The patient\u2019s symptoms and the context suggest potential hip or lumbar spine involvement. The goal is to determine which action, performed while the patient is in the left decubitus position, will provide diagnostic confirmation. In this case, performing 'Internal Rotation' of the right leg is likely to elicit pain if there is an underlying hip pathology, thus confirming the diagnosis."}
