Van Boven Domes

This is a new method of assessing cutaneous spatial resolution. Each of the 8 acrylic probes have a dome shaped head with alternating ridge/slot patterns of different widths. The ridged head is pressed against the skin, and the patient/subject reports the alignment of the ridges, longitudinal or transverse. Recent research shows that: 1) The Van Boven domes detect reported sensitivity deficits that cannot be detected or quantified with Von Frey hairs or two point calipers. 2) Measurements are reproducible and are not subject to learning effects. 3) The neuroanatomical basis for performance in this test is the density of innervation of mechanoreceptive afferents (touch fibers). (Van Boven and Johnson, The Limit of Tactile Spatial Resolution in Humans, Neurology 44: 2361-2366, 1994). Blank and replacement domes also available $75. Set of 8 in case. Product ID. VanBovenDomes
