Certified Hand Therapist (CHT) Practice Exam 2025 - Free CHT Practice Questions and Study Guide

Cozen's test is specifically designed to evaluate lateral epicondylitis, which is also commonly referred to as “tennis elbow.” During this test, the practitioner instructs the patient to make a fist and extend the wrist while providing resistance against wrist extension. A positive result, indicated by pain in the area of the lateral epicondyle, supports the diagnosis of lateral epicondylitis. This test effectively isolates the muscles and tendons involved in elbow extension and wrist movements, providing a direct assessment of pain related to the common extensor tendon, which is typically affected in lateral epicondylitis.

In contrast, the other tests mentioned are not specific to lateral epicondylitis. Phalen's test is primarily used to assess carpal tunnel syndrome, Finkelstein's test is utilized to diagnose de Quervain's tenosynovitis, and Tinel's sign is employed to detect nerve compression or damage involving the ulnar or median nerves. Each of these tests pertains to different conditions affecting the wrist or forearm, which highlights why Cozen's test is the most appropriate choice for confirming a diagnosis of lateral epicondylitis.
