The Semmes Weinstein Monofilament Test is used to test for loss of protective sensation in the foot. It’s a quick and easy test that can be performed in a doctor’s office. The test involves using a monofilament to apply pressure to the skin. If the patient does not feel the pressure, then they have lost protective sensation and are at risk for injuries.
How the Test Is Performed
The test is performed by applying pressure to the skin with a monofilament. The monofilament is a thin, flexible wire that is bent into a “U” shape. The doctor will press the monofilament against the skin at different points on the foot.
A positive result on the Semmes Weinstein monofilament test indicates that the patient has lost protective sensation. This means that they may not be able to feel pain or temperature changes in the affected area, which puts them at risk for injury. A positive result should be followed up with further testing to confirm the diagnosis and develop a treatment plan.
