  1. Abbreviations. ACJ, acromioclavicular joint; PAR, positive anaesthetic response (≥80% post-injection reduction in pain intensity); NAR, negative anaesthetic response (<80% reduction in post-injection pain intensity); GHJ, glenohumeral joint; SAB, subacromial bursa; LHB, long head of biceps.
  2. Note: There were no statistically significant differences in frequency of imaging findings between the PAR and NAR groups (P>0.05).
