Abstract
A single blind placebo-controlled study has been performed in order to investigate objectively the acute tremorolytic effect of oral L-Dopa in ten parkinsonians chronically treated with L-Dopa. Finger tremor was assessed by means of a computerized accelerometer method, at rest and during maintenance of a fixed posture. Both resting and postural tremor were significantly influenced by L-Dopa.
An “acute test” with oral L-Dopa, especially when different tremor components are investigated, may be useful for identifying objectively parkinsonians whose tremor does not respond to drug therapy or shows a deterioration of drug-responsiveness.
Sommario
Uno studio controllato con placebo è stato condotto su 10 pazienti affetti da morbo di Parkinson idiopatico, in trattamento cronico con L-Dopa, allo scopo di valutare in modo obiettivo l'effetto tremorolitico della L-Dopa.
Il tremore è stato valutato alle mani mediante una metodica di accelerometria computerizzata, sia in condizioni di riposo che di postura. In entrambe le condizioni l'effetto tremorolitico della L-Dopa si è rivelato significativo.
Un “test acuto” con L-Dopa orale, in particolare con l'esplorazione di componenti diverse del tremore, può risultare utile per una valutazione obiettiva di casi di Parkinson che non rispondano alla terapia farmacologica o che manifestino un deterioramento della risposta alla L-Dopa.
