The Baseline Retracting Monofilament is a discrete, portable tool for detecting changes in neurological status. Retracting monofilaments are ideal for monofilament tests to evaluate potential peripheral neuropathy in patients with diabetes, but can also be used for various neurological status testing. The simple, retractable design of Baseline retracting monofilaments protects the filament during transportation and makes the testing process quick and easy.
