A Novel Method for Recording Tremor

Effect of propranolol on acute withdrawal tremor in alcoholic patients.

“…The principle of using a light source in the beam of which the patient's hand should be kept (Cooper et al, 1957;Fish, 1964) and those based on electromagnetic detectors (Jasper and Andrews, 1938;Friedlander, 1956), as well as those where piezoelectric change of titanate ceramic transducers are used (Rushworth and Willison, 1960), have the disadvantage that the patient must hold his hand during the recording in a previously specified area-for example, within a beam of light or on a disc. Similar limitation is involved if the strain gauge itself (Tuttle et al, 1951) upon which the patient's hand has to rest is supported or if the patient has to hold a stylus in a hole (Karkalas et al, 1972).…”

Quantitative Assessment of Thalamotomy for Parkinsonism

“…The literature on quantitation of Parkinsonism is scant [3,8,9,10]. Bard [1] and Canter [5] scored simple physical activities of everyday life in an attempt to arrive at a quantitative assessment of Parkinsonian disa bility.…”
