What symptoms indicate a positive Elbow Flexion Test?

The Elbow Flexion Test is specifically designed to evaluate for ulnar nerve entrapment or irritation at the elbow. A positive result is indicated by the presence of tingling or paresthesia in the distribution of the ulnar nerve, typically affecting the little finger and half of the ring finger. This symptom demonstrates that the ulnar nerve is being compressed or irritated, especially during the flexion of the elbow, which is when the space for the nerve becomes more constricted.

While pain in the elbow and symptoms over the medial epicondyle might also occur with various elbow conditions, they do not specifically correlate to the ulnar nerve's health or entrapment, which is the primary focus of the Elbow Flexion Test. Similarly, weakness in the forearm may arise from muscle issues or different nerve entrapments but does not specifically diagnose ulnar nerve involvement. Therefore, tingling or paresthesia in the ulnar nerve distribution is the hallmark symptom that confirms a positive Elbow Flexion Test.
