Final answer:
The psoas sign is elicited by raising the leg against resistance and is associated with abdominal pain.
Step-by-step explanation:
The psoas sign or physical exam maneuver can be best described as abdominal pain elicited by raising the leg against resistance. The psoas muscle is located in the lower back and connects the spine to the thigh bone. When there is inflammation or irritation of the psoas muscle, such as in conditions like appendicitis or psoas abscess, lifting the leg against resistance can cause pain.
