The resisted movement in Cozens sign is which action?

Explanation:
At lateral elbow tendinopathy, the pain is produced by stressing the common extensor tendon at its origin on the lateral epicondyle. Extending the middle finger against resistance directly loads the extensor digitorum tendon where it attaches, pulling on the lateral epicondyle. If tendinopathy is present, this loading reproduces pain, making middle finger extension the action that elicits the resisted movement in this sign. This isolates the tendon most involved, more than a general wrist extension task would.
