10g Monofilament Test (Protective Sensation) — 2022-11-25
Facility: Jothydev's Diabetes & Research Centre, Mudavanmugal, Thiruvananthapuram
OP No: 4096
Patient age at time of study: 74 years
Result
All test sites: INTACT (✓) bilaterally
| Side | Sites Tested | Sites Intact | Loss of Sensation |
|---|---|---|---|
| Right foot | 8 | 8 | None |
| Left foot | 8 | 8 | None |
Interpretation
[!info] Monofilament Intact — Protective Sensation Present (Nov 2022)
Standard interpretation: Loss of sensation at ANY ONE of the 8 tested sites indicates a foot at HIGH RISK for ulceration and amputation.In November 2022, all 8 sites on both feet responded to the 10g monofilament — protective sensation was fully intact.
This is reassuring for the Nov 2022 timepoint, but must be contextualized with biothesiometry results from the same visit: vibration perception threshold was already elevated (Right avg 33V, Left avg 29V — moderate neuropathy risk range). This suggests that while gross protective sensation was intact, fine vibration sensitivity was already impaired.
Clinical Context
- The combination of intact monofilament but elevated biothesiometry VPT indicates the patient was in a transitional zone: protective sensation preserved but subclinical neuropathy detectable
- No subsequent monofilament or biothesiometry assessment in vault
- Given 3+ years elapsed and ongoing suboptimal glucose control (fructosamine 310 µmol/L, Apr 2026), neuropathy progression is likely
