Which condition is NOT included in the pre-test probability for the patient's likely diagnosis?

• A. Systemic pathology
• B. Shoulder impingement
• C. Adhesive capsulitis
• D. AMBRI

Answer: (D)

In evaluating the pre-test probability for a patient's likely diagnosis, understanding common conditions that typically present with specific symptoms is essential. AMBRI, which stands for Atraumatic Multidirectional Bilateral Instability, is a specific shoulder condition that is categorized as a type of instability rather than a standard diagnosis considered in general pre-test probability assessments. Therefore, it is less likely to fall within the broader conditions that would be assessed when initially screening for a shoulder issue.

Conditions like systemic pathology, shoulder impingement, and adhesive capsulitis often present with more universally recognized symptoms and clinical findings that can be assessed through standard examination practices. These conditions are well-documented in literature and have established protocols for diagnosis and management. In contrast, AMBRI is specifically related to shoulder instability characterized by its unique presentation and often requires distinct assessment parameters, distinguishing it from the more commonly encountered conditions when evaluating a patient's likelihood of certain diagnoses.
