Cervical spine conditions are commonly associated with neck pain and arm symptoms -- but their impact on walking is less widely discussed. Cervical myelopathy and cervical radiculopathy have distinct mechanisms and distinct walking implications, and distinguishing between them is important for appropriate walking aid use.
Cervical Myelopathy vs. Cervical Radiculopathy
- Cervical radiculopathy: Compression of a nerve root exiting the cervical spine, typically from a disc herniation or osteophyte. Symptoms are in the distribution of that nerve root -- arm pain, numbness, and weakness. Walking impairment in pure radiculopathy is uncommon because the nerve roots at the cervical level supply the arms, not the legs. However, if radiculopathy affects arm function, it may impair the ability to hold and use a cane effectively
- Cervical myelopathy: Compression of the spinal cord itself at the cervical level. Because the cervical spinal cord carries all the descending motor and ascending sensory pathways for both arms and legs, cervical cord compression causes a syndrome affecting all four limbs. Walking impairment is a core feature -- the article on cervical myelopathy covers this in detail
Cervical Myelopathy Gait Features
The cervical myelopathy gait (as covered in the dedicated article) includes:
- Spastic paraparesis -- stiff, scissoring lower limb gait from upper motor neuron involvement
- Reduced walking speed and stride length
- Loss of fine foot proprioception from posterior column compression (Romberg positive in many patients)
- A characteristic unsteady, wide-based gait in moderate-severe myelopathy
- Lhermitte sign (electric shock sensation down the spine on neck flexion) -- not a gait feature but a marker of cord involvement
Impact of Cervical Conditions on Cane Use
Cervical conditions affect cane use in ways that lumbar or lower limb conditions do not:
- Arm and grip function: If cervical radiculopathy or myelopathy has caused arm weakness, grip strength for holding the cane may be reduced. The cane weight (DaiWalk: 295-340g depending on configuration) should be considered -- a lighter configuration reduces the arm effort to control the cane
- Neck posture during cane use: Looking down at the cane tip requires neck flexion, which in a patient with severe myelopathy (where neck flexion may trigger Lhermitte or worsen cord compression) should be minimised. The cane position should allow ground contact without forcing prolonged neck flexion
- Proprioceptive loss: The posterior column involvement in myelopathy reduces vibration and position sense in the feet. The cane provides a supplementary proprioceptive reference point that partially compensates for this loss
Cervical Spine Conditions and Walking: Summary Table
| Condition | Walking Impact | Cane Role |
|---|---|---|
| Cervical radiculopathy (arm only) | Minimal direct gait impact | May impair grip ability to use cane |
| Cervical myelopathy (mild) | Subtle gait change, balance impairment | Balance supplement, proprioceptive aid |
| Cervical myelopathy (moderate) | Spastic gait, wide-based, slow | Essential balance support |
| Cervical myelopathy (severe) | Significant walking disability | Single cane may be insufficient; frame or bilateral aid |
| Post-cervical surgery | Variable; myelopathy may be reversible | Cane during recovery; reassess as recovery progresses |
