Objective: To compare the accuracy of combinations of clinical examination findings for predicting a positive response to injection of local anaesthetic into the subacromial bursa.

Design: Prospective, cohort, diagnostic validity design. Subjects: Consecutive patients with shoulder pain recruited from primary care physiotherapy and general medical practices.

Methods: All subjects underwent a standardised clinical examination (index test) followed by a diagnostic injection of xylocaineTM into the subacromial bursa (reference standard test) performed under ultrasound guidance. Clinical examination variables associated with a positive anaesthetic response (≥ 80% post-injection reduction in pain intensity) were identified (p

Results: Of the 196 subjects who received …
