulder disorder. Not applicable. Study participants filled in a visual analog scale for pain and the Shoulder Disability Questionnaire. Next, 2 assessors performed the following tests: measurement of the distance between the posterior border of the acromion and the table, measurement of the distance from the medial scapular border to the fourth thoracic spinous processes, and the lateral scapular slide test. The interobserver reliability coefficients were greater than .88 (intraclass correlation coefficients) for the measurement of the distance between the posterior border of the acromion and the table, were greater than .50 for the measurement of the distance from the medial scapular border to the fourth thoracic spinous processes, and were greater than .70 for the lateral scapular slide test. The Cronbach alpha coefficient for internal consistency for all tests was .88. No associations between the outcome of the tests and self-reported pain severity or disability were found. These data provide evidence favoring the interobserver reliability of 2 of 3 tests for the assessment of scapular positioning in patients with shoulder pain. The clinical importance of the tests' outcomes, however, is questionable.

    ABSTRACT: Background: Shoulder complaints are among the commonest causes of musculoskeletal pain. They are potentially disabling and frequently cause absenteeism from work and claims for sickness benefits. One of the most prevalent subtypes of shoulder pain is impingement. This is often managed physiotherapeutically, with 'hands-on' manual therapy and exercises being mainstays. Objectives: To assess the effectiveness of manual therapy and exercises to improve pain, disability and function in people with shoulder impingement. Methods: A systematic review was conducted including systematic reviews, quasi-randomized trials and randomized controlled trials published up to October 2008. Searches included the Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Medline, Embase, Cinahl and PEDro. Methodological quality and risk of bias were assessed with appropriate instruments. All findings were critically analysed and discussed, and summary conclusions formulated. Results: Eight systematic reviews and six randomized controlled trials were included. Methodological quality and risk of bias as well as population and treatment parameters varied. Clinical heterogeneity prevented meta-analysis, thus all findings were synthesized narratively. The included research provides limited evidence to support the use of manual therapy and exercise interventions for shoulder impingement. This primarily relates to subacute and chronic conditions and short to medium-term effectiveness. Conclusions: Manual therapy and exercise seem effective for shoulder impingement, but varying methodological quality and risk of bias in reviews and trials warrant caution in the interpretation of the results. There is a need for further good-quality primary research.
