Vascular vs Neurogenic Claudication body chart — Illustrative, not diagnostic. Canva body chart for Vascular vs Neurogenic Claudication.

This entire page is free, permanently — all seven sections. Red flag content is never gated in CliniStudy.

Who: Older adults with exertional leg symptoms. Smoking, diabetes, hypertension, kidney disease and known vascular disease raise the vascular stakes.
What: Peripheral artery disease (vascular claudication) · lumbar spinal stenosis (neurogenic claudication) · or both.
How it behaves: Leg pain, heaviness, cramping, numbness, fatigue or weakness that limits walking and settles with rest.

The one thing to take from this page:

The question is not which one it is. The question is whether you have checked the vessels at all.

You'll often be taught a clean fork. Here's what the evidence adds.

The taught rule	What the evidence says
Relief on sitting or bending forward = neurogenic	A good first move. Individual symptom attributes are weak discriminators on their own [1]
Relief on standing still = vascular	Same caveat. Constellations discriminate; single symptoms don't
Work out which one, then treat it	Some have both: PAD turned up in 6.7 % of a stenosis cohort, about half of it undetected [2]
An experienced clinician can tell	Masked surgeons mostly agreed — but still disagreed on individual cases, and the physical exam items reproduced poorly. The history carries it [3]

Keep the pearl. It is the right first move. Then stop treating it as the answer.

⚠️ No Australian guideline governs this. Anchored to the ACC/AHA peripheral artery disease guideline [4] and the non-surgical lumbar spinal stenosis guideline [5]. Both non-Australian, and neither written for the appointment where you don't yet know which it is.

2 · SE — THE SUBJECTIVE PATTERN (the 70%)

Five stages, in your course's order. Behaviour carries this pattern — it is one of the few presentations where the aggravating and easing detail genuinely discriminates, provided you take the whole constellation rather than one line of it.

MAIN PROBLEM

"I can only get about a hundred metres and then my legs give out."
"My calves cramp up and I have to stop."
"I'm fine on the shopping trolley. It's walking upright that kills me."

BODY CHART

Where in the leg? Calf-dominant cramping leans vascular. Symptoms above the knees, or variable and changing between episodes, lean neurogenic.
Mark both legs and note whether the distribution is the same each time. Neurogenic symptoms often wander; vascular symptoms usually don't.
Mark skin changes, colour change, ulcers or trophic changes if present.

BEHAVIOUR

This is the section, and take all of it, not one line.

	Leans vascular	Leans neurogenic
What relieves it	Standing still	Sitting, or bending forward
Posture on walking	No preference	Shopping-cart sign — better leaning on a trolley
Downhill walking	Usually easier (less work)	Often worse — more extension
Cycling	Symptoms come on with effort	Usually well tolerated — flexed and unloaded
Distance to onset	Often fairly consistent	More variable
Symptom quality	Cramping, tightness	Heaviness, numbness, weakness

And write down the walking distance. It is your outcome measure, it is repeatable, and walking capacity is not captured by a static examination (Rainville et al. 2012).

HISTORY

Smoking, diabetes, hypertension, kidney disease, hyperlipidaemia, known cardiovascular or cerebrovascular disease. The vascular risk set.
Known lumbar stenosis, previous spinal imaging, previous spinal surgery.
Is it progressing? Reducing walking distance over months matters on either branch.

SPECIAL / SCREENING QUESTIONS

Rest pain, night pain in the foot relieved by hanging the leg out of bed — critical limb ischaemia. This is not a claudication question any more.
Non-healing wounds, ulcers, tissue loss.
Bladder, bowel or saddle change; progressive leg weakness. The cauda equina screen runs alongside the neurogenic branch, every time.

3 · HYPOTHESIS RANKING

Competing pattern	The one discriminating feature
Neurogenic claudication (lumbar spinal stenosis)	Relief on sitting or bending forward, shopping-cart posture, normal pulses, possible weakness or reflex loss.
Vascular claudication (peripheral artery disease)	Relief on standing still, calf-dominant cramping, diminished pulses, cool skin, delayed capillary refill.
Lumbar radicular pain	Dermatomal leg pain at rest as well as on walking, with a positive SLR or slump. It doesn't wait for you to walk.

The fourth option the table can't show

Both. Peripheral artery disease sits alongside lumbar spinal stenosis in a real minority of older adults, and those patients improve less (Uesugi et al. 2012), and atypical presentations are common. Which is why:

A confident spinal diagnosis does not exclude peripheral artery disease — and an incomplete response to spine-focused treatment is a vascular screening prompt, not a loading problem.

And remember what stenosis actually is. Lumbar spinal stenosis is a clinical syndrome, not an MRI finding (Lurie & Tomkins-Lane 2016). A scan showing canal narrowing in someone whose symptoms are vascular explains nothing.

4 · RED FLAGS — DON'T MISS THIS

This section is free, on every pattern, forever. Safety is never gated.

The escalation set

Finding	What it means	What you do
Rest pain or night foot pain relieved by dependency	Critical limb ischaemia	🚑 Urgent vascular referral
Tissue loss, ulceration, gangrene, non-healing wound	Limb-threatening	🚑 Urgent vascular referral
Sudden painful, pale, pulseless, cold, paraesthetic leg	Acute limb ischaemia — amputation runs up to 25%, and the longest delay is before the patient sees any doctor (Londero et al. 2014) [20]	🚑 Emergency department, now — and tell anyone with known PAD not to wait for their next appointment if it happens
Diminished or absent pulses, cool skin, delayed capillary refill	Suspected PAD	ABI and vascular assessment
Progressive neurological deficit	Neurogenic branch, escalating	Urgent medical / surgical review
Bladder, bowel or saddle change	Cauda equina	🚑 Emergency department, now

The two rules that survive everything else

1. Always palpate pulses in an older adult with exertional leg pain. This is the single action that prevents vascular disease being treated as a spine problem. It costs thirty seconds.

2. Don't let a plausible spinal story stop the vascular screen. The two coexist. An incomplete response to spine-focused care is a prompt to check the vessels.

Guideline anchor

No Australian guideline covers this differentiation for physiotherapists.

Two non-Australian anchors, one per limb: the ACC/AHA peripheral artery disease guideline (Gornik et al. 2024, PMID 38743805) for the vascular side, and the clinical practice guideline for non-surgical management of lumbar spinal stenosis with neurogenic claudication (Bussières et al. 2021, PMID 33857615) for the neurogenic side. Exercise management on both sides is anchored to Cochrane reviews (Lane et al. 2017, PMID 29278423; Hageman et al. 2018, PMID 29627967; Ammendolia et al. 2013, PMID 23996271).

PubMed Source

Neither anchor is Australian, and neither is written for the moment this page is about — the appointment where you do not yet know which of the two it is. The differentiation content is anchored to primary evidence, and the page is explicit that the two conditions frequently coexist, which is the part guidelines on either side tend not to emphasise.
