tactile stimulus von Frey monofilament stimulus 2024-02-19T15:10:13Z PMID:34808752 This is any condition in which the main influencing factor is a Von Frey monofilament stimulus, usually encountered in a Von Frey assay, which is used to evaluate mechanical allodynia in laboratory rodents. The von Frey test, which may be manual or electronic, uses von Frey monofilaments (hair or fibers), which are small pieces of nylon rod, approximately 50 mm in length, and of varying diameters, to test a rodent's sensitivity to punctate mechanical pressure on the plantar surface of a rear paw. Von Frey filaments are able to deliver force in the range of 0.08 to 2940 mN. XCO:0001286 experimental_condition_ontology slaulederkind von Frey assay condition
