Six-months ago, he noticed that his vision is a bit blurred, sometimes he may have floating clouds in his vision that are not actually there which usually clear on its own. Kenrick is four feet seven inches and weighs 200 lbs, medium-frame built but an apple-shaped body-type. He has a waist is 120 centimetres and a hip of 90 centimeters.

Touching a specialized caliper to the surface of the skin will measure the distance between two points that are perceived as distinct stimuli versus a single stimulus. The patient keeps their eyes closed while the examiner switches between using both points of the caliper or just one. The patient then must indicate whether one or two stimuli are in contact with the skin. Why is the distance between the caliper points closer on the fingertips as opposed to the palm of the hand? And what do you think the distance would be on the arm, or the shoulder?arrow_forward
