Diagnostic decision guideline for identifying pain arising from the acromioclavicular joint. Clinical tests found to be of most diagnostic value for identifying a predominant acromioclavicular joint pain source defined by ≥80% pain relief following injection of local anaesthetic into the acromioclavicular joint. Abbreviations: ACJ, acromioclavicular joint; sens, sensitivity; PTP, post-test probability of ACJ pain at the 80% pain reduction standard, based upon pre-test probability (prevalence) of 14%; HBB, hand-behind-back; GHJ, glenohumeral joint; ER, external rotation; abd, abduction; spec, specificity.
