Maximilian von Frey (1852-1932) introduced a device in 1896 to determine touch and pain sensibility in humans. In the 1896 Frey proposed that pain is an independent tactile quality. He was trying to identify points on the skin, which responded specifically to touch, heat, cold, and pain. To do so, he developed an aesthesiometer, made from human hairs and animal bristles of different lengths. These were attached to at a right angle to a thin rod. The bending force of the bristle or hair can be measured and calibrated. Now optical glass fibres are used. The test is often used in clinical settings or in animal experiments. Von Frey tests rely on response from the test subject – e.g. a physical movement in animals or a verbal or physical response in people.
