After signing a consent form, a 70-year old semi-retired male engineer in good general health reported that he had had tremor in his hands, but nowhere else, for 25 years. He recalled his father having had the same tremor. A general practitioner had diagnosed this engineer’s case as familial tremor. He had also heard it termed “anticipatory tremor”—it occurred mainly when he moved his hands to undertake some action.
Over time the tremor had gained in amplitude. When he held a piece of paper, he had a hard time reading because his hands would shake. When he lifted up a briefcase, his hand would “go wild”, with jerks of a full inch back and forth. However, the tremor was not so bad as significantly to disrupt his manual activities at work. He is right-handed. The tremor was worse in his left hand than in his right at a ratio that he estimated as 3:2.
