Electronic Von Frey
The electronic model of Von Frey filament combines ease of use and rapidity for the determination of mechanical sensitivity thresholds in rodents. This easy-to-use and precise instrument is a must-have reference for research in analgesia, nociception, neuro-pathologies, and post-operative pain. The pain sensitivity of an animal or person is important to know when delving into life science research related to pain research, neuropathy assessment, and the testing for analgesic drug. Electronic Von Frey aesthesiometers, also known as electronic Von Frey Analgesiometer, assess mechanical allodynia, which is a painful response to a light touch or pressure from a stimulus that is not normally painful or hyperalgesia.
The device applies a gradually increasing force to the paw using a fine probe until a withdrawal response is observed. The peak force required to elicit this response is automatically recorded, providing an accurate measure of the paw withdrawal threshold.
