What is Phalen's Maneuver? Phalen's Maneuver is a diagnostic test used to detect carpal tunnel syndrome. Named after Dr. George S. Phalen, this simple yet effective test involves flexing the wrists and holding them in that position for about 60 seconds. If tingling, numbness, or pain occurs in the fingers or hand, it suggests the presence of carpal tunnel syndrome. This test helps doctors identify the compression of the median nerve, which is responsible for the symptoms. Understanding Phalen's Maneuver can be crucial for early diagnosis and treatment, preventing further complications. Let's dive into 50 fascinating facts about this important medical test!
