title: Writing tremor myoclonus.
abstract: A patient with a 9-year history of primary writing tremor is described. Spontaneous postural tonic abduction and tremor of the right index finger was also present. Atypical features included unidirectionality of the tremor, writing-associated and independent, bilateral proximal upper limb myoclonus. No clinical response was obtained after intravenous benztropine and subtotal lidocaine infiltration of the right first dorsal interosseous muscle motor point. There was no dystonia present. This case illustrates the sporadic occurrence of writing tremor of the primary type in the absence of dystonia, otherwise a common feature of writer's cramp.
