AGUILAR, ENRIQUE et al. Orthostatic tremor causing postural instability in Parkinson disease: Report of one case. Rev. méd. Chile [online]. 2010, vol.138, n.11, pp.1410-1413. ISSN 0034-9887.

Parkinson disease (PD) is a movement disorder characterized clinically by the variable combination of rigidity, bradykinesia, rest tremor and postural instability. Usually postural instability is a late-onset manifestation and is frequently associated with axial manifestations and with a poor prognosis. We report a 67-year-old female with orthostatic tremor as the etiology of her postural instability. The patient was treated with increasing doses of clonazepam, reaching 2 mg/day, and levodopa. There was an improvement of postural instability with a good response of parkinsonian symptoms.
