Degenerative Cervical Myelopathy body chart — Illustrative, not diagnostic. Canva body chart for Degenerative Cervical Myelopathy.

This entire page is free, permanently.

Who: Middle-aged and older adults. It looks like ageing, and that is exactly the trap.
What: Hands that have stopped being reliable. A gait that has changed. Neck pain that came with them.
How it behaves: Slowly. Nothing about the onset says "refer".

The one thing to take from this page:

It is missed for years, and the mechanism of the miss is a physiotherapy-shaped problem.

Figure	Population
Mean time from symptom onset to diagnosis	2.2 ± 2.3 years — 42 surgical cases, retrospective, single centre
Modal delay	1–2 years — 778 self-reported patients
Delay predicted greater disability on patient-derived mJOA	p = 0.001, same cohort
Greater delay in Black or African American patients	p = 0.010, same cohort
Diagnosis was made by a family physician in	4.8% of cases — neurosurgeons 38.1%, neurologists 28.6%, orthopaedic surgeons 19%
First presented to a family practitioner or an orthopaedic surgeon	90.4%

[1][2]

And in a UK musculoskeletal triage service staffed by specialist physiotherapists, 27 cases spent an average of three months inside the service. It was suspected faster when patients had both upper-limb symptoms AND gait disturbance or pathological reflexes. It was slower when there was no gait disturbance, or a normal or incomplete neurological assessment — and slowest of all when electrophysiology was ordered to chase a peripheral neuropathy [3].

⚠️ No Australian guideline exists for this presentation. Anchored to the AO Spine clinical practice guideline [4], verified as still current. An Australian — John W. Middleton, University of Sydney — is a named author on it.

Pattern > Label. And this one barely has a label yet: diagnostic criteria and screening criteria are both still in development.

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

Five stages, in your course's order. Insidious, so BEHAVIOUR before HISTORY.

MAIN PROBLEM

"I keep dropping things." "My handwriting's gone." "I'm not steady."

And often, first: "my neck hurts."

BODY CHART

Neck and shoulder pain, hands, and — critically — legs. Ask about the legs.
Bilateral hand symptoms in a pattern that fits no single nerve.

BEHAVIOUR

Progressive, over months. Not mechanical, not clearly load-related.
Balance in the dark, on uneven ground, in the shower. Romberg's sign is only 42% sensitive as a test — but the question is free.
Ask specifically: buttons, coins, keys, handwriting. (These are descriptive. No diagnostic data attaches to them — say so if asked.)

HISTORY

How long, and is it getting worse? Progression is the diagnosis.
Falls, near-falls, changes to how they walk.
Previous neck surgery, rheumatoid arthritis, Down syndrome.

SPECIAL / SCREENING QUESTIONS

Bladder and bowel change, sexual function, and any leg symptoms. See below — bladder is a late sign, not a screening question.

Which symptoms have data, and which do not

This distinction is the quality of your reasoning.

Frequency across 58 DCM cohorts — how often it appears in people who HAVE the disease [5]:

Symptom	Frequency
Unspecified paraesthesia	86%
Hand numbness	82%
Hand paraesthesia	79%
Gait impairment	72%
Neck and/or shoulder pain	51%
Bladder	38%
Bowel	23%
Sexual	4%

Frequency in a diagnosed cohort is NOT diagnostic accuracy. Only 3 of those studies had a control group.

Discrimination — 139 DCM patients versus 108 age-matched healthy controls, prospective [6], reported as Youden index:

Symptom	Youden index
Neck pain	63% — the best single symptom
Upper-limb numbness	57%
Hand clumsiness	50%
Walking imbalance	50%
Upper-limb weakness	46%

Neck pain is the best single discriminating symptom, and it is usually taught as an afterthought. That is counter-intuitive and it is worth printing.

And bladder change is a LATE sign. 38% frequency, and the least prevalent symptom in one cohort. Its absence rules out nothing.

3 · HYPOTHESIS RANKING

Competing pattern	The one discriminating feature
Ageing	The default assumption, and the reason it is missed. Progression is what separates them
Bilateral carpal tunnel syndrome	No gait change, no hyperreflexia, no leg symptoms. This is the mimic that matters most
Cervical radiculopathy	A dermatomal and myotomal pattern, usually unilateral, no upper motor neurone signs
Peripheral neuropathy	Distal, symmetrical, glove-and-stocking — and the electrophysiology ordered to chase it caused the longest delays
Cervical arterial dysfunction	Acute, painful, and vascular — see that page
Other cord pathology — MS, tumour, syrinx	Younger, different progression, other neurological features

The trap, named

Early DCM looks like ageing, or like bilateral carpal tunnel. That is the framing of the current musculoskeletal review, and it is the most useful sentence a student can carry [7].

The way to break it: check the legs, and check the reflexes. Bilateral carpal tunnel does not change a gait and does not produce hyperreflexia.

And a scan is not a diagnosis

In 183 randomly recruited volunteers aged 40–80 (median 66), imaged on 1.5T MRI [8]:


MRI cord compression	108/183 = 59.0%
Rising to, in the eighth decade	66.8%
Clinical myelopathy	2/183 = 1.1%

Compression and disease are not the same thing. Fifty-nine per cent of ordinary over-40s have the finding. One per cent have the condition.

Jones' hypothesis categories that change your plan: pathophysiology — this is a cord problem, not a joint problem — and precautions, which govern everything you do next.

Hand clumsiness plus an unsteady gait means think cord. That pearl is taught already, and the data support it.

4 · RED FLAGS — DON'T MISS THIS

The whole page is the red flag. This section is how you personally will miss it — and what to do instead.

How the diagnosis gets lost

From a UK musculoskeletal triage service run by specialist physiotherapists, 27 cases over 2.5 years [3]:


Faster when	Upper-limb symptoms AND gait disturbance or pathological reflexes were present together
Slower when	No gait disturbance was noted
Slower when	The neurological assessment was normal or incomplete
SLOWEST when	Electrophysiology was ordered to chase a peripheral neuropathy

And the mechanism has been measured. Across primary care, secondary care and surgical assessment of 43 DCM patients, reporting of limb pain, objective weakness, hyperreflexia, Hoffmann's, extensor plantar response and lower-limb spasticity all differed significantly between assessors — and "pathological reflexes were least frequently assessed by primary care doctors" [9].

You will not miss this because it is subtle. You will miss it because you did not test the thing that finds it.

What must be in the examination

Do this	Why
Walk them. Observe gait, then tandem gait	Gait impairment is 72% frequent, and its absence in the notes predicted delay
Test reflexes — upper AND lower limb	Hyperreflexia pooled sensitivity 0.79; lower limb 0.85 (0.81–0.88)
Test the upper motor neurone signs — Hoffmann's, Babinski, clonus, inverted supinator	§5 for what each is worth
Full neurological exam — power, reflexes AND sensation, bilaterally	Your course requires all three recorded
Score the mJOA	It is how the referral gets triaged. §5

Escalation

Finding	Action
Rapid neurological decline, inability to walk, or new sphincter dysfunction with cord symptoms	Emergency assessment
Progressive hand or gait change without rapid decline	Urgent neurosurgical referral
Established bladder or bowel involvement	Urgent — this is late disease
mJOA 0–11 (severe) or 12–14 (moderate)	Surgery is recommended. Urgent referral
mJOA 15–17 (mild)	Definite referral, not necessarily urgent — the guideline offers surgery OR structured rehabilitation
Suspected DCM at all	A surgical opinion. Every symptomatic patient

And the natural history is why "definite" matters even for mild disease. Pooled neurological stability without surgery ([10], Bayesian 95% credible intervals):

	Mild	Moderate/severe
1 year	91% (83–97)	83% (76–89)
5 years	75% (54–90)	55% (41–68)
20 years	65% (39–86)	43% (25–58)

A quarter of mild DCM deteriorates by five years — with an interval running from one in ten to nearly half. And separately, 20% to 60% deteriorate over time without surgery on moderate-strength evidence [11].

The manual therapy precaution

Assess for myelopathy BEFORE you manipulate. Four patients in one tertiary unit over ten years deteriorated acutely after manipulation — three after chiropractic adjustment, one after tuina; three required surgery [12].

Keep the precaution. Drop the rate. Four cases, no denominator — a risk cannot be computed, and the authors themselves state manipulation "remains an important and generally safe treatment modality".

Urgent is for moderate and severe. Mild is a definite referral that the guideline itself says may be managed with structured rehabilitation.
You will miss this because you didn't walk them and didn't test their reflexes.
Assess for myelopathy before you manipulate a neck. The precaution is right; the risk has never been measured.
