For vibration and position sense, test the ______ and ______ first. If results are normal, can assume the more ______ areas are also normal

Explanation:
Vibration and position sense depend on large-fiber pathways in the dorsal columns, and in many conditions deficits start in the most distal parts of the limbs. Testing the most distal areas first—fingers and toes—helps reveal a stocking-glove pattern of loss if present. If those distal modalities are normal, you can reasonably infer that the more proximal regions are also normal, saving time and guiding the investigation. The other options mix distal and proximal or involve areas not typically used to assess these modalities, so they’re less efficient for the initial screen.
