title: Sudden onset of cervical spondylotic myelopathy during sleep: a case report.
abstract: Cervical spondylotic myelopathy is a common cause of compressive spinal cord dysfunction. The typical course involves either a gradual or an episodic increase in symptoms and neurologic deficits, with impairment evolving over a period of months to years. Acute neurologic deterioration in conjunction with cervical spondylosis has been described almost exclusively in traumatic situations such as disk herniation. We report a case of an acute, nontraumatic onset of tetraplegia in association with cervical spondylosis. A 56-year-old man developed tetraplegia during a 1-hour nap, with loss of volitional control of his extremities, impaired sensation below the C3 dermatome, and increased muscle tone. Magnetic resonance imaging of the cervical spine revealed canal stenosis and increased T2 signal within the cord. This case report describes the rehabilitation course for this patient and reviews the clinical spectrum of onset and progression of cervical spondylotic myelopathy.
