Cervical hyperflexion elongates the dural sac, meninges, spinal cord, and nerve roots under resistance, leading to stretching or tearing. Conditions such as spinal cord compression or demyelination cause an activation of ascending spinothalamic tracts at the cervical level during neck flexion.
Sharp, shooting nerve pain that radiates down the spine or the extremities
Suggestive of sclerotic cord lesions or other scarring in the cord or dura
Causes may include but are not limited to demyelination in multiple sclerosis (MS), B12 deficiency, cord tumors, posterior column trauma or disease, meningeal adhesions or irritation, stenosis, or disc herniation
Clinically suspected cervical myelopathy is confirmed by MRI
