A 38-year-old construction worker reports hand weakness and difficulty gripping tools. Examination reveals atrophy of the thenar eminence and decreased sensation in the thumb, index, and middle fingers. What diagnostic test would most likely confirm the diagnosis of carpal tunnel syndrome?

MRI of the wrist

Electromyography (EMG) and nerve conduction studies

Ultrasound of the wrist

X-ray of the wrist

Answer and Explanation

The Correct Answer is B

A.   MRI of the wrist can help rule out other conditions, but it is not the most specific test for diagnosing carpal tunnel syndrome.
B.   Electromyography (EMG) and nerve conduction studies are the gold standard for diagnosing carpal tunnel syndrome. These tests measure the electrical activity of the muscles and the speed of nerve impulses to confirm nerve compression.

C.   Ultrasound of the wrist may be helpful in visualizing the median nerve but is not as definitive as EMG and nerve conduction studies.
D.   X-ray of the wrist would not be useful in diagnosing carpal tunnel syndrome as it does not show soft tissue or nerve involvement.
