LANSS Pain Scale

LANSS pain scale (Bennett 2001): weighted symptom and exam items totaling 0-24; a score >= 12 suggests pain of predominantly neuropathic origin.

Example

Dysesthesia — pricking/tingling/pins-and-needles
Yes
Skin looks different — mottled/red
Yes
Exam: brush allodynia
Yes

Result: LANSS 15 of 24 — neuropathic mechanisms likely (>= 12).

The tool opens with these values already filled in. Replace them with your own.

What the result means

< 12
Neuropathic mechanisms unlikely.
>= 12
Pain of predominantly neuropathic origin likely (weighted symptom + exam items, 0-24). A screening tool, not a diagnosis.
