monofilament

(mŏn′ō-fĭl″ă-mĕnt) [″ + filum, thread]
A strand of nylon used to assess sensation in peripheral nerves, especially in the feet of patients with diabetes mellitus and other neuropathic conditions. The inability to feel the prodding of a strand of monofilament on the foot in one or more locations is diagnostic of diabetic peripheral neuropathy.

AIMS AND OBJECTIVES: To evaluate the usefulness of the diabetic neuropathy examination score (DNE), diabetic neuropathy symptom (DNS) score, 10-g Semmes-Weinstein monofilament examination, ankle reflex and measuring vibration perception threshold (VPT) with a biothesiometer in the detection of diabetic polyneuropathy in type 2 diabetes patients and to seek an optimal screening method in diabetic clinic in the detection of diabetic polyneuropathy in type 2 diabetes patients.
Sensorineural tests should include depth sense and two-point discrimination using von Frey or Semmes-Weinstein monofilament hairs, calipers, or plastic blocks with split levels and widening grooves,[29] and one or more of the following tests: fingertip vibration threshold measurement (8 to 500 Hz with vibrometer instrumentation[30]), thermal hot/cold perception using Minnesota thermal discs[31] or instrumentation,[32] and current perception threshold (detection of a 0 to 10 mA current at 5, 250, and 200 Hz[33]).
