Lumbar Postural Pain (Sustained-Posture Low Back Pain) body chart — Illustrative, not diagnostic. Canva body chart for Lumbar Postural Pain (Sustained-Posture Low Back Pain).

High volume, low complexity, and the one where students most often teach the wrong model.

Illness script in one line: dull aching low back discomfort with no injury, building through a day of sustained sitting or standing, worst at the end of the day, relieved within minutes by getting up and moving.

Caseload frequency: constant. On an outpatient MSK placement this is one of the most common stories you'll take, and it is very often bundled in with neck and shoulder complaints from the same desk.

Why a low-risk pattern still gets a page

Because the standard explanation for it is weaker than students think. Read further: low back pain and lumbar lordosis [1], sitting time, posture and behaviour in office workers [2], sitting posture and the lumbar discs [3].

Associations exist. A causal "bad posture causes back pain" story does not survive the reviews.

Clinical pearl: "active movement is the antidote, avoid over-cueing posture." This page makes sure you can defend it.

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

MAIN PROBLEM

"My back aches by the end of the day." No injury. No moment. If they can name the moment, you're on a different page.

BODY CHART

Central or bilateral low lumbar ache. Diffuse. They wave a hand over it rather than pointing.
± thoracolumbar or gluteal spread. Non-dermatomal.
Often a neck and shoulder component from the same desk. Ask.
No leg pain. No pins and needles. No numbness.

BEHAVIOUR — this section IS the diagnosis

Aggs: sustained sitting, sustained standing, long drives, the back half of the working day. Cumulative, not incident-based.
Eases: standing up, walking, stretching, changing position, the weekend. Within minutes, not hours.
Night: night pain, or pain unrelieved by any position, is a §4 flag — this pattern is gone by the time they've walked to the car.
Severity: VAS 0–10 at best / at worst / right now.
The signature: a clean time-of-day curve. Fine in the morning, building by mid-afternoon, worst at six, gone by the time they've walked to the car.
Coding: M — morning stiffness minimal or under 30 minutes.
Irritability: LOW. Little or no resting symptom, needs a sustained provocation to bring it on, settles quickly with movement. That's a full-examination, full-treatment session.

HISTORY

Gradual onset, no mechanism. Often traceable to a change: a new job, a new desk, a return to the office, a laptop on a kitchen table.
Ask specifically about working from home. Read further: musculoskeletal pain in office workers versus teleworkers [4]. The question is still worth asking — the home setup is usually worse and nobody has assessed it.
Total sitting time and how it's broken up, not just the chair.
Physical activity outside work. This is the single most useful history question on the page.
Read further: occupational prevalence and ergonomic risk factors among office workers [5], management of occupational low back pain in Australia [6][7].

SPECIAL / SCREENING QUESTIONS — yes, even here

Bladder, bowel, saddle, bilateral leg symptoms. Night pain. Weight loss. Fever. Cancer history. Steroid use. Unexplained fatigue.

Typical descriptions list "no neurological symptoms" under this pattern's subjective. Read that as a description of the typical presentation, not as permission to skip the screen. Read further: red flags to screen for malignancy and fracture [8].

3 · HYPOTHESIS RANKING

Top three, and the one feature that separates each

Pattern	The discriminating feature
1. Lumbar postural pain	Cumulative through the day, no mechanism, relieved within minutes by movement, full pain-free range, low irritability.
2. Lumbar discogenic pain	Morning stiffness, worse with sitting AND with getting up from sitting, flexion more limited than extension. Postural pain is fine in the morning; discogenic is not.
3. Chronic non-specific LBP	Continuous, not tied to a time-of-day curve, longer history, fear-avoidance and psychosocial load already established. Postural pain is often the entry point to it.

Also on the list

Pattern	The discriminating feature
Lumbar instability	Episodic, transition-provoked, catch on the way back up from flexion.
Spondylolisthesis	Extension-provoked, worse with prolonged standing specifically, palpable step.
Hip osteoarthritis	Groin pain, restricted internal rotation. Sitting is often the aggravator here too.
Axial spondyloarthritis	Under forty, morning stiffness over 30 minutes, BETTER with exercise and WORSE with rest. The inflammatory time pattern is the mirror image of this page — learn both together.

What outranks all of it

Metastases · infection · fracture · cauda equina · AAA. A dull ache with no mechanism is exactly how some of these start.

4 · RED FLAGS — DON'T MISS THIS

Free forever. Safety is never behind a paywall.

This is the pattern where screening gets skipped, because everything about it looks benign — and usually is.

Finding	What it means
Bladder or bowel change, saddle anaesthesia, bilateral leg symptoms	Cauda equina. EMERGENCY. Same day.
Night pain, or pain unrelieved by any position	This pattern is relieved by movement within minutes. If it isn't, it isn't this.
Weight loss, fever, cancer history, unexplained fatigue	Urgent review.
Any leg pain, numbness, weakness or paraesthesia	Wrong page. Screen and re-rank.
Under forty with morning stiffness over 30 minutes, better with exercise	Inflammatory. Not postural. Refer for review.
Minor trauma in an osteoporosis-risk patient, or long-term steroid or immunosuppressant use (Verhagen et al. 2016) [21]	Vertebral fracture. Image.

The trap that belongs to this page specifically

"No neurological symptoms" is often taught as a feature of this pattern. It describes the typical case. It is not a rule-out and it is not permission to skip the neurological screen.

Relieved by movement within minutes is the finding. Not relieved by anything is a different conversation.

Any red flag: stop, escalate, and check it with your educator.

Guideline anchor

The Australian anchor is the ACSQHC Low Back Pain Clinical Care Standard (2022) for a new episode or flare-up (screening, no routine imaging, education, early management), though postural low back pain itself is not a guideline-level diagnosis anywhere and the standard says nothing about posture.

The other Australian material is occupational: regional variation in management strategies for occupational low back pain in Australia (Xia et al. 2026, PMID 42084752) and clinical management of occupational low back pain in Australia (Hush et al. 2008, PMID 18780162). The evidence anchor is a meta-analysis of the relationship between low back pain and lumbar lordosis (Chun et al. 2017, PMID 28476690), a scoping review of low back pain and sitting time, posture and behaviour in office workers (Alaca et al. 2025, PMID 40111906), and a meta-analysis of exercise for office workers with low back pain (Jones et al. 2024, PMID 38219373). Management otherwise anchors to the chronic low back pain guideline set via the non-specific LBP page..

PubMed Source

There is no clinical practice guideline for postural low back pain; the ACSQHC standard covers it only as low back pain. The Australian papers cited are about occupational management and service variation, not about how to treat this presentation.
