Purpose[edit | edit source]
Resisted AC Joint Extension Test (or the AC Resisted Extension Test) is used to help identify acromioclavicular joint pathology in both traumatic and non-traumatic/chronic overuse cases,[1] and can be useful in helping differentiate between AC joint and impingement syndromes.[2]
Technique[3][edit | edit source]
- The patient is seated with the therapist standing behind him/her
- The patient's shoulder is positioned into 90 flexion and internal rotation, with the placed into 90 flexion
- The therapist places his/her hand on the patient's elbow and asks him/her to horizontally abduct the arm against isometric resistance
- A positive test is pain at the AC joint
Evidence[5][edit | edit source]
Sensitivity (%) | 72 |
Specificity (%) | 85 |
Positive Predictive Value (%) | 20 |
Negative Predictive Value (%) | 98 |
