    Objective: The CATSYS Tremor Pen has been used in several studies for measurement of tremor among workers with occupational exposure to neurotoxins like mercury and manganese. The main purpose of this study was to investigate whether recording time has an impact on the measured tremor characteristics. Other aims were to investigate whether there are interactions between recording time and age, and between recording time and (selfreported) nicotine use, respectively; to assess the test-retest repeatability of the instrument; to investigate a possible practice effect when performing the test repeatedly; and to evaluate agreement with another tremor test. Methods: The participants (n=44) consisted of former shipyard workers (mean age 67 years, range 59–76 years). Postural hand tremor was evaluated using the CATSYS Tremor Pen. Five tremor rec..
