Von Frey Testing

WPI's Electronic von Frey Anesthesiometer is used to measure sensory thresholds in test subjects with amazing accuracy and ease.

The Electronic von Frey Anesthesiometer was developed to assess mechanical allodynia, which is a painful response to a light touch or pressure from a stimulus that is not normally painful.

The pain sensitivity of a person or animal is important to know when delving into related life science research like pain research, neuropathy assessment, and the testing for analgesic drug discovery. Having the necessary equipment to get the most accurate results possible is critical. Electronic von Frey aesthesiometers, also called electronic von Frey analgesiometers, assess mechanical allodynia, which is a painful response to a light touch or pressure from a stimulus that is not normally painful or hyperalgesia, which is increased pain sensitivity. With a series of rigid tips and flexible von Frey hairs, you can test the pain receptors in the skin. Electronic von Frey apparatuses make gauging subject comfort a simple process, allowing you to get more out of your research in less time.

WPI's electronic von Frey meter enables researchers to plug up to three probes into a single unit. To test pain and sensory thresholds it is supplied with either a 90 g, 800 g or 1000 g probe and rigid tips. Options include a set of 15 different flexible von Frey hairs called “SuperTips™”. Each hair, regardless of model chosen, is exactly 0.8 mm in diameter. This uniformity of design eliminates false readings and allows for comparison of test results. The Electronic von Frey can be used with chart recorders and analogue/digital converters. Mesh stands are available in a variety of sizes for large group studies.
