What does a positive Phalen's test indicate?

A positive Phalen's test indicates that the patient may have carpal tunnel syndrome. This test is specifically designed to provoke symptoms of median nerve compression, which is characteristic of carpal tunnel syndrome. During the test, the patient is asked to flex their wrists by placing the dorsal sides of their hands together for about 60 seconds. If this maneuver elicits numbness, tingling, or pain in the distribution of the median nerve, it suggests that the median nerve is being compressed, commonly due to swelling in the carpal tunnel.

Carpal tunnel syndrome is a condition that arises from various causes, including repetitive motion, injury, or systemic conditions, leading to increased pressure within the carpal tunnel where the median nerve travels. The Phalen's test, therefore, serves as a valuable diagnostic tool in assessing this condition.

The other options do not directly relate to the findings of a positive Phalen's test. Ruptured ligaments could involve different tests focused on stability and pain in the joint area rather than symptom provocation through wrist flexion. A rotator cuff injury primarily affects shoulder function and would require a different set of clinical evaluations. Tendonitis usually refers to inflammation of a tendon which may present differently in clinical assessments and would not
