title: Akinetic freezing and trick movements in Parkinson's disease.
abstract: The clinical features of akinetic freezing occurring in a group of 85 patients with idiopathic Parkinsonism and the individual methods used to overcome immobility are described. Frequency and severity of attacks are related to duration of disease and are not amenable to currently available medications. The pathogenesis and therapeutic implications are briefly discussed.
