Cervical myelopathy is spinal cord dysfunction caused by compression of the cervical spinal cord, most commonly from degenerative cervical spondylosis (disc osteophyte complex, facet hypertrophy, ligamentum flavum hypertrophy). It is the most common cause of spinal cord dysfunction in adults over 55. The classic clinical picture includes gait ataxia, hand clumsiness (difficulty with fine motor tasks), bladder urgency, and Lhermitte sign (electric shock sensation down the spine with neck flexion). Cervical myelopathy causes a characteristic myelopathic gait that responds specifically to walking cane use.
Myelopathic Gait: Characteristics
Cervical myelopathy affects the spinal cord tracts that control gait:
- Dorsal column involvement: proprioceptive loss in the legs causes sensory ataxia; Romberg positive (worse balance with eyes closed)
- Lateral corticospinal tract involvement: upper motor neurone weakness and spasticity in the legs; scissor gait or spastic gait pattern
- Combined features: the typical myelopathic gait is wide-based, stiff-legged, with reduced arm swing and impaired balance on turns
- Hand involvement: concurrent hand weakness/clumsiness makes cane grip important to address
Walking Cane for Cervical Myelopathy
A walking cane provides multiple benefits in myelopathic gait:
- Proprioceptive supplement: additional ground contact compensates for impaired lower limb proprioception
- Reduces fall risk from sensory ataxia and Romberg-positive balance
- Provides anterior stability for the wide-based, stiff-legged gait pattern
- Falls in cervical myelopathy are particularly dangerous: the compromised cervical cord is vulnerable to further injury from a fall
Cervical Myelopathy Severity and Cane Use
| mJOA Score | Myelopathy Severity | Walking Aid |
|---|---|---|
| 15-17 (mJOA mild) | Mild; some gait instability; functional | Cane on challenging terrain; single-point cane |
| 12-14 (mJOA moderate) | Significant gait ataxia; falls risk | Cane for all walking; essential for safety |
| Less than 12 (mJOA severe) | Severe spastic myelopathic gait; assistance needed | Rollator or walking frame; may need assistance |
Hand Weakness and Cane Grip in Cervical Myelopathy
Cervical myelopathy frequently affects hand function (intrinsic hand muscle weakness, loss of fine motor coordination). This is directly relevant to cane grip: a patient whose hands are affected by myelopathy may not be able to grip a standard cane handle safely. Ergonomic handles (DaiWalk Anatomic Grip) that allow the palm to take load rather than requiring strong finger grip are preferable. The anatomic shape also helps patients with hand clumsiness to orient the grip correctly by feel.
Post-Surgical Cervical Decompression and Cane
Cervical myelopathy is treated surgically (anterior cervical discectomy and fusion, or posterior laminectomy/laminoplasty). Neurological recovery is variable -- early mild myelopathy recovers better than advanced severe myelopathy. Post-surgery, myelopathic gait may improve gradually over 6-18 months. A cane remains appropriate until significant gait improvement is documented.
