One of the frequent causes of non-traumatic lower-limb amputation is Diabetes and is usually preceded by foot ulcer and infection. The reason of this ulceration is commonly a loss of protective sensation due to peripheral neuropathy, for which there is no prevention strategy. Current research promotes early detection of neuropathy so that secondary prevention measures, such as intensive foot-care education and treatment, can be used for individuals.
In an effort to standardize and simplify the detection of insensate foot, the 5.07/10-gm Monofilament is recommended by the International Diabetes Federation and the World Health Organization as a device that can be used by health professionals at every level of care.
Health care providers can lower the incidence of lower extremity amputation by using a Semmes-Weinstein 10gm monofilament to identify protective sensation loss and quickly taking measures to prevent ulceration. Monofilaments are an effective, convenient, easy to use, relatively inexpensive way of testing for loss of protective sensation in the feet in daily clinical practice.
The Longevity and recovery testing suggest that the life of each monofilament can be extended after testing on 10 patients by leaving it to recover for 24 hours before further use. Worldwide research indicated testing from 2 to 10 sites per foot with monofilaments and we recommend to test at least 6 per foot.
