Sensory discrimination testing.
Occlude vision during sensory testing. This quality-made wooden shield is a practical and comfortable way to administer sensory testing and stereognosis. Neoprene sleeves are shaped to effectively block the client from seeing testing items. The legs are removable for convenient storage.
All the items needed for evaluation are contained in one convenient kit. This handy kit contains 17 common items and matching cards for the evaluation of stereognosis. The 3" x 5" (7.6 x 13cm) cards are laminated for long-term use. Each card has a drawing and the name of the item in Spanish and English. The name is on the back of each card. Use this kit with the Sensory Testing Shield to retest clients and monitor improvement during treatment. Packaged in a sturdy plastic box.
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
