The relative test of the thumb tip is a check-up test of the thumb-to-palm test. The test reflects the palm's dysfunction of the palm, mainly seen in the median nerve paralysis. The tip of the thumb is relatively inspected during the test. When the thumb is opposite to the fingertip of the little finger, the central axis of the two fingers can be on the same line. For example, the thumb finger end can only be on one side of the fingertip end, and the middle axes of the two finger end points are not on the same straight line, but at an angle.
