Final answer:
Phalen's sign is associated with carpal tunnel syndrome.
Step-by-step explanation:
Phalen's sign is associated with carpal tunnel syndrome, which is a common condition that affects the hand and wrist. It is caused by compression of the median nerve as it passes through the carpal tunnel in the wrist. When the wrist is flexed for a prolonged period, such as during Phalen's test, it can exacerbate the symptoms of carpal tunnel syndrome.
To perform Phalen's test, the individual flexes their wrist and holds it in that position for 60 seconds. If they experience numbness, tingling, or pain in the fingers during the test, it is considered a positive sign for carpal tunnel syndrome.
Other diagnostic tests and clinical assessments are usually done to confirm the diagnosis of carpal tunnel syndrome.
