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.

Is nylon a monofilament?

Monofilament can be extruded from different materials, but nylon is by far the most common and popular medium. Often, different varieties of nylon are blended together into co- and multi-polymers to produce varying degrees of stretch, strength, abrasion resistance and other important attributes.

What is Semmes-Weinstein monofilament test?

The Semmes-Weinstein Monofilament test is a sensory assessment tool. This assessment tool consists of a set of monofilaments that vary in thickness and diameter, the gradient forces of these monofilaments ranges from . 086 gm to 448gm. These monofilaments are used to map out sensory loss.

What is the monofilament test?

What is 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. It is a small strand of nylon attached to a plastic base. Your doctor will have you sit or lay down and most likely have you close your eyes.

Why do we use 10g monofilament?

The 10g monofilament is an objective, 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 is an abnormal 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.

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.

How do you do a 10g monofilament test?

Hold the monofilament perpendicular to the foot and with a smooth, steady motion, touch the skin until the monofilament bends approximately 1 cm (see Diagram A). Hold it against the skin for approximately 2 seconds. 7. Using the monofilament , randomly test 10 sites on each foot as indicated in Diagram B.

How is the monofilament test scored?

1. If all sites are tested and the client feels the monofilament in each of the areas; then the score is 10/10. 2. If the monofilament is not felt in an area on the foot, this indicates loss of protective sensation (LOPS) in that area and requires referral to a physician / NP.

Why is monofilament test performed?

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.
