What indicates a positive result in Finkelstein's test?

A positive result in Finkelstein's test is indicated by the reproduction of pain along the wrist and thumb. This test is specifically designed to assess for De Quervain’s tenosynovitis, a condition affecting the tendons involved in thumb movement, particularly the abductor pollicis longus and extensor pollicis brevis.

During Finkelstein's test, the patient is instructed to make a fist with the thumb tucked inside the fingers, and then the examiner gently ulnar deviates the wrist. If the patient experiences sharp pain along the radial side of the wrist or over the first dorsal compartment, it confirms involvement of these tendons and thus a positive test result.

The other options might relate to different conditions or movements, but they do not accurately reflect the purpose and expected outcome of Finkelstein's test.
