What is 10g monofilament test?
The 10g monofilament is an objective and simple instrument used in screening the diabetic foot for loss of protective sensation. It is important that a properly calibrated device is used to ensure that 10g of linear. pressure are being applied so a true measurement is being assessed.
What does the Semmes Weinstein monofilament test identify?
The Semmes Weinstein monofilament examination is a significant predictor of the risk of foot ulceration and amputation in patients with diabetes mellitus.
What is a positive monofilament test?
Abnormal monofilament testing has positive likelihood ratios >7 and negative likelihood ratios ranging from 0.07 to 0.61 for diagnosing neuropathy in patients with diabetes.
Why is the 5.07 monofilament test used?
As a quantitative sensory test, a monofilament is used to test a single point of touch pressure. A 5.07/10 g monofilament is used to screen for the presence or absence of protective sensation [12, 13]. Several studies have explored whether a monofilament test is a useful screening tool for the early detection of DPN.
How do you use 10g monofilament?
Apply the monofilament perpendicular to the skin surface. Apply sufficient force to cause the filament to bend or buckle for 1-1.5 seconds. Apply the filament at the edge of and not on an ulcer, callus, scar or necrotic tissue. Do not slide the filament across the skin or make repetitive contact at the test site.
Why is monofilament test done?
Monofilament testing is an inexpensive, easy-to-use, and portable test for assessing the loss of protective sensation, and it is recommended by several practice guidelines to detect peripheral neuropathy in otherwise normal feet.
Who can perform a monofilament test?
A monofilament test, formally called a Semmes-Weinstein monofilament ( SWM) test, is done by a doctor, nurse or CDE to test for nerve damage.
