Abstract

OBJECTIVE: High resolution ultrasonography is a non-painful and non-invasive imaging technique which is useful for the assessment of shoulder pain causes, as clinical examination often does not allow an exact diagnosis. The aim of this study was to compare the findings of clinical examination and high resolution ultrasonography in patients presenting with painful shoulder.
METHODS: Non-interventional observational study of 100 adult patients suffering from unilateral shoulder pain. Exclusion criteria were shoulder fractures, prior shoulder joint surgery and shoulder injections in the past month. The physicians performing the most common clinical shoulder examinations were blinded to the results of the high resolution ultrasonography and vice versa.
RESULTS: In order to detect pathology of the m. supraspinatus tendon, the Hawkins and Kennedy impingement test showed the highest sensitivity (0.86) whereas the Jobe supraspinatus test showed the highest specificity (0.55). To identify m. subscapularis tendon pathology the Gerber lift off test showed a sensitivity of 1, whereas the belly press test showed the higher specificity (0.72). The infraspinatus test showed a high sensitivity (0.90) and specificity (0.74). All AC tests (painful arc II(a), AC joint tenderness(b), cross body adduction stress test(c)) showed high specificities ((a)0.96, (b)0.99, (c)0.96). Evaluating the long biceps tendon, the palm up test showed the highest sensitivity (0.47) and the Yergason test the highest specificity (0.88).
CONCLUSION: Knowledge of sensitivity and specificity of various clinical tests is important for the interpretation of clinical examination test results. High resolution ultrasonography is needed in most cases to establish a clear diagnosis.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
