Elbow flexion test: which description is correct?

• A. Pt extends elbows and holds for 60 seconds
• B. Pt flexes elbows and holds for 60 seconds
• C. Pt pronates forearm and holds for 60 seconds
• D. Pt flexes wrists and holds for 60 seconds

Answer: (B)

The elbow flexion test is used to provoke symptoms from the ulnar nerve by placing the nerve under tension at the cubital tunnel. The correct approach is for the patient to actively flex the elbow fully and hold that position for about 60 seconds. This sustained flexion increases pressure within the cubital tunnel, so if numbness or tingling appears in the ulnar-innervated areas (the ring and little fingers), the test is considered positive. Extending the elbow or rotating the forearm without maintaining elbow flexion does not stress the ulnar nerve in the same way, and flexing the wrists isn’t the test for this nerve at the elbow.
