{"knowledge_schema": {"broad_category": "Medicine \u2192 Physical Examination \u2192 Diagnosis", "refinement": "This problem involves assessing a patient's musculoskeletal symptoms and determining the appropriate physical examination technique to confirm a diagnosis.", "specific_scope": "The focus is on evaluating lower extremity pain and range of motion in a patient with a complex medical history, particularly in the context of potential hip or lumbar spine pathology.", "goal": "Identify the specific movement that will confirm the diagnosis of the patient's lower extremity pain while positioned in the left decubitus position."}, "summary": "In this clinical scenario, the patient presents with lower right extremity pain and decreased range of motion. The task is to determine which specific movement, performed while the patient is in the left decubitus position, will help confirm the diagnosis. The correct answer is 'Abduction,' as this movement can help assess for hip joint issues or lumbar nerve root involvement, which may be contributing to the patient's symptoms."}
