| Sensation threshold screening using a 10 gram monofilament(also known as Semmes-Weinstein monofilament) |
| 1. Use the 10g monofilament to test sensation. |
| 2. The sites to be tested are indicated on the foot diagram below. |
| 3. Apply the filament perpendicular to the skin's surface ( see Diagram A). |
| 4. The approach, skin contact and departure of the monofilament should be approximately 1.5 seconds duration. |
| 5. Apply sufficient force to allow the filament to bend ( see Diagram B). |
| 6. Do not allow the filament to slide across the skin or make repetitive contact at the test site. |
| 7. Randomise the order and timing of successive tests. |
| 8. Do not apply to an ulcer site, callous , scar or necrotic tissue. |

| The circles represent the places on the foot to test with the monofilament | | |
| Consider your feet to be "at risk" if you cannot feel the 10gm monofilament at any of the sites marked. |
