Final answer:
Finkelstein's Test is a diagnostic procedure used to identify De Quervain's tenosynovitis. The test involves the patient making a fist with the thumb tucked inside and then tilting the hand downwards.
Step-by-step explanation:
The maneuver described by the student in which the patient places the thumb inside a closed fist, then tilts the hand down is known as Finkelstein's Test. This test is used to diagnose De Quervain's tenosynovitis, a form of tendinitis in the wrist. It assists in identifying the pain caused by the inflammation of the tendon sheath of the abductor pollicis longus and extensor pollicis brevis muscles in the thumb. Specifically, when performing Finkelstein's Test, the patient bends the fingers to make a fist which helps to stabilize the wrist, and then tilts the hand to the side away from the body to elicit symptoms.
