Radiculopathy and myelopathy in patients with primary cervical dystonia.
In a prospective series of 34 incident patients with primary cervical dystonia (CD), 6 showed clinical or radiological signs of cervical radiculopathy (RP) or myelopathy (MP) during the course of their movement disorder. Age at onset in these patients was in the range reported for pure spondylotic cervical RP without an accompanying movement disorder. Radiologically, spondylosis was mild in 1 case and absent in 2 cases. The intervals between onset of CD and RP were shorter than in literature reports of RP/MP in dystonic-athetotic patients of cerebral paresis. Clinically, RP/MP in patients with CD mostly appears at mid-cervical levels, whereas cases with cerebral paresis are more frequently affected at higher cervical segments. We propose that RP/MP does not occur more frequently in CD than in pure spondylotic cervical RP.
