Moberg pickup test is used to assess median nerve function by evaluating which digits?

• A. Digits 4 and 5
• B. Thumb only
• C. Digits 1 through 3
• D. All five digits

Answer: (C)

The test targets sensory function of the median nerve as it relates to tactile recognition and precise hand use. It requires picking up small objects with the thumb, index, and middle fingers and identifying them, which relies on intact cutaneous sensation in those digits. The median nerve supplies sensation to the thumb, index finger, and middle finger (palmar surfaces), making these digits the ones most critical for the task. The ring and little fingers are less specifically tested here because they are mainly served by the ulnar nerve (with some mixed innervation for the ring finger). So this test focuses on the thumb, index, and middle fingers to assess median nerve function.
