Cervical Myelopathy

Spine

Overview

Cervical myelopathy is a progressive neurological condition resulting from compression of the spinal cord in the cervical spine, causing motor weakness, sensory disturbance, and gait abnormalities. It represents a serious pathology requiring careful differential diagnosis and often specialist imaging and intervention. Early recognition is critical to prevent irreversible neurological damage.

Pathophysiology

Cervical myelopathy develops when structural narrowing of the cervical spinal canal compromises spinal cord function. Common causes include cervical spondylosis (degenerative disc disease and osteophytes), disc herniation, ligamentum flavum hypertrophy, and less commonly ossification of the posterior longitudinal ligament or spinal cord trauma. The compression causes direct mechanical injury, impairs microvascular circulation, and triggers inflammatory cascades leading to demyelination and axonal loss. Chronic compression results in progressive neuronal dysfunction and irreversible damage if untreated.

Patient Education

Early recognition and appropriate medical referral are essential—cervical myelopathy can cause permanent neurological damage, so patients must understand the importance of imaging and specialist evaluation to prevent progression.

Typical Presentation

Site

Cervical spine with radiating symptoms into upper extremities, trunk, and lower extremities; symptoms often bilateral and asymmetrical

Quality

Numbness, tingling, weakness, clumsiness of hands; may report heaviness in limbs, electric shock sensations; gait disturbance described as stiffness or loss of coordination

Intensity

Highly variable; ranges from mild subtle symptoms to severe progressive functional loss; often insidious onset with gradual deterioration

Aggravating

Neck extension, overhead activities, prolonged neck positioning, sometimes neck flexion-extension movements; symptoms may progress gradually over weeks to months

Relieving

Neck flexion may temporarily ease symptoms in some cases; symptoms often present at rest and worsen with activity or positional stress

Associated

Hand clumsiness, difficulty with fine motor tasks, gait imbalance, lower extremity weakness, bowel/bladder dysfunction (severe cases), hyperreflexia, positive Hoffmann's sign, positive Lhermitte's sign, spasticity, loss of proprioception

Orthopaedic Tests

Test descriptions are written with AI assistance from standard clinical texts. Where a test lists Sources, its description has been checked against them; those sources are independent and do not endorse OsteoKit. Accuracy figures and grades (A–D) appear only when checked against the published study; tests without one are marked “No accuracy study”.

Further reading: full test procedures are described in standard clinical examination texts, e.g. Magee & Manske, Orthopedic Physical Assessment (7th ed.), and Cook & Hegedus, Orthopedic Physical Examination Tests: An Evidence-Based Approach (2nd ed.).

Grade A
A+ABCDStrong clinical value: substantially changes the diagnosis (LR ≥10 or ≤0.1)
best for ruling IN (confirmation).

Finger Escape Sign

Procedure

Patient holds both hands in front of chest with fingers extended and adducted for 20–30 seconds while the examiner observes for involuntary finger dropping or loss of position.

Positive Finding

Unilateral or bilateral involuntary finger dropping or inability to maintain finger position and adduction

Sensitivity / Specificity

22%/98%

Reference: Kato Y et al., Spine Surg Relat Res 2025; PMID 40223840

Interpretation

Suggests intrinsic hand muscle weakness due to cervical myelopathy (typically C8–T1 involvement). Because this sign is specific but INSENSITIVE, a positive finding supports ruling IN myelopathy, whereas its absence does NOT exclude cervical myelopathy. It must therefore not be used as a screening test — screening requires a sensitive test, not a specific one. Diagnosis rests on the overall clinical picture (gait disturbance, hyperreflexia, Hoffmann's/Tromner, inverted supinator, Babinski, clonus) confirmed by MRI

Sources

Grade B
A+ABCDGood clinical value: meaningfully changes the diagnosis in one direction (LR 5–10 or 0.1–0.2)
best for ruling OUT (screening).

Upper Limb Tension Test (ULTT)

Procedure

Patient supine. With the shoulder girdle held down, abduct and externally rotate the shoulder, supinate the forearm, extend the wrist and fingers and then the elbow. Add neck side-flexion away from and towards the test side.

Positive Finding

Reproduction of the familiar arm symptoms that changes with neck side-flexion.

Sensitivity / Specificity

97%/22%

Reference: Wainner RS et al., Spine 2003; PMID 12544957

Interpretation

A test for nerve-root or peripheral nerve irritability, not for myelopathy. It helps identify a nerve-root component, which can coexist with cord compression (myeloradiculopathy). Note: these figures derive from cervical radiculopathy populations (Wainner 2003); not validated specifically for myelopathy.

Sources

Grade D
A+ABCDLimited value: little effect on the diagnosis on its own
limited standalone value (graded conservatively from a reported range).

Hoffmann's Sign (Hyperreflexia of Finger Flexors)

Procedure

Hold the patient's relaxed middle finger and flick the nail downwards. Test both hands.

Positive Finding

Reflex flexion of the thumb and index finger, especially if on one side only.

Sensitivity / Specificity

58–62%/50–86%

Reference: Jiang Z et al., Global Spine J 2024; PMID 37903098

Interpretation

An upper motor neuron sign in the arm that supports cervical cord compression. Some healthy people have a mild, symmetrical response, and many people with myelopathy do not have it, so interpret it with the other signs (brisk reflexes, clonus, Babinski sign, gait and hand clumsiness).

Sources

Contested
Reported accuracy varies widely across studies — may be strong or weak depending on population and technique
Evidence is highly heterogeneous: reported figures span from a weak (D) to a strong (APlus) test across studies/populations. Interpret with caution and in context.

Inverted Supinator Sign

Procedure

Patient seated, forearm resting in mid-position on the thigh. Tap the brachioradialis tendon just above the wrist with a reflex hammer.

Positive Finding

Little or no elbow flexion (reduced brachioradialis reflex) with a brisk reflex flexion of the fingers.

Sensitivity / Specificity

18–75%/78–99%

Reference: Jiang Z et al., Global Spine J 2024; PMID 37903098

Interpretation

Suggests a lesion at C5–C6: the root at that level is affected (reduced reflex) while the cord below is irritated (brisk finger response). A positive sign adds weight to a diagnosis of cervical myelopathy, but its absence does not exclude it.

Sources

No accuracy study

Lhermitte's Sign

Procedure

Patient seated. Ask the patient to bend the head forward, or flex the neck gently, and report any unusual sensations.

Positive Finding

A brief electric-shock sensation running down the spine or into the limbs on neck flexion.

Interpretation

Points to irritation of the spinal cord, from compression (cervical myelopathy) or other causes such as multiple sclerosis. It is often absent in myelopathy, so its absence does not exclude cord compression. A positive sign needs medical referral.

No accuracy study

Romberg Test (Standing Balance)

Procedure

Ask the patient to stand with feet together, first with eyes open and then eyes closed, for 30 seconds. Stand close by to prevent a fall.

Positive Finding

Balance is maintained with eyes open but lost with eyes closed.

Interpretation

Shows loss of position sense, which can come from the dorsal columns of the cord (as in myelopathy) or from peripheral neuropathy. With other myelopathy signs, such as clumsy hands or an unsteady gait, it supports referral for MRI.

⚠ Red Flags

  • •Progressive myelopathic symptoms with objective neurological deficit including weakness, hyperreflexia, or pathological reflexes
  • •Lhermitte's sign: electric shock sensation with neck flexion suggesting spinal cord involvement
  • •Gait disturbance, ataxia, or loss of coordination affecting safety and function
  • •Bowel or bladder dysfunction suggesting spinal cord involvement
  • •Severe progressive neurological decline over days to weeks
  • •Fever, night sweats, or unexplained weight loss suggesting infection or malignancy

⚡ Yellow Flags

  • •High health anxiety or catastrophizing regarding neurological symptoms
  • •Severe functional limitation affecting employment or activities of daily living
  • •Poor social support or isolation potentially delaying medical intervention
  • •Delay in seeking medical review despite worsening neurological symptoms due to health system avoidance
  • •Depression or anxiety comorbidity affecting rehabilitation adherence
  • •Litigation or compensation claims influencing symptom reporting

Osteopathic Techniques

Refer first

This condition needs medical assessment and management first. Do not use neck-directed manual techniques. Any osteopathic care is supportive, away from the injured area, and only once the treating team has cleared it. Moderate or severe myelopathy is treated with surgery, and even mild cases can deteriorate without it.

Referral Criteria

  • •Any suspicion of cervical myelopathy based on clinical presentation or examination findings (positive Hoffmann's sign, Lhermitte's sign, hyperreflexia, bilateral symptoms, gait disturbance)
  • •Progressive neurological symptoms at ANY point - refer urgently rather than continuing conservative care to a 2-4 week review. Degenerative cervical myelopathy is a progressive disease and surgical outcome correlates with the duration and severity of deficit before decompression. Progression is an indication to escalate immediately, not to complete a trial period.
  • •Objective weakness in upper or lower extremities with evidence of upper motor neuron signs
  • •Bowel or bladder dysfunction suggesting spinal cord involvement
  • •Gait disturbance or ataxia affecting safety and activities of daily living
  • •Severe pain unresponsive to conservative management
  • •Any red flag symptoms including fever, unexplained weight loss, night sweats, or trauma history
  • •Requirement for imaging (MRI cervical spine) to confirm diagnosis and assess degree of cord compression
  • •Consideration for specialist neurosurgical or orthopedic spine consultation if imaging confirms myelopathy
  • •Failure to improve with conservative osteopathic and physiotherapy management by 4-6 weeks. IMPORTANT: this criterion applies only to the stable patient who is simply not improving. DETERIORATION at any stage warrants immediate referral and must never wait for a scheduled review point.
  • •Patient with significant functional limitation or neurological compromise warranting urgent specialist input
  • •Consideration of surgical intervention if imaging shows severe cord compression with progressive neurological deficit
